Do you use SSD for DCS? Cpu and gpu is not all, you need ssd nvme for DCS.

[@KYRedleg]

I work in cybersecurity. There is definitely a risk associated with exclusion. I think all of Spuds recommendations are relatively low risk except one. You always want to be as narrow as possible when excluding a folder. I wouldn’t exclude the entire saved games folder, just the relevant sub folders. As for mods etc, I recommend downloading them to a non excluded folder before installing them so Defender can get a look before they are loaded. Thanks for info Spud!

[@chronohunter4595]

This. One of the first things I do during an assessment or after a foothold is identify excluded locations, modified environment paths, and any startup applications or services with a space in their paths. With excluded folders, I essentially have a single location on the localhost that I can do anything from without the malware protection service even batting an eye. Be careful out there.

Thank you for sharing this information. I followed the instructions in the video and have seen around a 10-15% increase in frame rates. Frame rates are much more stable and gameplay is very smooth. Thanks again for sharing.

[@hustlinmagic]

Two things I did that made a huge difference were forcing DCS to only use the performance cores. And also disabling cores that were getting stuck on 100% utilization in the main menu. In VR it was a night and day difference. DCS really doesn't seem to use 13 and 14th gen CPU's well unless you use software to manage it yourself.

[@karlhungus545]

That's only Intel. It makes no difference for Ryzen (I've tried it).

[@Hyena_91]

It made no difference for me on Win11 with a 13700KF. I think Win11 can handle the E cores better. But on Win10 it's worth a try. But disabling core parking helped me remove the stutters I got every 1-3 seconds.

[@hootman_hawk]

+1 this. I recently built a new PC with a 13900k with a Gigabyte Aorus mobo, and in the bios there is a default tweak "Disable E-Cores", and I've been setting that in Bios before running DCS. For those of you who don't have that type of pre-progammed tweek in your mobo bios, you can still find each E-core and disable it manually in the Bios.....I think it's actually 12th Gen and above that introduced E-cores.....but guys, if you have the processor and you haven't tried this, YOU MUST!. I have also had some success with some other games. Some don't like it all at, for instance Elite Dangerous throws graphical artifacts if you disable the E-cores.

[@redtailpilot]

Yep, my experience as well. Disabling E-cores on my 13700KF made a huge difference in DCS MT and VR! Using Win 10

[@p.h-bw4cj]

[@generalgrevous2458]

I use the Task Scheduler and set Winows Defender Scan to once every 2 months and seems to do the trick, and to be honest seems to be easier than your way of doing it. Of course it means nothing else will be scanned but I have a computer that is dedicated to DCS so not too worried and have been doing it for close to 3 years. But your way seems to me more practical if you're worried about other apps. 🙂👍

[@scht-sg]

While this works, the risk is very high. I wish you reconsider how you communicate this across to the mass who do not understand cyber hygiene. We just give reason for bad actors to exploit this exclusion. Even if you have other protection within your network such as EDR and network level protection, and other anti-malware capabilities to compliment your security. This is still risky. It is better to look for better security software than MS Defender as they are well known to be not well optimized. I once had a bug that the defender consumed 14GB of ram .🧐 For your reference, i am a tech consultant with 25 years experience and had skills to cyber hygiene.

[@Sunesen]

I had some major frame issues lately. What helped for me was to switch over to using the Multi-Threading option and setting the max FPS for DCS to something lower than the max FPS of my computer screen.

[@hootman_hawk]

Exactly. You can find various conversations on message boards about this. I set all my flight sims in the Nvidia Control Panel for "max frame rate" for each game to 60 fps. This is generally considered a good point as they eyeball and brain really can't see the difference above that (some have argued they CAN, maybe so. I think that is also an issue with a persons age). What I have found this does, is makes your GPU "take it easy". Running any game with FPS unrestricted is just crazy, it can cause your experience to be bad as the FPS is bouncing around all over the place. Locking at 60fps definitely also keeps it "smoother". A good way to utilize this (fine tune it), is to run MSI Afterburner utility and set it up to see your GPU and CPU settings in-game. Run the game with no FPS lock, and then 60 fps lock to see the difference with the Afterburner running in game. Basically you are giving yourself the ability to tune your "eye candy", the graphics. Then, what I do, is look at how much GPU memory is being utilized, and slowly dial up the various graphics settings both in game and in the NVCP on each game to get the GPU utilization to about 90% as seen in Afterburner. That leaves you 10% GPU overhead to handle situations where you enter graphics intense areas. So once set, I set up a situation in DCS mission editor with a lot of units, clouds, maybe at dusk, etc. to get my GPU and CPU chugging. If I haven't allowed enough overhead, I then go back and dial down some graphics settings, to get it back to where I have enough overhead (again, using MSI Afterburner in game to watch the readings.

[@tructruc4492]

i have done the same with AVAST ! It works very fine ! THX . In fact my rig is a 13600K + 64go DDR5 @6000 at cas 32 and a RTX 3070TI + TrackIr 5 . I run at 2560*1440 . I usually have a steady 120 fps ( vsynch at 120 hz and fps limited at 120 ) . Some times i had a drop of fps for no reasons and i detected that was a strange CPU usage. That's the root cause. Bingo you find the right solution ! I have tested 3 times for long sessions ! and that issue is gone ! Your are the king man ! THX again

[@Spudknocker]

Hey man make sure to report back if it helps you out!

[@damcopter]

Problem with TrackIR is that you HAVE to cap your game at 60fps or 120fps (if able to reach a steady 120....). Otherwise your game seems to stutter because TrackIR has a 120hz camera so your game need to be only at 60 or 120 to be smooth. It's a huge limitation from TrackIR. Don't know if this is your problem anyway

[@AdmiralQuality]

Hey that's pretty good! I made the changes before doing a proper "before" test but the MT version does feel a bit more playable to me now. (It hated my old i5-7500 before and I would often be forced to fly with the ST version, which is getting buggier with every update and will soon be completely abandoned.) I'll try putting it back as it was tomorrow and do some more controlled A/B tests. But this should help! Thanks Spud!

[@velvetsound]

This helped my setup (similar to yours) go from “meh” to the performance I had expected to get. As I mentioned in a comment thread I’d recommend buying better antivirus software to scan whatever you excluded from MS Defender vs having no protection at all. Defender has horrible performance for anything data intensive… but better solutions are available. At work we had to switch from Defender to a commercial solution for 9TB SQL Server data files to get the performance we expected. Better antivirus is better than no antivirus.

[@Spudknocker]

I am glad it helped you dude!

[@gofres]

Great tip, looking forward to trying this out tomorrow! I agree with the same issues of inconsistent fps and in the least logical places. I'm locked to 60fps at 4k but do get moments of it dipping to 20ish for no apparent reason.

Spud. I'm in a similar situation. I upgraded to a new computer this week. I tried what you recommended after multiplayer timed out on me consistently for the first time yesterday. I've sent a trouble ticket into Eagle Dynamics for help but wanted to see if you or any of your followers can help. I've flushed my dns, did your recommendation in this video, lowered my graphic setting, checked my internet and router, adjusted virtual memory in advance settings, system reset and reinstalled all apps and softwares. This is a major upgrade and and so confused on why this is happening since I never had this issue with my old laptop that was also on windows 11. If anyone knows anything, I'm open to any suggestion. This is 1 of 2 games I play.

[@Commoner64]

I have the same specs 14900k, 4090, 64GB ddr5 and this problem has been driving me crazy. Unfortunately this solution didn't work for me. The only thing that seems to work somewhat is disabling cores that are at 100%. Thanks for the info though.

[@EaglefireflyGaming]

Hey Spud! Nice video! One thing that made DCS butter smooth for me was putting 128gb page file on an Nvme. Even 64gb is getting low for detailed missions.

[@JPsTechReviews]

Thank you, big help for me but no trackIR but my Varjo Base and smooth sailing.

[@BenjaminJannedy]

Weird! I did exactly what was described in the video, but it didn't work for me. Sometimes it takes minutes for the missions and textures to load. Sometimes, Windows offers to kill the process, because its unresponsive for minutes. I have a very fast system as well (I7, 64G Ram, 4090), and when I fly, it's very smooth, but loading times are horrible. I have an extra NVME SSD for the game installation and windows on another SSD. Can't understand where the problem is... When everything is loaded and I quit the mission, next time I start the mission, everything is quick! Seems to be the transfer of the textures and shaders into VRAM. Something, we can't fix!

[@BumpyLumpy1]

I'm genuinely surprised how much this helped. i was actually gonna spend my night tweaking the settings/files after i got >10fps on a 2060 i-10600K 16gbs ram high settings.

[@Spudknocker]

Wow dude! That’s amazing! What a huge boost!

[@jaromirandel543]

After a lot of research, I came up with something. Probably no one should have this problem, but I'll share it just in case. The last update improved my 99% FPS percentile a lot. This probably caused my set limit of 60 FPS to be too low. Because of this, CPU usage was so low that it caused core parking, which caused the game to be choppy. Ironically, raising the FPS limit to 90 solved the problem because it forced the CPU to work harder and thus no core parking occurred, (MSI Ventus RTX 2080 Ti OC 11G, Core I9-13900KF) So if you have a weak graphics card but a strong CPU, turning off some CPU cores (affinity mask) may help. I recommend setting the FPS limit as close to the 99% FPS percentile as possible.

[@jaromirandel543]

Or maybe force core parking off via MSconfig. I am going to try that now.

[@jaromirandel543]

Yes. Forcing the disabling of core parking via MSconfig is also an option to solve the problem. But raising the FPS limit seems like a better solution to me.

[@nilo4ever]

I'm running an old system in win 10 and vr and it's been a horrible experience for a long time. This fix works wonders even in win 10. Its not perfect but atleast its playable for me now. It may not be the best solution securitywise in the long run but hopefully that will be fixed. Thanks a bunch for this, Spud!😉

[@777XGang]

@Spudknocker Add a good disclaimer about the risks. This might not necessarily be a huge risk for the average DCS user, but there is a risk nonetheless. I like you, but doubling down on this is just dumb. You should be more clear about the risks associated with doing this, instead of making it sound like a cure-all for DCS and potentially other games as well. DCS User Files might have a pretty safe community, but you don’t know with other games and mod websites. For anyone thinking of doing what he says in the video, make sure you actually understand the security risks before doing this. I’d agree that some people are being over dramatic about it, but come on man, at least add a good disclaimer instead of calling it the “Magic Fix.”

[@fossmarkluni]

The cure is often worse than the disease, so I wholeheartedly agree with you. Preferably disable Defender altogether via group policy. Dedicate the rig for simulator use, and use common sense. If paranoia hits hard, do scheduled scans or on-demand scans with a solid signature-based antivirus solution, or just use dual boot for risky stuff. There are, of course, other tweaks for a dedicated simulator rig, but real-time scans of any sorts are normally the worst offenders in any environment (for both clients and servers). Over the last 16 years, antivirus solutions have given me hundreds of hours of good income

I use Bitdefender and it takes over windows defender. It has a game mode which can be manually or automatically created for your favorite games. I picked Bitdefender for this reason and have no problems with it so far. The first time I had any kind of stutter was when 2.9 came out and I had TFAA selected in one of the many combinations we can try now. Still not sure about SSS as I haven't seen that black shadow issue I saw on another vid. Every once in a while I go right to the BIOS and check for a update and make sure xmp is selected and the bios has the right ram speed selected. Then I work my way down through the Nvidia control panel, the Bitdefender game mode selections and then to the game graphic settings. Always find something that got changed with a update or whatever. The best catch was the auto selected ram speed in the BIOS and a BIOS update along with the xmp boost. Especially with a new PC. To be honest I haven't looked at that for a while.

Same for me. It was an oculus fail. Thanks or following up.@@Munky332

[@richmickelsen3421]

Nice call Spud!

[@moiluck]

That works great and I’ve been running that for a year or so with no issues. Windows defender is like a virus itself and there should be an option to turning off that intrusive protection. I use the pc only for dcs and there is no external software running in, so there is no point for an antivirus that will slow down performance all the time looking for nothing

[@redtailpilot]

Which is why I permanently disabled it in the registry 😂 Nothing running on my PC but DCS. Disabled it over a year ago and haven't had an issue yet. Much better performance in DCS!

[@ParZIVal19D]

Menus are different now. Options under virus and threat protection not the same.

[@pizzaparty-r1c]

Dude, did you have an actual antivirus software? No exclusions option anywhere on my pc.

[@Red.Diffraction.Studio]

This is wierd, i never got any blurry textures problem in loadings and i got a very decent setup.. Why using Windows Defender tho? ESET is more efficient and i never had to exclude anything to "grind" my texture loadings...

[@Catinthehackmatrix]

No more room to update DCS anymore. Solution is now to move everything temp. from the CoreMods folder, to another drive until update done. Mostly had already moved the larger aircraft to another drive and was already using symbolic links for terrain and aircraft.

[@Dan-bv3cv]

When I click 'Add an exclusion', the windows security tab crashes and closes. Any one with this problem that has fixed it?

[@Mightymoose02]

Perfect timing. I have a similar system as you and am struggling with inconsistent performance. Will try your tips tonight!

[@CAPHOTO1961]

Im running windows 10, does this apply to this os as well? Thanks!

[@gabriel-bl4ckh4wk-6]

Thank u so much man!

[@Nilssen84]

Hey Spud! How can I change my savedgames folder from the windows drive to another drive?

[@jaromirandel543]

I was expecting the CPU core parking issue. Not this. :D CPU core parking issue is something that happens last time on many windows PC's. System forces cores to park even when they are needed. Fun part is for those who experience this issue, the ST runs better than MT. There is needed to manually turn off the core parking through the msconfig menu or via windows registry.

[@redtailpilot]

or just disable the E-cores in bios and live happily ever after in DCS multi-thread😂 (especially for VR)

[@jaromirandel543]

@@redtailpilot disabling E-cores will not solve problem with parking P-cores

[@redtailpilot]

@@jaromirandel543 True. I should've wrote "and"

[@redtailpilot]

@@jaromirandel543 BTW, I temporarily enabled my e-cores again to see if anything changed recently and the stuttering was unbearable. I disabled them again and DCS MT went back to buttery smooth performance. Cores are unparked

[@MarkiusFox]

I currently use an Oculus Quest 2, should I add that as well to the Defender exclusions?

[@Munky332]

Any pertinent software could probably help, ie TrackIR, SRS, Oculus, Steam/SteamVR, etc... just be warned, it *may* open you open to vulnerabilities.

[@GolddenWaffles]

I still use Windows 10, and this isn’t such a big deal but I’ll check it out 😊 thanks for the tip! I may be able to gain some fps!

[@IowanLawman]

If you've downloaded everything on Stream, wouldn't it work just as well?

[@vracan]

will this improve for win10 too?

[@Spudknocker]

Unknown for me I never had this issue in win 10

[@suecobandito8954]

Just found the same controls and implemented them in W10. We'll see.

[@coldwarriorUSAF]

Load times improved by at least 2/3 on my Windows 10 system. It also cut out the jitter, no FPS increase but smooth at 32-36 FPS in VR is good enough for me. Thanks Spud.

[@stevenkinney4536]

I spent hours trying to refine the 2.9 (and NVIDIA) settings but never could get the results I was expecting. I just tried this fix on Win10 and it resolved all my issues.

[@minghou5259]

I am wondering that the new machine does not have antivirus installed and it explains why Windows defender is on.

[@willm.n2178]

Hey sorry, what do you mean by 99th percentile?

[@Spudknocker]

Hey man so it’s basically a statistical measure that means that the FPS value is below 99% of other values

[@Freeway7]

So why not just Disable Anti-Virus when playing then ??

[@Spudknocker]

That should also work!

[@redtailpilot]

or disable it for good via the registry, like I did a year ago 🤣 (nothing on this PC but DCS, so I accept the risk. Haven't had a single issue yet).

[@ysiadpir1423]

Interesting.. OK.. I amusing Tobii but will do similar procedure..thanks Sir.

[@Spudknocker]

You can definitely do the same procedure with Tobii Eye Tracker!

[@brandonkasel4707]

I recently watched your video titled “The MAGIC FIX For Better Performance in DCS World 2.9!” and felt compelled to share some feedback. While I appreciate the effort you put into creating content, I must say that this tutorial falls short in several key areas, particularly due to its excessive descriptiveness. From the outset, the video is laden with an overwhelming amount of detail that ultimately detracts from its usefulness. It feels as though every minute aspect of the process is dissected to an unnecessary degree. Instead of providing a clear and concise guide, the video bombards viewers with superfluous information that only serves to muddle the core message. This level of detail might be beneficial for a handful of users, but for those seeking a straightforward solution, it becomes a frustrating barrier. For instance, when discussing the settings adjustments, the narrative dives into intricate technical jargon and step-by-step explanations that are not only redundant but also confusing. Rather than streamlining the tutorial to highlight the essential changes needed for performance improvements, the video seems more like an exhaustive manual on every conceivable setting in DCS World. This approach could be overwhelming for viewers who are simply looking for practical, actionable advice. Additionally, the video’s structure contributes to its lack of clarity. The lengthy explanations about each adjustment option create a convoluted experience where the main points get lost in a sea of details. It’s as if the video’s goal is to cover every possible aspect of the topic, rather than focusing on delivering a coherent and effective solution. This results in a presentation that feels disorganized and difficult to follow. In summary, while your commitment to detail is evident, it unfortunately makes the video less accessible to those who are searching for a clear and concise tutorial. A more streamlined approach that focuses on the most impactful changes and avoids excessive elaboration would greatly enhance the utility of the content. I hope this feedback is helpful and encourages a more focused approach in future videos.

[@raystrickland344]

Well ,I must say some get, It wasn't just produced for the book worms out there ! But thank you for your two cents . I must add why haven't you backed your views into action ?

[@lasselahti4056]

Hmm does windows 10 have also something like this?

[@spirosdelistavros2970]

but this is for if you only use defender, what about if you use norton????

[@zbeen-ah-lah]

So, when I get to the “virus and threat protection” page, it doesn’t show the “virus and threat protection settings” option for some odd reason, so it won’t let me exclude dcs from windows defender :( is there a way to do it on mcafee?

[@Spudknocker]

I’m sure there is I don’t use that software

[@_Zaid]

Yeah, uninstall mcaffee, it's a piece of junk

[@Fox3-Luck]

Great Video! I always disable Windows Defender and any other AV for games

[@Spudknocker]

Absolutely!
