IN DCS WORLD YOU NEED THE "BEST" FPS, Not the HIGHEST! - Why you need to cap or limit your FPS now!

[@jakefowler8522]

Your eyes don’t see in fps. Also, you totally can see the difference between 30/60/120+ fps. You are however correct that latency issues will cause stutters. And limiting fps to reduce that problem does work. Depending on the system you run and in game settings etc.

[@kzrlgo]

This is a great tip! I’ve been trying to tell people about this. Steady frames are better than peaking slightly higher.

[@AIRWARFAREGROUP]

[@TheSkilledballplaya]

i hope all FPS chasers realize this..A 60 Hz monitor basically refreshes the panel 60 times every second, which is basically 60 frames per second. So even if hardware capable of higher frame rates is plugged into a 60Hz monitor, the monitor output will be capped at 60FPS

[@AIRWARFAREGROUP]

👍Remember the days of screen tearing...wonder if that is still an issue these days with the new tech.

[@aviationrambler]

I think there's a lack of understanding here. Decreasing frame rate fundamentally increases latency simply because of reduced input calculations and fewer visual updates being sent to the monitor. What you're fighting is frame pacing, in other words the timing between each frame. For example, at 60Hz, assuming all frames are evenly paced, you're looking at 16.6ms of latency (assuming the physics engine, monitor, and input devices are updating at or above the FPS value). Increasing to 120fps halves the latency value. That stutter with the P-51 taking off could be due to a number of factors such as hitching (where a critical operation prevents execution of other operations because those operations require the vales obtained from the critical operation) induced by the server connection or asset loading. Honestly at the frame rates stated, you're likely to see an FPS drop at that point where the stutter was present, even at 120fps. In fact I know you will because it was jarring for me even on a 60Hz monitor. In the event you're seeing stutters but fps is not dropping, the frame pacing is inconsistent. In other words you're getting some frames close to each other and others farther from each other, but the total number of frames is still the same in that second of measurement. Now, at 1:28, it's stated "When you cap your fps, you're basically reducing the amount of latency that occurs when you have FPS drops and rises." I feel like this is unknowingly alluding to the problem when inconsistent clock speeds of the GPU/CPU. For the most consistent experience, maximum clock speeds are preferred at all times, altho this does increase power consumption which is up to anyone who reads this if that matters if that matters to them. In the event your fps drops, yes latency will increase due to having less frames. However, in the event the GPU/CPU is at a lower clock speed and the workload increases, it's far more likely to fall behind the work load, and this will lead to those kind of of stuttering as shown, and by extension an even larger drop in frame rate. TL;DR I do not think capping your FPS is going to do anything for that stutter that was shown, unless you're playing at like 15fps. It's likely hardware issues. IE Server not keeping up, CPU/GPU clock speeds not ramping up clocks fast enough to deal with that panning camera, or perhaps the hardware struggling to load in and process the assets for the game. PS There is one use case where capping FPS would decrease latency and that's inconsistent frame rate below the maximum refresh rate of your monitor if you're using Gsync or Freesync. This still doesn't fix that stuttering shown in the video however. Hope this helps.

Thanks for getting the word out on this. I tell folks in my sphere that with regard to frame rates, you shouldn't apply the same logic to a flight sim as you would to a quick-twitch shooter. It's a different animal entirely. A consistent frame rate is way more important than maximum FPS.

Having a solid constant fps also helps with spotting in DCS. Often even a slight dip in fps can cause you to quickly lose sight of the bandit, especially in ground clutter.

MavicAir1, thanks for your input! I'm at 90 and it's running better than when I maxed it out at 144. I still get negative feedback from guys who haven't experienced what it really does for us. That lag time when the machine pushes to the max and shutters when frames dip is what we're avoiding. I could run 100, 120, probably with no real issues for the most part, but 90 gives me the same experience as those settings but as you said, with way more cooling and less stress on the GPU/CPU.

If you can fly for a while with the FPS monitor on (click the little triangle to make it minimal) you could see how much it goes up and down...and if it seems to float between say 60 and 90 set it for 70 or 75 to see what happens. Then for giggles, set it to 60 and see if there are any hick-ups. There will be some when someone loads into the server, when you take screenshots, or something like if you have your preload radius set too low, all of a sudden a lot of detail has to POP into render. I am going to chat with Ben of ED this week or next about setting a gradual preload function or if such a capability exist so that as you approach a town or area with detail, such things as buildings come in first, then vegetation, then vehicles, objects, etc. I am not that smart on this stuff on the coding level, but it seems to me if you pour too much liquid into a funnel, it will spill over and cause problems. But if you pour in a little at a time, you get a smooth stream of transferrable volume. Did any of this make sense?? LOL

[@byronswart7017]

I have mine capped at 60fps for silky smooth performance at max settings with everything turned on. 👌 DCS looks absolutely stunning and feels solid and fluid compared to being uncapped and having the frame rate varying. Why 60 fps? I my eyes can’t tell the difference between 120 or 60 fps. At 120 fps you I can definitely tell if I get a sudden drop to 115 fps on a flyby for or though a dense city example. My monitor refresh rate is at 60hz, and producing frames above 60fps would be something my monitor can’t display and would be a waste of GPU resources. For me it’s better to have all the eye candy turned on and fly at a solid 60 fps than tuning things down to get higher frames and for what? A solid and sustainable max frame rate has always been the holy grail for flight simulation. Why people waste their time trying to achieve max fps that varies constantly is beyond me. If you say but, I get good frame rate between 120 and 80, yes that’s great but you will still have jumpy game play that’s noticeable to the eye and that will kill your immersion a little. Give it a try guys, you can always uncap it if you don’t like it. 😊

[@alexsachse]

I play DCS in VR with my Pimex Crystal (using 4090), and up until yesterday I used 90 Hertz refresh rate with eye tracking and DFR and locked my frame rate in the Pimax XR software to half of that. Since yesterday when the firmware update came out, I'm using 72 hz refresh rate and full frame rate. Butter smooth VR experience without stutters at all at low level flights over Normandy map with P-47. Likewise, no stutters when flying the AH 64D over Persian gulf, Syria, or Caucasus maps. So, I've become a big fan of locking at half the frame rate while running ultra settings in-sim.

[@AIRWARFAREGROUP]

That's awesome, and if I read you correctly, you saw improvements?

[@alexsachse]

​​@@AIRWARFAREGROUPYes sir. Visual improvements in terms of elimination of stuttering. Locking in half the frame rate at 90 Hertz didn't result in a diminished picture quality, I want to be clear about that. Like you said, most people cannot recognize additional frames per second beyond 60 to 70 hz. And I find that to be true for me for sure. Therefore a solid 45 frames per second in 4K in VR is worth a lot more than 120 frames per second if it don't get a butter smooth experience, and I'm constantly reminded that I'm actually in VR.

The most optimal framerate (performance permitting) for eyes is 90. Anything in VR under 90fps will add to motion sickness. Eyes can definitely perceive a difference between 30-60 and for many people 60 - 90. After 90 extremely few people could tell you a difference (though many will claim they can) though this is not to say our brains are not affected in maybe a similar fashion to fluorescent tube lighting; which affects the brain but not our vision. Though again anything above 60-90 is a waste of PC performance that can be put to better use. Hopefully FSR 3 with frame generation will smooth things out for those of us lacking ahh in performance in the future.

Quick question, I’ve limited my frames through vsync and also Nvidia control panel to 60. I still get stutters on a couple of maps and when I loon at the fps counter it’s the frame time causing it. The fps in the top part are well above 60 but the frame time means I then drop below. Am I misreading the fps counter and it’s some sort of theoretical fps if my cpu wasn’t limiting frames? Seems to happen over dense scenery.
