NVIDIA-open drivers on Linux Loses some Performance VS windows with IPC intensive games!

[@pip5528]

I noticed that CachyOS fixed its weird bottlenecking recently so I'm happy about that but it's a shame this happened. It's easy to say to just go with AMD (I have both brands at this point and can attest to its comparative seamlessness) but I want Nvidia to continue to improve so that the brand won't matter on Linux. It matters less than it used to. I am certainly of the opinion that most of the Nvidia hate on Linux is outdated, though I do think the cards themselves are becoming overpriced regardless of OS. General usage and Wayland support are really good now but there are still some kinks.

[@michaell.8748]

It looks very similar to the performance regression you get with DX12 with nvidia on Linux

[@JamerTheProgrammer]

Experienced similar issues even with the UI of KDE on Bazzite. The fix was to rebase to the Nvidia legacy image of bazzite and disable GSP

[@terratrodder]

I have had great performance for the last year on my nVidia 4060 (laptop) but the last couple of months something changed. Not sure if it was a particular update but after about a half hour to an hour everything gets studdery like I'm losing frames. It doesn't recover and I need to fully close the game.

[@ml_serenity]

There is a case of VRAM leaks in DX12 games with nVidia. Especially pronounced in D4. There are workarounds, though. Check on protondb

[@iBolski]

I've noticed this as well and I'm just running a lowly GTX-1660. Before that, performance was pretty much on-par with Windows. But in the last couple of months, I started seeing performance tank in many games that were fine before. Booting into Windows and trying the games there, I saw an improvement to what I expected it to be. So something has changed and I think it's the nVidia drivers. My GTX-1660 still works fine for the games I play, so I don't have a reason to upgrade at this time. I normally don't upgrade every change I have. I pretty much run my hardware into the ground before I upgrade again. 😆

Vram issues

[@DavidCoutinhoCG]

i literally got the same results, i've tried ryujinx and suyu with my RTX 2060 and my Ryzen Vega from my 5700G, and the 5700G gave me better results than my RTX 2060.

[@Mattscreative]

Report that on the 565 driver forum for Linux please

[@Zaxth]

I see the same issue on my system with a 4090. CachyOS on the Linux side with both with the bore scheduler and with the eevdf scheduler. Windows 11 (24h2 LTSC) generally performs a lot better than Linux. With more stable FPS and lower frame times. I even setup a virtual windows machine under Linux with gpu passthrough, so that the scheduler was dictated by the Linux scheduler, and it was the same story on the virtual machine. So that rules out the scheduler's and the kernel. It's 100% something to do with nvidia.

[@Mattscreative]

Report it please on the 565 driver forum

[@Zaxth]

@@Mattscreative You got it, done.

[@radvilardian740]

stupid fact for is most of these fps drop and laggy issue on steam games all get fixed itself once i run steam in big picture mode, idk why. Now it is so much enjoyable to play. After weeks doing that, decided to completely remove my dual booted windows and install it in a separate drive just in case i will need it again.

[@Mattscreative]

@@radvilardian740 that's not a fix

[@Wkaelx]

I think big picture uses the Valve's gamescope compositor, I've seem a lot of cases where it solved problems related to stutter and frame drops, still not sure though.

[@starblursd]

dang... makes me concerned a bit about my switch to linux. im on a 3080ti and dont have the money to switch to amd rn especially being in the US rn. i can only hope that nvidia fixes their drivers which is honestly the only thing i can think of that wouldve caused this. cause im pretty sure performance was better than this a month or two ago

[@Mattscreative]

it's only in 10 games plus the reason for the video is to bring notice and have it fixed so you will be fine.

[@starblursd]

@Mattscreative that's good... Im too busy breaking and fixing network manager anyways... Protonvpn probs

[@IvarsRuza]

About 1 week ago drastic frame rate drop hapend to me. Im using Cacheyos, amd gpu and amd card. All i did update the system. There were kernel and mesa updates. Also i dont know why but something droped my wine-ge for lutris. So i reinstalled wine-ge for lutris and wow was playable again but the frame rate was down, way down.

[@MikeDawson1]

did you try switching to the closed 565 version instead of open? (and disabling GSP)

[@Mattscreative]

Both are the same

[@glenni83]

I think maybe this issue was introduced with the 565 driver. Then the older 560 driver dont have this issue. We where talking about it yesterday on discord. Test it. We have had a lot of CachyOs people reporting major issues around gaming now past weeks. My self has issues as well, so I have pretty much giving up on the gaming side of linux right now. Why I still have Windows.

[@Mattscreative]

Tried 555 and 560 and 565 all the same

[@glenni83]

@@Mattscreative ok, might be wrong what they report. Strange part from time to time. I can see the same, where people say its working. It was from Airmax stream the other day. Then on my system its not working at all. That is when things start to get frustrating. But you are right about what you see. I have noticed a huge issue my self around dx12 and vulkan. I had 1 year of benchmarks from windows and linux, I was monitoring, that did go up in smoke last week, while I installed PikaOs 4.0. When PikaOs was installed it deleted my EFI partition. Then moved the efi to the pikaos drive. So I had 8TB data loss. I have spoken to arch devs and the devs over at pikaos. So I have an idea what was going on. Sadly, now i cant provide you with the benchmarks that I had from both systems. But I have seen the changes over time. I also been reporting back to nvidia. But not a word back Im a huge emulator guy my self, with a retro collection on close to 110k games. But Switch emulation has been difficult in performance on linux now. I doubt it has anything to do with emulator it self in linux. Due my old setting for a high end spec, is not usable anymore.

[@linuxbenchmark9036]

Frame Generation with AMD isn't very good on Cyberpunk either; it added overhead. I believe features that heavily rely on Windows components will take much longer to catch up with the graphics stack on Linux.

[@Mattscreative]

not that long should be finished soon

[@Wkaelx]

Frame Generation on itself isn't very good.

[@JaredX7]

Did you know your camera/webcam has a audio sync issue though? I would add a video delay filter to the source in obs to make the audio in sync.

[@Mattscreative]

yes i know it's just a pain to fix

[@JaredX7]

Actually, the voice is played too early. So you'd need to add a delay to the microphone audio track instead.

[@JaredX7]

Scratch that, I was right the first time. I can't edit or delete my own comments on my phone.

[@Seven_Actual]

My general experience since switching is everything feels better on Linux with an AMD card. Even if the numbers aren't better the gameplay just feels smoother. With my Nvidia card it has been the polar opposite. Every distro and every game. Even if the game plays excellent it won't "feel" as responsive to the player. I just shelved my Nvidia card. The AMD experience is so far ahead on Linux honestly. Even little things like waking up after sleep Nvidia blackscreens every time.

[@Mattscreative]

@@Seven_Actual not had that at all with Nvidia just 10 games where having issues

[@Seven_Actual]

@@Mattscreative I've not found a single game where the performance on Windows isn't at least somewhat better than Linux with Nvidia. Not always a lot of depreciation but always some. With AMD it's either the same or better performance on Linux almost without exception.

[@Mattscreative]

@@Seven_Actual every single title minus 10

[@gerarderloper]

NVIDIA doesn't watch YT. Really the only way to get attention is to present hard evidence on their issue forums. They seem to be active on there even if they don't respond too often.

[@Mattscreative]

i sent the video to an nvidia dev i know

[@Pieteros21]

I had to much issues with gtx1080 on both windows and Linux so I now have a Radeon 7900gre and for me performance is rather similar in most games , except ray tracing is either crashing game ( control ) or giving half of the windows performance at best ( witcher 3 ) . I am using fedora 40 with latest updates . Will switch to fedora 41 soon .

[@Mattscreative]

GTX 1080 has always been wonky on li ux due to a lack of hardware features for vulkan

[@Pieteros21]

@Mattscreative I have dual screen setup - 32inch 1440p@165hz and 24inch 1080p 60hz in pivot and on some driver versions when my main screen was playing video and I moved cursor to another the main monitor would flicker or even turn off for a second od two . To be fair on windows this was also happening but was fixed way sooner . I wasn't only issues I had but most annoying probably .

[@PavlokK]

Does this problem still exist?

[@Mattscreative]

Sadly yes but easy to avoid use the closed drivers

[@PavlokK]

@ And what is the case with dlss and with FG? Because I've heard that it started working with Proton Ex, and I'm not hiding that it's the only thing stopping me from switching to Linux

[@laitinlok1]

@@laitinlok1 i will try it but if it doesn't work !! I will shake a stick at a cloud

[@OraOraOra]

I know.. you are burned out, but: You cam is really good! Fresh beard, eyebrows and hair and blueeeeeee eyes. And it really sucks... I hope that will get fixed. I heard that proton experimental fixes some Nvidia related stuff, but obv. that doesn't help with your Emus. Yeah and because you asked for others experiences: I'm also dualbooting atm, cemu has massive problems with the current AMD Drivers on Windows. Botw won't even launch. But overall the performance is the same on Linux vs Windows, sometimes even better! Buuut Raytracing on Linux is much worse compared to Windows, but let's be honest, who gets an AMD Card for Raytracing :D

[@Mattscreative]

i just looks like this all the time lol also ya i hope it will get fixed also and cemu has always been fine it's ipc intensive emulators and pc games i need results for

[@smashpro1]

Bold to show Nintendo emulation, given how hard they are going after that with DMCA takedowns.

Already checked I'm fine

Pls compare darktide and other games.

X11 vs Wayland?

[@alexcerzea]

Wayland is the go, x11 is getting deprecated from gnome and kde, the only ones still using them are some rare TWM 😅

@@alexcerzea Thank you, npc bot, but that wasn't my question.

[@KajzerD]

@@alexcerzea Still not way to go. 1% lows and min fps is trash on Wayland. I still run X11 on KDE until it gets sorted out (AMD gpu). Input lag is also more noticable when you limit fps on Wayland. Global hotkeys are overall garbage, some apps just refuse to work with Wayland. I could go on but it's pointless. Wayland is not ready yet

[@alexcerzea]

Yo don't need to insult dude

[@alexcerzea]

@@KajzerD Rare, I didn't got most of those issues in my Nvidia GPU laptop, the only one was that the gpu sometimes wasn't being taken by the games, due to my setup being an optimus based laptop

i prefer nvidia because of DLSS, but im not stupid and know nvidia has issues on linux... i definately think depending on the 8000 series launches raytracing capeabilities i might just grab an amd gpu as sad as that sounds.

This kind of dumb performance crap is why I still use Windows for gaming. It's just not worth the hassle dealing with gaming on Linux, especially with Nvidia. I hope some day it gets to the point where it just works as well as the Steam Deck.
