What is your CPU, GPU, kernel and GPU driver ? What version of Wine are you using ? Have you enabled DXVK or VKD3D yet ? You say you're using the non Steam version, what does that mean ? Epic Store or something ? What frame rate were you getting on Windows and what are you getting on Linux ?

One thing I will mention from my experience is that Lutris sometimes has issues with using Esync and Fsync which are features that can improve framerate depending on the game. I would recommend trying Heroic Games Launcher as they have never given me trouble using those features.

Hello, thank you for your answer.
Here is my system information:
CPU: i3 2100
GPU & driver: Nvidia GT 430, 390.157 (proprietary)
Ubuntu version: 20.04.6
Kernel version: 5.15.0-101-generic
Wine: wine-9.0 is installed on my pc, also tried lutris-fshack-6.21-6 (found this one works the best) and tried a couple of older wine versions provided by lutris.
I did not enable DXVK or VKD3D because my drivers are not supported and i can't use those features.
By non-steam i meant downloaded the patched game from the internet.
With this hardware i was getting minimum 100 fps on windows and max over 150, on linux i get minimum around 40, max around 100 (and that is when i turn my head by the wall and not doing anything).
I will try Heroic Games Launcher and post the results when i do that. Thanks again for helping.

Wasn't CoD4 OpenGL? If so, DXVK wouldn't make a difference anyway.

Thanks for the info. I was worried you might be using out of date stuff such as a really old version of Wine or something but everything seems fine. I Might be able to test the Steam version in the next few days. If so I will try it on both my onboard Intel GPU as well as my RX 590 and see what kind of performance I get as a comparison.

Been many years since I played a MW game so I wasn't sure.

That would be great, whenever you have time do that test and post the results here.
Thank you very much!

According to [PCGamingWiki](https://www.pcgamingwiki.com/wiki/Call_of_Duty_4:_Modern_Warfare#API) it uses DirectX 9.0c on Windows and OpenGL on MacOS. Unless I looked up the wrong game I get confused at COD titles as they sometimes repeat.

Absolutely correct. Also on early nVidia GPUs (I myself have a GT 730M in one of my still active systems) [Vulkan performance was not that good anyway](https://www.youtube.com/watch?v=Vf7_Xk0Ayxo).

However the downside of this is you have to use WineD3D which is known for having some noticeable performance regression even on older games.

For example: https://youtu.be/_uZD5yBwMzk?feature=shared&t=153

Unfortunately I do not own CoD4 any more to counter test this on my Laptop which is only one Intel CPU generation more recent than your hardare (i5-3230M + GT 730M). I once had a "backup copy" from a friend but that one got lost.
