Are you using the proprietary Nvidia or the Noveau drivers?

Start by changing to Nvidia's drivers if you are not already using them.

Yes, I'm using the proprietary Nvidia driver.

Try running the game with WINEDEBUG="" DXVK_LOG_LEVEL="" and see if any errors pop up in the terminal that give more information as to what's going on.

You could also try downloading a newer version of DXVK and updating it via the script's menus, or you can try playing using WineD3D instead if you set PROTON_USE_DXVK=0 when running the script (although in my experience NWN2 can have some rendering issues with that).
First make sure you have the latest Nvidia drivers installed, and that you're not missing any of Wine's dependencies that may be needed. Assuming that's the case, you could try downloading a newer version of DXVK and updating it through the script's menus (Advanced options --> Configure DXVK --> Install/update DXVK). If that doesn't work, try running the game with WINEDEBUG="" DXVK_LOG_LEVEL="" set and see if any errors pop up in the terminal that give more information.

Thanks for the info. I'm using the latest Nvidia drivers, and as far as I know, all dependencies are installed. Tried to update DXVK as well, but the prorblem remains. When starting in debug mode, I see these messages once the screen is messed up:
...
err: D3D11: CopySubresourceRegion: Incompatible texel size
err: Dst texel size: 8
err: Src texel size: 4
err: D3D11: CopySubresourceRegion: Incompatible texel size

Thanks to novumZ gifting me a key for it, a wrapper is now available for Cyberpunk 2077. And the DRM'ed "My Rewards" bonus items should be unlocked by default without requiring any online activation :)

Some notes:

* For now, patches need to be installed manually as they work differently to patches for other games on GOG & I can't automate them. To do this, run the patch installers by either selecing "Advanced options..." --> "Run..." in the script's menus then selecting the patch installer & clicking through, or by running the start script with: ./start.sh runwine : "/path/to/patch/installer.exe"

* I have found that the game sometimes crashes on startup & needs to be killed (use "./start.sh kill")

* For now this is best played on systems with AMD graphics cards using the open drivers. Make sure you have the latest available kernel and either the latest development release of Mesa or the Mesa builds from Kisak's PPA (if you're on Ubuntu/Mint/other Ubuntu-based distro). If you have an Nvidia GPU expect frequent GPU hangs rendering the game unplayable.

* Sound may crackle. It may be fixed by running the game with: PULSE_LATENCY_MSEC=60

* Spatial sound doesn't work, making a lot of sound effects near silent.

The above two issues are apparently fixed in the current experimental Proton build, but unfortunately it looks like the newer Proton builds can't be used independently of Steam any more. I'll need to investigate & see if I can manage to work around this compiling Proton myself again, but it may take a while as I haven't checked up on it for quite some time. If not, then hopefully Wine / Wine Staging 6.1 will include the necessary fixes.

It looks like a GPU/driver issue to me. The game runs fine on my system and I don't get those errors, but I use an AMD RX480 with the open drivers. Unfortunately I don't have access to an Nvidia system to test right now.

I've always run NWN2 on Wine Staging without DXVK and never had a problem.
Might that not be easier?

Hopefully GloriousEggroll will come out with an updated Proton-GE build soon.

Hi,

My bad if this is considered necroing the thread. I was just wondering if I could in any way aid in the development of a wrapper for IL-2 1946?

Wanted to say thanks to adamhm and everyone else posting here for these post and scripts. My wife and I have been picking some more wine based games (usually stick to Linux native). She ended Dead Space last night and was so very delight with how easy it was to install on her rig and on the living room HTPC.

Will there be a working version of this for Mint 20.1?
It's not working as it is on the current version of Mint.

Ive tried out linux gaming yesterday , still garbage as it was a year ago.
Manjaro + proton GE latest.
Steam has problem running win games not from the main partition, needed tweeking...
Fallout 76 is producing way fewer fps than on win10.
Imho this linux gaming is going nowhere. Does steam still developing it ?

PEBKAC

typical linux fanboy...
your shitty os is just crap

Do you have an Nvidia GPU? Sadly Nvidia's Linux drivers are quite a bit slower.

Windows games are made for Windows so for new games it IS quite natural that they work better and are easier to install on Windows. adamhm has been so kind to make some Windows games work more easily on Linux in cases where they are not quite install and play away.

nah amd rx 580 manjaro installed its driver by default
protondb recommended a slightly different driver, i havent installed that one , probably wouldnt change a bit

yeah his work is good , still i just wanted to test some games i play recently , Hunt wouldn't even run as it requires anticheat not supported by linux yet , and Fallout 76, but i got low fps with that
tried out linux native Dirt 4, it ran well as expected
