Prototype 2 terrible performance on Steam Deck LCD (Windows)
Software information
Prototype 2, latest stable DXVK version, default settings
System information
GPU: AMD Custom GPU 0405 Driver: Valve official driver Windows version: official 10 22H2
Feels like 1-7 FPS, i experience terrible lags even in the menu and game is completely unplayable
https://www.protondb.com/app/115320 not that these reports inspire much confidence, but this doesn't seem to be a problem on Linux?
In which case this is clearly not a DXVK issue. One thing you can try is setting dxgi.hideAmdGpu = True in a config file to see if the game is trying to initialize amdags thousands of times per frame or something (we've seen that before), but those kinds of issues are entirely expected on Windows.

prototype2_d3d9.log Here's the log from Windows. Also without DXVK i get 10-27 FPS, with DXVK - 1-7 FPS On Linux the game can't even start, it crashes immediately after pressing Play button in Steam
Driver is throwing VK_ERROR_UNKNOWN, which... yeah. Can't really do much about that on a driver that seemingly hasn't been updated in almost two years.
I am also not seeing any issues when trying to start it on my LCD Steam Deck with SteamOS. Both stable proton and experimental starts the game fine. Performance have been a stable 60fps for the little while i played. 800p and high settings.

But my Steam Deck LCD can't even launch this game on Steam OS... When i press Play button it crashes immediately, i already tried all solutions i found and nothing worked
Running the game with PROTON_LOG=1 %command% in the launch options should make a log appear in your users home folder on the Deck.
I remembered now that the Windows issue is a general problem with a bunch of games when using AMDs Windows driver and dxvk https://github.com/doitsujin/dxvk/issues/4730#issuecomment-2697595425
