Plays decently, though with frequent magnifier use in menus. As with most UE4 games on Deck, performance and battery life aren't great.
45 FPS cap
Race UI is clear but many menu elements aren't, especially button icons.
Installed DLL detailed earlier in the thread
With the DLL detailed earlier in the thread, the game runs better than native. The controller support is perfect.
GloriousEggroll Proton-6.8-GE-1 GloriousEggroll
Just use GloriousEggroll Proton-6.8-GE-1 and the game will start I also put the D3DCompiler_47.dll on "~/steamapps/common/MXGP 2019 - The Official Motocross Videogame/mxgp5/Binaries/Win64/" don't know if this helped too, do both just to be sure, i used the version 10.0.15063.0 64bit of the dll
The game only let you alt-tab when you select windowed mode from the options, same as on Windows
The game will stutter and locks up for for 1-2 seconds sometimes because of shader compilation each time you enter a new race, after that it's smooth
Gets a fatal error alert box when trying to run
I tried SLR, proton 5.0-9 and 4.11.-3 none worked. Tried the modification specified by user baggiox:
Download the DLL D3DCompiler_47.dll from here (version 10.0.15063.0 worked for me) Place the dll in ~/.steam/steam/steamapps/common/MXGP 2019 - The Official Motocross Videogame/mxgp5/Binaries/Win64/
And tried it again on 5.0-9 but it didn't make a difference.
Fatal Error upon launch
