following the most recent Proton guide on how to get it up and running but im still doing something wrong, the guide itself feels alittle lackluster but that may be just my inexperience with using Heroic, if anybodies got alittle time id like to share my screen and someone help me through the process.
proton guide said: "Got the game on GOG, installed via Heroic. Using "run exe on prefix" to install the unofficial patch. Set "alternative exe to run" to Loader.exe and it works great with Wine-GE-Proton7-43. After loading a save the game sometimes freezes. Pressing ESC to go to the menu and back into the game fixes it. In enabled both Esync and Fsync. MangoHud seems to work but it locks the cursor to the upper left for me for some reason"
