Without GE proton, I launch this game, then as you can see in this recording the screen is totally black but it has actual game audio runs in the background. I tried with GE proton, 8-25,24,23, and experimental version, but none of them works, they all have the same problem. I also tried reboot SD, still doesn’t work.
I know this game is running in the background but the screen just shows nothing. When I switch to the desktop model, I can play horizon 4 without any problem. I believe it should be some software problem with the oled version. Becasue I also have a lcd SD with the same latest Steam OS 3.5.7 and the lcd SD has no problem when playing horizon 4.
Hope anyone can help me on this issue. Thanks.
Start the game in desktop mode. Turn off full screen in video settings. After changes have been saved, it should work in game mode.
You are my hero of today! It works! Thank you!
