But somehow having it running on Win11 build 22000.675 will always cause Unity games to crash, I don't understand why. If I terminate the DisplayFusion process, no more crashes for my game.ĭisplayFusion itself works fine, no crashes. Tested multiple times and the behaviour is consistent.

However, if I install DisplayFusion (latest beta) and let it run, after a few hours my game will crash. The Win11 build I'm running is 22000.675. On a brand new install of Win11 with the latest cumulative update applied, I can run my Unity game for hours and hours (at least 8 hours non-stop) without any issues. OK, after many many hours of testing, I've come to the conclusion that there is something wrong with. This leads me to believe that DisplayFusion on Win11 seems to be doing something differently and causes apps in the background, specifically ones that use Unity. Same issue.įinally, I just terminated the DisplayFusion process completely and the game runs fine for hours. I then added the game to the Compatibility list and disabled all the DisplayFusion features. I then did another test, where I disable all the DisplayFusion settings, same issue. When I tested running DisplayFusion on Win11, I tested by doing a completely uninstall and reinstall and only loaded the license key and nothing else. On Win10, I can run the game and DisplayFusion at the same time. However, this is only a problem for DisplayFusion on Win11. If I run DisplayFusion, it causes the games to crash. If I don't run DisplayFusion, my games run fine. No issues.Īfter a lot of testing and trial and error, I found out that it was DisplayFusion causing the issue. But then I installed a fresh Win11 on 2 different laptops and ran the same game on both of them for hours (more than 8 hours). Initially, I thought it was a Win11 issue. I've done a lot of troubleshooting on this error and tried a lot of things.

The games are made using Unity and the crash error is always the same - UnityPlayer.dll Access Violation - 0xc0000005. I've noticed that on machines that are on Win11 (build 22000.613), my games seem to always crash after running for about 30 mins ~ 1 hour. On all the machines, I run the same app and games. All of them run the latest DisplayFusion (always). I have multiple machines at home, some are running Win10, some are running Win11. I'm using the latest DisplayFusion beta 15 (as of this writing) and I'm noticing something weird on Win11.
