Working on an Unreal 5.1.1 project for almost 4 months now when suddenly the editor has begun freezing after just a few seconds. I’ve found the following:
Works fine with older Unreal projects (specifically 5.0.3)
Works fine with a different 5.1.1 project which is just an asset pack demo with no blueprints
Freezes with ANOTHER 5.1.1 project that used to work, noticeably contains blueprints and animations and such
Uninstalling and reinstalling 5.1.1 doesn’t seem to have affected anything
OK a day later the issue seems to be resolved? I tried rolling back my nvidia graphics drivers last night, and maybe it took a restart for the driver change to have any effect?
Not 100% sure but I’m leaving this here, I’m pretty sure the graphics drivers were the problem as I found this line at the bottom of my saved logs:
[2023.06.22-18.38.21:971][ 0]LogD3D12RHI: Warning: GPU timeout: A payload (0x0000049FA5100700) on the [0x0000049F9D812280, 3D] queue has not completed after 5.000144 seconds.
