In UE 5.6, if my projet as been open for few minutes (like 15), having a AnimMontage Tab open will make the App crash and few other case, with the error GPU :
UnrealEditor_D3D11RHI
UnrealEditor_RenderCore
UnrealEditor_Core
Some time the screen isnt working at its best after. My CPU is 7800x3D, and my GPU RX 7600, I Might be thinking its the GPU that for some reason cant follow since its the one that crash, but i was also wondering if it was because of 5.6, because my other problem with RHI directx12 on 5.6 wasnt present on 5.1
Hello there!
Yeah, that crash error is related to rendering processes, which confirms something’s going on between UE and the GPU. Following other cases from the community, there are a few angles to tackle this:
Considering no major changes were made in your setup, it could be just a matter of granting more leeway to the GPU. You can increase TDR in your system, which will prevent your OS from thinking the GPU has stopped respondering. To do so, go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers in your Registry, and edit the following two DWORD (32-bit) values:
- TdrDelay: set the Base to Decimal and the Value to 60 seconds (or 120 if it’s already in 60)
- TdrDdiDelay: set the Base to Decimal and the Value to 60 seconds (or 120 if it’s already in 60)
The next consideration, is to test UE with DX11, making your setup a bit more stable. Simply open UE with the -d3d11 tag in its shortcut. Following this line, disable any active overlays in your system, as there’s a surprising number of scenarios where they interfiere (stuff like XBOX Game Bard, Discord Overlay, etc).
Now, engine wise, one check that always helps is clearing the cache, to rule out stale or corrupted data. To do so, navigate to your project’s directory, and delete folders DerivedDataCache and Intermediate. After that, re-open your project and allow it to rebuild its shaders. You can also double-check your current install from the epic launcher, just check the dropdown menu next to the version, and select “Verify”.
im already using DX11 for the Rhi because the window was not fluid with the 12 in 5.6 (was in 5.1), the path you gave me, i couldnt find such TdrDelays or TdrDdiDelay, there almost nothing running in the back ground when i do it (discord,razer synape, msi center, vanguard) ill test to remove the cache and verify
