Hi,

these crashes are likely caused by the GPU running out of memory or by faulty drivers. This [Content removed] contains a potential workaround to prevent the GPU from exceeding its memory budget while compiling shaders. Could you please try the following settings:

D3D12.PSOPrecache.KeepLowLevel=false
D3D12.PSO.KeepUsedPSOsInLowLevelCache=false
r.PSOPrecache.KeepInMemoryUntilUsed=0 (if UE 5.5 or UE 5.6) or 2 (UE 5.7+)

It would also be helpful if you could share the shader assembly that was dumped when the PSO compilation occurred, as mentioned [Content removed]

Can you provide more details on the type of GPU you are using? Do the crashes happen randomly or do you have reliable repro steps that trigger the crash?

Thanks,

Sam
