RX 6800 (16gb vram) running out of video memory way more frequently than with RTX 2070 Super (8gb vram)

[Koalakalle]

I bought a Radeon RX 6800 (16 gb vram) because I wanted more video memory. My previous card is a Geforce RTX 2070 Super (8 gb vram). With the RX 6800 I get crashes frequently due to running out of video memory, between 1-3 times a day if I work with Unreal engine for 8 hours a day. When I had the RTX 2070 Super the same situation happened rarely. Perhaps once every twice week. How come it is like that? I have’nt changed any settings in Unreal engine after the switch so this whole situation is very peculiar. The only reason I “upgraded” to RX 6800 was for the increased video memory.

Anyone else having the same issue??

Same issue here. I’m running the same card and I’ve been getting this error either while halfway working in the engine, or even while opening a project file:

When you encounter crashes, is this what appears in your UE5 crash UI?

I found a fix that worked for me:

GPU crashed or D3D device removed error

I recently encountered a similar error. Perhaps this will help solve the problem. Try deleting the project cache that Unreal Engine uses for temporary files. These are folders such as “DerivedDataCache”, “Intermediate” and “Saved”. Delete them, or move the folder to another location. When opening the project they will be restored. First, in the DefaultEngine.ini settings you need to set the desired DirectX value. [/Script/WindowsTargetPlatform.WindowsTargetSettings] DefaultGraphicsRHI=Defau…

Only drawback is everytime you open the project file, you have to delete the same three cache folders if not the GPU crash error will pop up again. But you do get to keep the DX12 and Hardware Ray Tracing settings turned on.
