Hello there @4282775
Having also experienced the full new rig setup, only for weird issues to pop up, when the old equipment was doing just fine, I know it’s a very frustating scenario. Now, since you moved the project from the old rig, the most likely cause here is that some files tied to the previous enviroment are creating conflicts.
So, the first step would be to fully clear the projec’s cache, via deleting the following elements, from the main directory:
- Delete “Intermediate” folder
- Delete “Saved/ShaderDebugInfo” folder
- Delete “DerivedDataCache” folder
Then, from Engine, go to Edit, Project Settings, Rendering, and find/delete all cached shaders.
After these steps, we also need to make sure that your current drivers are up to the task in the new system. For that, open nVidia manager (or Experience), download the “Developer” drivers, and pick the “Clean Install” option when making the setup.
This should clear your environment completely, now please test your project, in both DX11 and DX12. If more issues pop up, test one more thing, run your project without VSM:
- Go to Project Settings, Rendering, Virtual Shadow Maps
- Uncheck “Enable virtual shadow maps”
- Restart the editor
Hope this helps!
