Below are the steps to delete DirectX shader cache from a Windows 10 computer. Execution divergence occurs when different threads execute different shaders or branches within a shader. Applying SER allows the path tracer to reduce divergence in its material evaluation, instead of just on the number of bounces. Built on the 250 nm process, and based on the NV5 graphics processor, in its Riva TNT2 variant, the card supports DirectX 6.0. I'm using a SN750 NVME. This is how you change the Shader Cache Settings via NVIDIA Control Panel: There are specific predefined values that PC users can choose from. Apparently the stock shader cache for a lot of Nvidia cards is only set at 256MB, and this game uses a very heavy shader cache so setting the shader cache to 10GB in the Nvidia control panel made my game stable with no crashes till I turned it off after 5+ hours of play.
