Random "block artifacts"

[syberand]

So, I am rending some water using Phoenix and vray GPU and I am getting some random walking blocks over my surface. Totally random, some times a frame is fine and the next time it is there. I also have a similar problem with deform meshes.

Hi syberand,

Is it possible to forward the scene with all the cache files so we can investigate? Details regarding the system configuration and exact V-Ray/Phoenix/host app version will be greatly appreciated. You can send them through our contact form, just make sure to mention this thread in the email.

I seem to have fixed it. RTX seemed to be the problem with deforming meshes. When I switched it to CUDA it worked fine, though a bit slower.
