OptiX rendering, to my knowledge, uses the RT cores in the Turing architecture cards like my 2060. How does tile size affect the render speed?
As far as I know the general rule is to increase tile size for GPU rendering and decrease for CPU rendering. I did not notice a significant difference in render times between 64x64 and 3840x2160. I'm sure there are a million things wrong with this testing, but I have no idea what they are. I don't think I know enough to test and pull off a rigorous test, so I was wondering if there is a benchmark my simple google search can't find or (if such a benchmark is unavailable) there are guidelines to test this myself on my own hardware.
Thanks for any help you can provide!
I did some quick testing and I'm beginning to think that larger tiles are faster, but I'm still not sure. I have no idea how to test things like this well and rigorously, so I think I'll just go with the rule of thumb bigger tile size is better... I'd still appreciate any advice on running tests myself or seeing someone else's tests.
