Cycles Raytrace mode uses 100% GPU for everything it does, so of course it’s going to max out most of the time. (Turntable is not designed to work with Cycle’s Raytrace mode.) Raytrace is using the GPU 100% even though the display may still seem slow. | Cycles Raytrace mode uses 100% GPU for everything it does, so of course it’s going to max out most of the time.

Rhino has tried to improve this over the years by packing as much as possible on the GPU, but there’s still the problem with the CPU just iterating over large datasets in general. | Rhino has tried to improve this over the years by packing as much as possible on the GPU, but there’s still the problem with the CPU just iterating over large datasets in general. | ||

It takes my pit crew 8 minutes to get everything ready.

If you really want Rhino to be faster, you will need to first invest in a faster CPU… Then augment that with a better GPU. | If you really want Rhino to be faster, you will need to first invest in a faster CPU… Then augment that with a better GPU. |
