Cuda on in soft scrape its soft, with cuda off its more harder. But its weird I'm getting no better performance difference with the scrape brush but it behaves differently with cuda on and off. I didn't realise it didn't work with all the voxel brush's.
#3D COAT VOXEL SCULPTING GTX 1080 CODE#
I'm now convinced that if Andrew recompiled his CUDA code to be updated to CUDA 6.5 or newer, and expanded it to all the tools in the Sculpt room that it could be utilized on.3D Coat would be an absolute BEAST in terms of sculpting performance!Īndrew has focused only on Surface mode brushes for the past several years, and that is why there are many more surface mode brushes. Not the Move, Transform or Pose tool.although I have asked Andrew about using CUDA on these, because they need it as much, if not more than the Voxel brushes. Some of it depends on the alpha used, whether falloff and smoothing is applied, etc.The other thing I would add, though, is that CUDA overall, contributes very little to the sculpting experience because it is limited to Voxel brushes. It isn't consistent throughout all Voxel brushes, either. My CPU is a 6-core i7 970 OC'ed to 4Ghz, and 32GB of RAM.so it's not like the CPU is a slouch. I don't know if it's because the Pascal cards have such high clock speeds and memory speeds, but even with 3D Coat on CUDA 1, that was a major difference. I thought."is this really CUDA doing the work?" I then went to the GEOMETRY menu > turned CUDA off > tried again, and there was a night and day difference. However, I recently bought a GTX 1070, and was using the SCRAPE brush on a 35mill poly object, and noticed that it was insanely fast.
Granted, Andrew hasn't recompiled CUDA in 3D Coat, so it probably isn't going to work as optimal as it would if he recompiled it for CUDA 7 or so.
