Advanced Member insignet Posted July 17, 2017 Advanced Member Report Share Posted July 17, 2017 Which Graphics cards are the best for use with 3DC? Nvidia GTX 1080 or Radeon™ Pro WX 7100? I'm using 3DC for high poly and low poly work. Any thoughts? Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 17, 2017 Report Share Posted July 17, 2017 Your OS base system is windows ? GTX 1080 ti is best suited for that task. Quote Link to comment Share on other sites More sharing options...
Member andre3000 Posted September 7, 2017 Member Report Share Posted September 7, 2017 Is sculpting and SSAO accelerated on Radeon? I read CUDA and think Nvidia only. Quote Link to comment Share on other sites More sharing options...

I read CUDA and think Nvidia only. Several years ago, CUDA made more of a difference than it does now, as it accelerates only the Voxel brushes. But the brushes are otherwise heavily CPU multi-threaded. Plus, CUDA implementation in 3D Coat hasn't been recompiled/updated, which would allow it to take advantage of some of the newer CUDA technologies. The main reason for that is Andrew doesn't think the benefit of doing so would be worth the cost in time spent in development. Surface mode sculpting is where 3D Coat really shines. Voxels are still really good for carefree and fast boolean operations. So, in short, CUDA really doesn't have much of an impact on performance in 3D Coat. A good CPU, with lots of cores/threads and fast RAM is where you want to invest your hardware $$$, if you want to get the most out of 3D Coat. 1 Quote Link to comment Share on other sites More sharing options...

When I ran CPU tests on the same gtx 970 which indicates that it does use the gpu exclusively. Quote Link to comment Share on other sites More sharing options...
Contributor ajz3d Posted September 7, 2017 Contributor Report Share Posted September 7, 2017 3D Coat doesn't use AO. At least not to my knowledge. Quote Link to comment Share on other sites More sharing options...

Contributor ajz3d Posted September 7, 2017 Contributor Report Share Posted September 7, 2017 IIRC AO calculations utilize CUDA. Quote Link to comment Share on other sites More sharing options...

Using Voxel brushes, you might notice a bit of difference, but probably very little. 1 Quote Link to comment Share on other sites More sharing options...
