Reputable Contributor AbnRanger Posted June 7, 2013 Author Reputable Contributor Report Share Posted June 7, 2013 I actually discovered recently, that the large brush lag (on 4k+ maps) in the Paint Room.....vanished (for the most part)....when I used an Intel i7 instead of an AMD Phenom X6. It was indeed a limitation of the CPU. Mostly AMD's. Back around Siggraph 2010, I recall some talk about Andrew using some Intel libraries. I guess AMD CPU's don't have access to those or Intel has some wicked prefetch voodoo going on with their CPU's. On paper, the AMD CPU I was using, was neck and neck with this i7 950, in most benchmarks, including Cinebench and others. And the 670 has a higher framerate overall, but is really, really crappy with wireframe, and I suspect with CUDA. When I threw my old GTX 275 in, it seems to perform smoother, when sculpting with Voxels. I think some of your issues with sculpting could be a little bit on the hardware side, too.

Contributor BeatKitano Posted June 7, 2013 Contributor Report Share Posted June 7, 2013 You cpu thing is why I never go with amd on cpu (nor cards mind you but for other reasons ) . They can claim performance over intel hardware, intel has always put some optimized libs out there, and it's always integrated in cpu intensive apps... I remember the SSE II/III days, when you didn't want to use amd for that reason alone, the perf boost was pretty dope... Quote Link to comment Share on other sites More sharing options...
Advanced Member geo_n Posted June 7, 2013 Advanced Member Report Share Posted June 7, 2013 Ah now we're talking ! Proprietary gpu/cpu acceleration is the way to go if you absolutely want to benefit from those component. I completely agree with this. If Andrew would do it himself I think thats a good effort rather than relying on third party. Quote Link to comment Share on other sites More sharing options...
Reputable Contributor AbnRanger Posted June 8, 2013 Author Reputable Contributor Report Share Posted June 8, 2013 I would be happy if the brushing and large edit operations in the Voxel Room (Move, Transform, Primitives w/ Models pallet, and Pose Tool), all were OpenGL and/or DX accelerated, instead. Somehow, Mudbox is doing it and I don't know if they have moved to DX 10 o 11, or still on 9. I think a move to DX11 or OpenGL 3-4 overall would be good move. Both have been out for 3-4yrs now, and all newer games are written for them. DX9 is about 10yrs old now. Quote Link to comment Share on other sites More sharing options...
