  4. Don't upgrade that NVidia card just yet...

    in CG & Hardware Discussion

    Posted

    I've been a loyal nVIDIA follower since day one, not anymore. I was having issues with display driver stops working in windows 7 with a GeForce GTX 460 (Fermi) card in a Core2 quad Q6600 machine. Out of disgust with nVIDIA for not addressing the issue I replaced the GTX 460 with a Radeon HD 7850. The HD 7850 works flawlessly and even smokes the the GeForce GTX 660 I have in my i7-3770k machine. I won't view AMD as inferior to nVIDIA anymore. Just my opinion, but I think (hope) OpenCL is the future.

    That happens because you cannot use the same card for viewport and CUDA. If the CUDA kernel runs too long the driver will time out. Infact the reason it times out the driver is because kernel is tooo long and should be split in to multiple parts.

    Using two cards you wouldn't get such problem OR edit the registry settings but that can have consequences.

    That shows you how unoptimized the 3DCoat CUDA kernel is.

    It wasn't with my GTX 470. I am thinking that the scaled back BUS size (from 320 to 256bit) is the culprit. Everything else is faster. That was a ridiculous move on NVdia's part. Nevertheless, AMD talks out of both sides of their mouths. They trumpet their streaming capability and yet consistently offer crappy driver support. It's like bragging about how big an engine you have in your car, while the transmission is broke down and no attempt is made to get it up and running.

    Again, it ain't about monopolies or using a standard everyone can utilize. It's about AMD not giving a flip whether or not your gaming card works with a professional CG app. They put all their development efforts toward making sure their drivers work well with Games and games alone. The whole bit about Adobe offering some support for OpenCL is not a show of commitment from AMD, but on Adobe's part to kick AMD in the rear, to make their shizzle work...likely do to all the Adobe consumer push for the support.

    It working with some of Adobe's apps doesn't mean OpenCL support in 3D Coat would work well with AMD cards. The way AMD looks at it, if you buy a gaming card from them, you get gaming support/drivers. If you buy a professional card from them, then you get professional/CG support.

    Where you getting this from? Have you written a line of code in your life? OpenCL is equally powerfull as CUDA. And it works on CPU,GPU,FPGA,ASIC hardware. Sadly CUDA only works on NVIDIA GPU.

    All Adobe software support OpenCL. It will continue to rise because it is an Open standard much like OpenGL. Everyone was talking down OpenGL when it was introduced. Now look where it is. Its used in every CG/CAD application on this planet.

    Infact the next start to rise is OpenRL. Anyway this whole crap with AMD having bad drivers is a total sham. I have a AMD 5570 and 3d coat works perfect with it. OpenGL & DirectX.
