Please add support for GPU transcode on AMDATI GPUs

Post » Sat May 12, 2012 7:37 am

Currently NVIDIA GPUs can benefit from reduced texture streaming lag by enabling GPU transcoding to convert the compressed textures on their GPUs rather than the CPU.

Unfortunately the current implementation only supports CUDA. CUDA is a proprietary technology from NVIDIA that prevent users of AMD/ATI GPUs receiving the benefit of GPU transcoding.

Thus I am requesting that OpenCL support for GPU transcoding be added so that users of AMD/ATI (and NVIDIA) can benefit from GPU transcoding on a non-proprietary technology.

Unfortunately, enabling this option on my computer made negligible difference in the horrid texture streaming.

What NVIDIA card and CPU do you have? I read from a comment by an NVIDIA driver developer that it will only enable on high end CUDA GPUs (460 or better).

He also said it has a bigger impact on those people with a slower CPU, thus if you are using a Intel i7 CUDA may not be any faster than the CPU.

I only have an AMD Phenom II thus my CPU would be slower than my GPU (a 6950).

so ATI has not transcode options

From what I've read it appears that the OpenCL method is not as efficient at the compression and actually does not even improve performance.
Isnt that why beth posted +vt_maxPPF 16 as a method to get the cpu to tackle more of the work?
