Questions about 2.0 release: request for lowered GPU requeriments for both 3 vendors, MacOS GPU support.. #160

Closed oscarbg closed 1 year ago

oscarbg commented 1 year ago

Hi,

first, thanks for a nice release..

still asking if GPU requirements can be lowered somehow..

I have and "old PC" with 3 GPUs from Intel AMD and Nvidia:

Intel Skylake i5 with HD 530(Gen9 iGPU) AMD RX Vega (gfx900) *Nvidia Maxwell (sm_52)

and seems neither is supported..

any specific reason to limit to Intel Xe+ (>=gen12), RDNA2+ (>=gfx1030) and Volta+ (>=sm_70)..

finally asking if there are plans for Apple GPU support (i.e. merging Apple MPS pull request (https://github.com/OpenImageDenoise/oidn/pull/138)) in next release (so 2.1? release)

thanks..

Hi,

Sorry, we cannot lower the GPU requirements but OIDN 2.0 can still run on the CPU on such machines with full functionality.

Apple GPU support is planned soon but not by merging #138 because it needs to be almost completely rewritten.

Hi. Not including nVidia Maxwell architecture is it because of some limitation?

nVidia OptiX works seamlessly on Maxwell cards.

Hi. OIDN is using NVIDIA CUTLASS, which dropped support for Maxwell and even Pascal. OptiX is a completely different product so it's not directly comparable.

OK, sad because I won't be able to use OIDN with acceleration on my GPU. But anyway, thanks for your excellent work.
