remove link to deprecated nvdiffrast version?

[s-laine]

Hi, developer of nvdiffrast here. It looks like the Deep3DFaceRecon_pytorch repo points to a really old version of nvdiffrast from March 2021. That link should probably be removed so that nobody installs that version by accident, e.g., via a recursive git clone.

Also, the current version of nvdiffrast includes a Cuda-based rasterizer that doesn't require OpenGL. You may want to consider switching to that by default, as setting up OpenGL can be tricky on some platforms.

Thanks for your suggestion, I have removed the submodule linked to the old nvdiffrast version. Everyone now can just follow the instruction to git clone the latest nvdiffrast for installation.

I read the latest documentation, I wanna know if we want to switch to Cuda-based rasterizer, do we just need to replace the context creator from RasterizeGLContext to RasterizeCudaContext?

Yes, that is all it takes.

I have updated the code and README for easy switch. Thanks for your suggestion.
