now that AMD can use CUDA the future is limitless
https://github.com/AdaptiveCpp/AdaptiveCpp
and yes it does work currently have an intel arc and a separate AMD GPU setup and both PCs are able to use DLSS with the CUDA library on games like Cyberpunk
the results are fanfuckingtastic talking Nvidia fog and shadows from CUDA on any GPU
Curious how well this works with some open source projects that have separate implementationa for Nvidia and AMD/Intel GPUs.
Although it sounds like the devs would have to be aware of AdaptiveCpp.
PortProton handles it just fine
https://linux-gaming.ru/t/ustanovka-portproton-ispolzovanie-wine-proton-bez-steam/24
even has the setting for it to make use of it
the GPU packages that are dependencies for AdaptiveCPP is as follows:
hip-runtime-amd
rocm-llvm
nvidia-utils
cuda
open source nouveau will not work for it
