Blender CUDA on AMD GPUs [ZLUDA by Vosen]
In this video you will see how to use CUDA cores for your AMD GPU (Graphics Cards Units) in Blender 4.0 by using Cycles render engine with CUDA technology developed by Vosen.
You can easily test and apply to different software like Blender ZLUDA Core that is CUDA core for AMD Graphics Cards:
https://github.com/vosen/ZLUDA
You just need CMD and digit your commands:
you need to unzip the zluda's folder in a renamed folder (zluda)
you need to run zluda from your directory with cd (windows only)
you need to digit zluda plus exe and then the directory with software extension generally with exe single file
change Cycles render engine from CPU to GPU
apply and select CUDA instead of HIP
render and see the result
As you can see ZLUDA increase performance in particular for AMD Graphics Cards compare to HIP with little improvements
