Use GPU for otherwise very slow "Image Film Grain" node (if available)
The "Image Film Grain" node was effectively generating large noised images one pixel at a time looping through randint() calls, which is a very slow process. This forked version uses pytorch and is much faster - on a 5950x + 4090 system, 1024x1024 images went from taking at least 30 seconds to maybe 0.2 seconds. The benefits are even greater with larger images, which drop from taking several minutes to under a second.
Oh hey thanks. Yeah a lot of the noise/image stuff could be moved to torch. Will most. Some stuff I found PyTorch implementations of kinda inferior. Like doing sharpening.
Did you mean to include a "CLIPSeg2" in here?
