Overall performance depends on how many threads are being executed, and how much the work can be done by the GPU vs. If I run only one of them, it runs at around 5 to 6 fps, not 11 to 12. As I type this I have four 480->4K jobs running. Performance is not just about the video card either. On a 4090 w/24GB of VRAM you may get 8 sessions running, but you still won’t get the utilization up over 30 or 40% - but your VRAM will be almost 100% allocated. However, when I run upscale jobs I max out the VRAM after 4 simultaneous sessions, while still only putting a 30% overall load on the card. The 3080Ti I can run a dozen simple FFMPEG compression tasks and still have processor and memory to spare. I have a EVGA 3080Ti Hybrid w/12GB of RAM, and my most common use case at the moment is upscale of 480圆40 DVD originals to 4K. ![]() In general, LONG before Topaz maxes out the process nodes of the graphics card, you will runout of VRAM. The Windows Task Manager, and most monitoring utilities, calculate load on the entire card while Topaz really only exercises the Tensor cores, encoder/decoder and VRAM. ![]() IMHO, the ONLY way to judge TVAI utilization of your GPU is to use something like GPU-Z.
