I have rather high end PC and upscaling videos are slow. Current system usage seems low. Would it be possible to speed up the upscaling for higher end setups? I remember other setups to take less time and use more system resources

Video is ~3 minutes long.

Setup:
R7 5800X3D
32GB RAM
RTX 4090
Samsung Pro NVME SSD
