In the switch to Video AI (from ‘Video Enhance AI’) it seems like the CPU and GPU utilization on the M1 Ultra has dropped a bunch. Previously it seems it was using over 10 cores (>1000% utilization) and most of the GPU, with 3.0 it was ~150% CPU and ~30% GPU, and now with 3.0.1 it is at ~350%(ffmpeg) and 130% (Topaz AI Video) with GPU used ~60%. Any idea if it will get optimized further to fully utilize the Ultra? I’m guessing it is tuned for the M1 Pro or M1 Max at this point.
Running a DV 2X upscale goes at 5.5 fps at the moment and I would love to see 2x or 3x that.
Hi - from my experience it’s not apparent that TVAI v3 is tuned for the M1 Max. However, you can get major performance gains by processing several videos in parallel - faster than real-time - when upscaling SD (480 or 576) to 1080 using Artemis or Proteus. I only have the base Mac Studio (M1 Max) but as you have the M1 Ultra you could achieve much more!
Thanks, Thomas - most impressive performance. I only recently found out from Topaz Support that 4 processes is a hard-coded maximum (per app instance) despite the settings offering up to 6 in Max Processes. On my Mac Studio (M1 Max base model), the optimum happens to be 6 (via 2 app instances).
I have definitely seen performance gains on V3.0.1 on my Mac Mini M1 machines. After about 3 parallels processes, then it starts to become less efficient.
One process would be .10 spf
Two processes would be .15 spf
Three processes would be .20 spf
