Oh that sort of speedup would be very good, let me play around with reset rates. Currently I'm using 50% CPU on the desktop and about 60% on the laptop when rendering, definitely room for improvement. I will also compare with desktop-only (nvenc), but if I can double the current speed I get I'd be more than happy.
Thank you very much!
