The gui did tell me that a ‘Reduce Jittery Motion’ pass would take significantly longer. Well I have a RTX 3090 in here, so I thought, what’s the worst it can do right?
14 Seconds per Frame, and Performance Monitor shows no usage on the CUDA charts. CPU shows 90-95%.
I am upscaling 6K to 8K prores to prores. I will check on the SAM/ReBar.
Is there any switch of some kind to select GPU vs no? I don’t recall such a thing… what would be the reasons the program would decide not to use the GPU?
File → Preferences. It should be the first option you see. It might be set to auto. Change it to your 3090.
Umm 6k to 8k might be the real reason. That’s a lot of heavy reading and writing. Your CPU’s going to have to work much harder to keep the GPU loaded. Again, SAM/ReBar should help there. Gen 5 PCIe might also help in that situation—provided your SSD isn’t like my cheap one that actually writes slower than 2.4GHz WiFi once the tiny cache gets filled.
I don’t mind if it’s slow, if it’s using all the power I’ve got. But it’s not using the GPU, clearly. AI Processing (the option in File ->: Preferences) is set specifically to the 3090. It is only set to 2 processes though… what selection should I make here?
ReBAR is currently turned off. I’ll need to reboot and find a wired keyboard to fix that heh.
Someone else recently mentioned setting power management mode in the nvidia control panel to prefer maximum performance. I tried that on my 3080ti and it does seem to increase the utilization form 30% to about 90, but I have not tested specifically if it actually processes things faster.
A side effect of that setting is that Desktop Window Manager now uses 100% of the GPU when idle. So it makes it a little harder to read the graphs.
