I just tried exploring the Optical Flow TOP. It is giving me an error “The GPU or driver is reporting that Optical Flow is not supported. The GPU or the installed drivers may be too old.”
I am on Windows10 with an RTX6000 running “Production Branch” Version 552.86
I have just noticed that right clicking the desktop to bring up Nvidia Control Panel isn’t working right, so perhaps it is related to that.
I’m not too sure what is going on. Your video card and driver version should support optical flow, however, as the message states, that error indicates the driver is telling TouchDesigner that it is not supported.
It is suspicious that your control panel isn’t working, so it’s possible the driver didn’t install correctly. Maybe try re-installing the driver or possibly going back to an older version of the driver and see if that makes a difference.
Just to confirm, your card is the older RTX6000 around 2018? Nvidia has a number of very similarly named cards, so it gets confusing sometimes knowing which versions people are using.
Yeah, It’s the “NVIDIA Quadro RTX 6000” with 24GB GPU Memory
not the “NVIDIA RTX 6000 Ada Generation” with 48GB
I uninstalled the drivers and reinstalled. Didn’t seem to make a difference. Interestingly the right click still fails to launch control panel. I can run it directly from C:\Program Files\WindowsApps\NVIDIACorp.NVIDIAControlPanel_8.1.966.0_x64__56jybvy8sckqj\nvcplui.exe
So perhaps there’s a rogue registry entry or something. I’m not using optical flow on anything currently so it doesn’t really impact me at the moment. When the opportunity arises I’ll try it on a different machine and ping back if I can replicate it there.
