Optical flow issues

i’m attempting to use an optical flow TOP, which worked perfectly well in previous versions of touch (i last tested it in my 2022.29530 install) and it’s broken in the latest, giving me a “your gpu is telling td it doesn’t support optical flow” error. I’m using an RTX 2070 and i’ve installed the latest studio driver, restarted several times, un- and reinstalled touch, and even gone through the system requirements for the optical flow sdk and installed them all, still no dice. again, i would just assume this was an issue with my gpu but this literally works fine in an older build (which has other issues stopping me from using it anyway)

(this is in Beginners because i might just be stupid)

Unfortunately we moved to using the Vulkan version of Optical Flow in the 2023.10000 builds. Nvidia didn’t add support for Optical Flow in Vulkan on the 2000 series of GPUs. It’ll work on the 3000+ GPUs though.

guess i’ll start saving
