OpenVR and TouchDesigner are using different GPUs

General TouchDesigner Discussion

I’m trying to use the OpenVR CHOP to get the position of a single Vive tracker inside TD. Whenever I add the CHOP though, it has a warning “OpenVR and TouchDesigner are using different GPUs” and it doesn’t output my tracker’s position.

What could be causing this issue? I only have 1 GPU on my PC so not sure how they could be using different ones.

I am running SteamVR without an HMD to just use the tracker with two base stations, which does work when I use an external Python library (triad_openvr) but not TD. Not sure if this could be causing this kind of issue.

+1, I have the exact same issue, no headset.

Sorry for the delay on this one. It’s taken a bit to get into the office and setup the basestations etc.

So far I’m unable to reproduce this issue. I’m able to drop down just an OpenVR CHOP with only one tracker connected and it works fine.
How are you configuring SteamVR so you can run without the HMD? Which settings are you assigning and what values?

I followed the instructions at the start of this one:
