HTC Vive crash on switch to HMD 'R6025 - pure virtual function call'


I’m trying out High Fidelity for the first time.
I have windows7, intel core 17-4790 - amd radeon r9
Open Steamvr, open interface.exe. The desktop version runs, but when I switch to Vive HMD I get the following error:

R6025 - pure virtual function call

And the program crashes shortly after.

Any ideas?


Are the graphics drivers up to date ?
I did some google on it, this can be a bug. I pass this one to @Jess


Yes it’s updated regularly and used specifically for VR.


Try the new just release Beta 20. Mabye that fix your problem.
