And the next and final step for Totan will be a VR room. Some early screenshots, I started with the cabinet. This VR room I am going to make by so-called kit-bashing; this means gathering stuff other people made and putting them together and hope that that works. For the cabinet I borrowed some primitives from the VR room 3rdaxis made. I adapted them for the Totan cabinet:
The texture for the cabinet looks like this:
I am trying to keep the polycount low, VR is stressing enough as it is on a PC. The cabinet and backbox are 2k triangles, the metals (rails, legs, door, etc) are 22k triangles. Totan itself pushes 130k triangles, I guess the VR room will easily double that amount. The TAF VR room has about 2M triangles, I think I can stay way below that.
Very cool! Glad you got into VR. 
Regarding performance there are still optimisations that can be done in OpenGL by reducing the amount of draw calls per frame which can make a big difference, I'm not experienced enough myself to do the coding required for that but I know Caligula has it on his roadmap when he gets time.
