Several things:
- VR runs fine with mobile GPUs now - on NVidia side. I’ve successfully ran ROBLOX on Rift & 750M, and we have several people using 980M with Rift and Vive. 750M would require bringing the quality level down - can’t run on quality level 10 at 90 FPS in VR… - but 980M would probably run on high quality levels.
- There may be compat issues between Oculus and AMD cards. I know we had a laptop with AMD mobile GPU that Oculus refused to install on. This was before retail - not sure what’s the AMD situation now.
- All Oculus demos - if we’re talking about their, uh, Dreamdeck I think it’s called - are pushing GPU to its limits. They seem to be designed to barely hit 90 FPS on GTX 970
- Rift right now will provide better experience on worse hardware due to asynchronous timewarp. I’m really hoping Valve comes to their senses and implements that for Vive, it’s a game changer for low-end hardware.
