I’ve started not long ago developping in UE4 with VR in mind. I know keeping a constant 90 fps for the Vive is key. My PC is currently equiped with a Nvidia GTX 980Ti vc but I want to test what the performances would be on a lower end vc like a GTX 970. Should I down clock my GTX 980ti to get lower performances or is there an easyer way to do this? English is not my native language and I wanted to know, is there a term for the process of testing performances of differents computer set-up?
Thanks a lot for your help!
