This might be a bit general but…
I have been battling to get good enough performance under VR with my SDK2 Rift on my i7 4.2Ghz, dual (SLI) Nvidia 980 GPUs. Clearly there is optimization that can be done, but how on earth are Sony hoping to get good performance in VR from a console that cant even cope with full 1080 gaming most of the time (and certainly cant match the 4k output of my setup)?
I have read many threads here asking for ways to tweak UE4 performance under the rift and ways to try and hold 75FPS, clearly on a closed system like the PS4 then Sony can control some of these issues but I dont see why my machine (and so many others) are having poor performance. Shadows seem to kill performance but generally things just feel like VR requires too many compromises for anyone other than early adopters/devs at the moment?
Interested to see what others think Sony are planning or where / when we can expect more performance to come from (other than Nvidia finally getting SLI working with VR!).
Sorry if its too general;
