That sounds feasible Ped7g... I've been framerate focussed for years so that makes sense. It seems incredibly smooth going on a straight.
I seem to have a solid 90 with plenty of headroom. Had the PPD on 1.5 and it looked good. Boosted it up to 2.0 and it still sings. Still showing a little headroom remaining as well. Never set it at 2.0 for anything b4.
The ppd has left me a little confused though. Having a cv1 the resolution for both eyes together is 2160*1200 which I thought (may be wrong) would super sample at 2.0 leading to a res of 4320*2400, around 4k thats then downscaled for maximum niceness.
In the LFS view menu it tells you the render target size and when I use 2.0 in the oculus tray tool LFS reports a render target of 5344*3184. Just an insignificant 7 million pixel difference. Maybe I've misunderstood something about supersampling.
It still mindblowingly runs smooth but I don't understand the numbers. A ppd of 1.5 put me nearer to 4k but that should be lower too. Dunno if I'm missing some other game internal setting but I've seen nothing that should affect ppd in there.
