Issues with current set up and Vive

I'll keep it nice and short. I found that I am unable to run my Vive with Steam supersampling at 1.5 without losing/missing frames with my current set up. I feel like with what I have I should be able to run 1.5 no problem.

I'm running:
MSI 1080 Gaming X
i5-3570k overclocked to 4.4MHz
8GB RAM

Now I know my CPU is a lot older than the GPU but it's overclocked to a half decent speed. Is it possible that this is the reason why it isn't running as smooth as it can be? Is there a difference when it comes to the 3xxx series of CPUs to the current 6xxx series, even if speeds are similar?

Supersampling shouldnt hit the CPU, however it will hit the GPU.

With a 1.5 sample on the vive you are asking for a resolution of 3240X1800 rather than 2160x1200.

The difference in pixels is 2,592k vs 5,832k. 2.25X the pixels... at 90Hz.

Come on man, be realistic here, the 1080 rocks, but not that much!

A single 1080 cant push a 4K screen at this rate, and you want even more from it.

Keep OpenHardwareMonitor or something similar open on your PC monitor while you play VR games with the supersampling on. When it starts juddering, take off the headset and see if your CPU is at 100% usage. If it is, then it's bottlenecking your VR performance, and if it's not 100% (or close to it) you might have another issue and we can go from there.

You don't multiply both values for a supersample. 1.5x means literally 1.5 times the screen size. You multiplied both numbers by 1.5, which isn't 1.5x, it's 2.25x, hence your end result of 2.25x the pixels.

The actual values would be 2,592k pixels vs. 3,888k pixels.

Fair enough, never played with DSR on in VR yet. The point still stands that VR is demanding and he is making it extra demanding.

Which games exactly are you playing with these problems blizzars?
