CPU and VR

[Hood]

All,

I currently have a 4770k (at 4.3) with Z87 Sabertooth mobo and RAM (not sure of speed). I use an EVGA FTW 1080.

My main game is IL2 in the Rift with all graphics settings maxxed but fps drops below 45. I could drop the graphics but would rather not.

I'm mulling over switching to an 8700k oc with the assorted gains from a new mobo and faster RAM etc. I will go to a 2080 when they're out.

Will there be a tangible benefit with a CPU etc upgrade?

Cheers

What’s the best way to check CPU/GPU performance whilst in VR?

MSI Afterburner reports the CPU use at 60, though the cores show between 58 and 80. GPU spikes at 98/99.

I don't understand the interplay between the CPU/GPU and the Rift. I get that a better GPU always helps because it is rendering 2 screens etc, but would a better CPU (and improvement from bus speeds, faster RAM and soon) help with everything else and ultimately up the fps? Would it take some load from the GPU?

Ok so GPU spiking at 99 might mean a very short term frame drop, but CPU at 50+ all the time might mean it isn’t shoving data to the GPU quick enough for the GPU to render at a high FPS? So the GPU is rendering half the frames that it could?

Or something like that...?

Reporting back. In IL2 with the same settings as before I got a circa 25fps increase.

Worth it to me.

So you got a nice increase going from 4770k to 8700k then?

Yes. And I’m now ready for the 2080 or whatever it will be called when it is released.
