VR - What difference does Monitor/Desktop resolution make to performance?

[Dangerzone]

Hi All,

I currently run a HP Reverb, but my monitor is 1080p, and windows is set to 1920x1080.

If I was to upgrade to a 4K monitor - does this have any impact on the GPU processing / performance?

I know that the VR Mirror is just a mirror - however there are effectively 3 screens that the GPU is rendering for. One being the desktop with the icons/program running on it at the time - and the other two being the VR left and right eye. 

I'm not sure whether upgrading to a 4K monitor will have much of an impact on performance while in DCS VR or not and was wondering if someone could please advise?

Cheers

DZ

If you're absolutely in the lower end of the spectrum and on the edge of playability, it might have some impact.

I tested this extensively and it didn't make a difference. No change in frametimes with a modest PC.

There was a thread some time ago from a guy who reduced the desktop resolution and gained some performance. You might want to check it out for some ideas.

Does the Reverb have a way to reduce the mirror resolution in your monitor while playing in VR? That way you could test it yourself before making the upgrade.

Sometimes it just takes one person to get you to think outside the box. Reducing the desktop resolution would work if I end up having any performance issues, so that takes my fear away now from getting a higher res monitor. 

HP don't have their own software. They use WMR, so I'm bound by that (at least until I upgrade. Still looking at my options. The Pimax looks promising, but the price tag is just out of reach for now)...

If you are running your G2 at a higher resolution than the monitor (99% of people would be doing this) then I think it would make no difference. Your monitor is only viewing a mirror of one or both of your VR screens with in VR mode.

It makes no difference whatsoever directly... If you are recording from your screen it will, thatsbit

I have three 1440 monitors. I have tried just using one 1440, using a single 1080 monitor, and minimizing the window of the 2d projection whilst in VR. None of these appear to make any noticable difference for me. The biggest issue is what other software you have running.
