VR optimization?

I’m not getting the performance I would expect when playing in VR, are there any DCS specific settings or tweaks or a guide for improving performance?

I’m getting a fair bit of studdering and 1-2 second freezes when in VR.

I’m running a rift S at 1.3SS.

Messing with the trees and grass doesn’t seem to make any appreciable difference in performance, or really any other settings for that matter. Dialing the SS to 1.0 really doesn’t seem to make a difference either (except stuff is uglier of course)

System:

WIN 10

Ryzen7 3800X @4.5ghz

EVGA RTX 2070 XC, water cooled running 2150/7500 clock/ram

16GB DDR3200

1TB SSD.

Suggest you post this in the VR sub-forum, would probably get a lot more feedback there.

With the 2070

Only expect lite / med duty's in VR with DCS (DCS was not made for VR like the store games)

Pull back the pre load radius to 30 - 40 and vis range to medium, this lifted the GPU to 90% to 100% utilization for the quick test I did and held 45 fps with high graphic settings on the 1080ti

For a mission I possibly need to dial it back more, this is with a PD of 1.6 standard rift. In a small free flight mission.

Testing a few settings to get a smooth low city flight. It's about smoothing it out and having a nice steady smooth stream. Variation is what causes stuttering.

I.E hold 45 no matter what your doing or where your flying etc. Negatives in the headroom here and a few little dips to 38 fps as see in the video.

Quick video low flying at the Gulf, showing oculus diagnostics, Open Hardware Monitor and Msi.

This is still not a mission with lots of Ai, this was just to fine the settings to be sort of smooth here in a large city with max eye-candy, it would be close tho for a medium size mission at a "steady" 45 fps. Once away from the city possibly.

Tun on (Visible HUD) = Performance. To see this when playing.

1080ti has around 20%...ish on the 2070 depending on game.

Thanks for the input Dave, ill check it out.

Indeed, go with medium visibility range. The visibility range (distance buildings render at) is by far the biggest CPU hog in the game. In VR, CPU is generally the bottleneck unless going nuts with the super sampling.

WEll I went ahead and upgreaded to a 2080TI and water cooled it, runs much smoother now.. if only by brute force.
