Hey Guys,

I been doing some testing last week or so and came to some good conclusions.. My Specs are in the sig but that is really not all important for setting an optimal experience as everybodys rig specs and hardware will be different..
I have a Odyssey+ VR Headset and been flying DCS in VR for almost a year.. I also used a program called fpsVR but it is not needed for DCS but a good FPS and Frametime counter able to display in VR Headsets..

What I found out the Frametimes are very important in maintaining a smooth experience and basically you would want o keep the FrameTimes under 20ms for a WMR Headset.. WMR uses SteamVR and Steam Mixed Reality programs to work with DCS..

Now it would probally be best tested on a Multiplayer server or mission with alot of objects but not overkill. I just used Beachead Interdiction for the AJS 37.. I may end up tweaking a bit more but the few MP servers I went on the results where very good..

here is a readout from fpsVR to give you an idea:





Now I guess you could end up with different settings in DCS according to your specs and SS settings.. so I am not going to post them up.. the thing to keep in mind is I have Motion Reprojection on Auto and use 150%SS in SteamVR.. you must keep your GPU FrameTimes under 20ms. the optimal Frametime is 11ms but nearly impossible in DCS could depend on the mission as well..

So basically I used Beachead interdiction AJS37 and set from there.. it had a few objects and 3 planes flying and low level.. I figured a good base mission to try it with.. I did keep the PD in DCS @1.0 as I used SteamVR SS 150%..

just remeber no matter the setting just keep your GPU FrameTimes under 20ms the closer to 11ms the better.. if you run fpsVR you will see the 99.9Percentile but that was a blip like when I enabled the EP-13 Maverick display and such.. when using fpsVR you get the readouts live so it is easier to make sure you maintaiin under 20ms that is the key.

I guess the best hope we have for VR in DCS is Vulkan.. I hope this helps you guys that use VR a bit..



OK I have done some more testing and added my Specs in the sig that where removed for some wierd reason?? Anyhow I OC my CPU to 5.00GHZ Up from 4.8 it was at before on the last test.. In DCS A high OC helps really well.

I also tried setting my MSCONFIG too a very bare minimum of Microsft services to run, I am still trying to figure if this helps any but initial testing says it did not.. Altho my CPU Utilization was lower and RAM usage was down a bit along with less processes running.. I will have to test this again with the new clock speed..

This run I plan on setting a log again for the Beachead Interdiction mission to see if there was a improvemnt or not.. Once I run that test I can compare with this run to see if any difference.. So barring that test I will report back in about hour..


here are the results:

Thank you for your time and effort in making these reports.
I haven't made the leap to VR yet, but am keenly interested in all and any information.
By chance have tried various headsets (brands) to make comparisons??

No I would like to try the I think it was the Reverb 2160x2160 and the Pimax 8k but I will just stick with the Odyssey plus for now.. I do hear good things about both, I have read about Samsung put in a patent for a 180degree OLED Screen for VR that would be pretty cool if they get as higher resolution for it..

I did try to set the Resolution closer to the native of Odyssey Headset and found I do like it with these lower native resolutions for the SuperSampling to be higher I currently have it set Global @150%. I think that is the limit for DCS in Elite Dangerous I can probally go higher..

I am sure the VR Manufacturers will come out with ever increased resolutions but I am almost afraid of what kind of Graphics card would be needed to push it.. Especially in DCS but I hear they are looking into Vulkan API for DCS Which should help.. I also hear the DX12 runs a bit smoother then DX11 Games in VR..

So it really depends on what you like and how it looks to you.. I mean I would love to crank all my settings too max in DCS but with my 1080GTX it is not gonna happen.. I could probally tweak it a bit more by lowering the SS and going with higher Graphics setting but then it looks to fuzzy and a soft image.. with it at 150% SS it looks pretty good too me.. YMMV

Your Welcome I am just hoping someone gets some usefull info here.. Oh and with the Motion Reprojection it keep the FPS mostly @ 45 but it does this by skipping a frame or something to that affect.. it is not a perfect solution but far better then running it without motion reprojection.. Sometimes in a busy environment like if you are low on the ground and banking and looking out the pit towrads the ground and there are buildings there they seem to have a double image..

Most times I am too busy doing the Avionics to see it but if you look you can see it.. I dont find that too bad but I have read some users don;t like it at all.. Overall VR is really cool I have my 3D and the VR Really adds to the immersion even with the limited FOV, it is sort of like looking out through a Scuba mask but Pimax is changing that with the 180FOV..


I am just gonna save my pennies for the next big thing

There are interesting solutions that can reduce the need for a huge graphics card 'oomph', eg. eye tracking that would cause the image to have maximum resolution where you're looking, rather than the entire picture. You still need an expensive, high-res panel but you don't have to render everything high-res, which as far as human eyes are concerned is just fine.

This is out of reach for most of the gaming public right now but it's the future.

Well it is “cheaper” than XTAL VR.

Prices will come down. Resolutions and performance will go up. It’s like when HDTVs first arrived in the 2000s. I remember 720p HD sets costing over $1k... for like a 32 inch. Nowadays, Costco has 50+ inch 4K sets for $400-500.

Well with the new OB 2.5.6 patch this is all blown to hell and my FPS have tanked as has frametimes on the GPU.. CPU Frametimes seem to have improved but my GPU is really struggling now.. How about you?
