I haven't done many furballing because I mainly fly the hog and am practicing A2G things in our training pipeline.

Yep, I find VR is much more acceptable in A2G missions, as motion reprojection artefacts of nearby aircraft are less commonplace.

 Varjo's new Motion Smoothing is a total wreck and pathetic , worse than any I have ever seen... That thing should have never been released in the state it currently is in. 

Is it that bad? 😬 


Away, so I havent tested it yet.

can it be used with ”Force_steamVR” or do it only work in Varjos default? 

I actually do not really need it after my upgrade, but was still hoping. That VR Sim guy vid was promising.

I get 90fps in most situations now, but for the few exceptions it wouldnt hurt.

As a side note, I noticed that there is teo cores sharing the high thread since some time back, and not only one. 
I get 4-6ms frame time with my 13900KF and the 4090 is at 8-11 so always GPU bond.

Yeah it is really that bad. Can't really say on your force steam vr question.

At the current state, Varjo's motion smoothing works as long as your head remains stationary.  If you move your head around there's this 0.5-1sec period of image retention artifacts, then everything catches up and it becomes smooth again.  The cost is also high on GPU/CPU processing, so they need to work on optimization.  I think they're trying to implement it such that it will work with both SteamVR and OpenXR, but the problem is that it doesn't work well with either.  Might be better just to stick with SteamVR's motion smoothing...but to actually make something happen is probably harder than you think and that's why it hasn't happened yet.

The good news is that this latest release is the only version that Varjo desktop shows no artifacts on windows taskbar with head movement on my setup (since the 4090 upgrade).

@Readyhow did you do 

  1. OBS: No render lag and no encoder lag.

Couldn't figure it out

There is an option to display a status window. In there it gives this information.

Hi iirc i have peformance mode and ProBalance service enabled. Will check when I return home from travel. 
Edit: yes I have them both turned on.

Yes same here. I couldn't really tell the difference. I guess these stats are still from your fpsVR period? I did not start using csv exports via OXR yet, did you?

these are from OXR which seems to work very well and provides data in a nice CSV file, i'm trying to get to a more consolidated pov before i go live with some of the numbers, nothing traumatic i just enjoy playing the game more than i do perf testing it , I also moved over to Syria and the Apache for my testing as it was too easy to max the fps with the 4090FE

Ahh nice. The hog remains my airframe of choice for the foreseable future.

Will jump back into using csv's and update my benchmark table when I return. I am tinkering with anti-aliasing at the moment trying to get the best clarity, hoping I can stay off reprojection. The bottleneck is the CPU at the moment.

Slightly off topic, but why on earth are people with 4090s getting such low min fps on heaven?  I get 51fps minimum with my 3080ti, granted my average is only about 285 and high about 590.

For sharpening I would recommend using CAS from the openxr toolkit, it doesn't upscale at all but the sharpening is really nice; not sure how it might compare to 3Dmigoto performance wise though.

Because there’s more to it than just throwing the biggest GPU in a system.

The best I've been able to do with the 4090 and reverb G2 is to put steam scale resolution to 150% (sorry but i tested oxr several times and I have not noticed performance increase) and enjoy clarity. Of course motion reprojection and with 45 FPS. The 4090 is perfectly capable of manage this upscale not being upset.

  • 120% render resolution in OXR Tools
  • FSR at 75% (I have sharpening on but can't really tell a difference)
  • FFV on Quality/Wide
  • Reprojection on and set to Auto

How to set the render resolution in OXR? Would it be SteamVR instead?

What is FFV?

And where can I set reprojection on? I guess it is VR headset specific.

Nevermind, got them figured out. Thank you.

I find this video and related ones, very inspirational. Even though the creator is not running 2.8

Open-XR Toolkit tweaks;

  • FPS Lock - As per advice of @edmuss I locked the FPS in OpenXR to 55. This gives a lot of stability when looking at the in-game status bars. The green and white lines calm down. I do get a little bit of ghosting, but I already got used to that.
  • Reprojection auto - I am still trying to figure out having reprojection on auto and to have it kick in when it needs to kick in. With reprojection on auto it is not yet clear for me when the actual reprojection kicks in. 

OBS Performance impact

Since I always have OBS (recording) on when flying, the performance of OBS might also be a factor. When I was using a 3080 I clearly had an FPS impact when turning OBS ON/OFF. 

I changed my OBS recording to AV1 encoding and am tweaking my encoding settings at the moment, trying to see if I can get 4k recording going on without buffer issues or frame loss issues. Changing the encoder seems to have lowered my CPU usage a bit. Not yet clear if this a factor for DCS with my 4090. Will test a bit more and get some numbers in here soon. Will also add my OBS settings to this thread.

Reprojection on auto in DCS means that it's disabled, the auto setting is PURELY for MSFS, anything else it's turned off.  To get it do what you want, set it to always on and leave the reprojection rate unlocked within openxr toolkit.  The nomeculature is a little confusing but that's what you need to do 🙂

Obviously locking framerate with reprojection enabled is a no go, with the 4090 you should be able to hold >55fps till the cows come home.

Okay got it. I thought it could be off abd only kick in when needed. 

Will make a small video showing the stability with framerate lock adjustments. Am not ble to keep FPS above 55 because of CPU. Will make a recording to demonstrate.

Short question, have you tried SteamVR instead of OpenXR lately? When I checked, I got better performance with 4090 on steamVR, it received some stability and performance improvements no so long ago.
