I'm getting around 90 fps especially in the beginning. The image fidelity is so so with SteamSS 100%, and much better at 150% but the fps will drop which makes it go down to 45 fps (due to motion smoothing/reprojection). Interestingly, motion smoothing seems to turn off automatically whenever the framerate hits 90.

EDIT: Well, the Vive/SteamVR system works differently. I can disable motion smoothing in the option but no way to disable reprojection (at least in the current version, AFAIK) which will always kick in once fps is <90 and the effect on frame rate would be similar to having motion smoothing on.

EDIT2: Ok thanks to the gentleman that told me how to disable async reprojection I was able to do this (It's quite convoluted with Vive/SteamVR, you have to bring up DisplayVR View window, click on that and press SHIFT-a). In this mode, I'm seeing 75-90 fps with this test scenario and above settings (75 when flying low towards buildings). However, whenever the frame rate dips below 90 the stuttering/tearing occurs when moving my head around inside the cockpit which makes the game rather unplayable since it induces nausea and sense of disconnection from the world. I can now see why Steam doesn't want you to mess around with reprojection setting. This though might be good for Valve Index at 144 Hz with reprojection on since 72 fps will be utilized effectively.

Now the open Beta has been released to Stable I have done a comparison, I have not noticed any major differences, might be slightly faster. I am not sure the enhancement has been released to this version so if not disregard.


It does seem a bit smoother in general, but it is very slight, so could easily be placebo effect.

I´m one of those who see a major improvement (although there´s always room for more, its just a comparation as before). I have the Vive, sometimes i get 30 fps but it is a lot fluid. Most always in 45Fps. I know that without my system specs and testing its difficult to understand. I´m sorry i don´t have room available right now for installing stable version to test. 1080Ti Zotac, 32Gb Ram 1800Mhz, M.2 SSD, 2x SSD´s, 1 OS SSD, I7 4790K 4.4, Liquid Cooling, and HTC Vive. Tested in VR With this graphic settings on DCS Beta. SteamVR SS1.0, DCS VR Options SS1.5 and forced IPD 68 (DCS VR Options).

Cockpit Global Illumination: On
Message font scale: 1

EDIT: All of this using some mods and lots of objects in my missions. With vanilla i got 45 FPS in VR (just a note: 145-175 FPS in 2D).

A little late to the party, was waiting to upgrade the system so I could post both before/after numbers.

Code:
Settings universal to both systems

Textures: High
Terrain Textures: High
Civ Traffic: Off
Water: High
Visibility: High
Shadows: Low
Resolution: 3840x1600 (except VR)
Res of cockpit displays: 1024
DOF: Off
Lens Effects: Flare
MSAA: 2x
Motion Blur: Off
SSAO: off
Clutter: 100
Tree Visibility: 5000
Preload: 47800
Chimney: 1
Gamma: 2
Aniso: 8x
Terrain Shadows: Flat
Global Cockpit Illumination: On
VR Pixel Density: 1.0

*All tests run with reprojection turned off via: 
SteamVR Settings>Mirror Display>Click in Mirror Display window> Shift+A

Both systems use:
Samsung Odyssey+
Windows Mixed Reality (quality to set to Very High)
Steam VR 1.6.9 (1564184397)
Steam VR super sampling 210% (2064x2580 for each eye)
Old system
Code:
Intel I5-4670K @3.4ghz
16GB DDR3-2200
2080Ti Founders Edition at stock (factory OC)
Windows 10 Enterprise v1903
2.5.4.30386 - ran first 9 sec
Average framerate : 45.0 FPS
0.1% low framerate : 31.3 FPS

2.5.5.33552 - ran first 8 sec
Average framerate : 44.9 FPS
0.1% low framerate : 37.7 FPS

Included the 0.1% lows because that is the only metric that really changed - maybe significant?

New system
Code:
AMD Ryzen 3800x stock
32GB DDR4-3200
2080Ti Founders Edition at stock (factory OC)
Windows 10 Pro v1903
2.5.4.30386 - ran first 7 sec

0.1% low framerate : 21.6 FPS

2.5.5.33552 - ran first 10 sec
Average framerate : 59.9 FPS
0.1% low framerate : 12.1 FPS

Some are seeing significant improvement; others are seeing a reduction in VR performance. We are seeing the same results with clients over the past week or so. As you might imagine, we are trying to pin down this discrepancy. We are unclear if it is based on drivers, VR set, graphics settings, VR settings, missions, etc. As such, we are asking for your help!

Using the TF-51D Instant Action mission Flight Over Tbilisi, please provide your average FPS in VR for the first few seconds in the current Open Beta. Then, run the same test in the Stable version that does not include the optimization. This allows us to determine the delta. Please turn of ASW! Please include in your report:

- FPS for both tests
- System specs
- Graphics settings
- VR settings
- Type VR set used and driver version

Please, please, please keep posts to the data requested without off topic and commentary so that we can easily sort through and analyze the data. Posts that cannot follow this direction will be removed.

Note: if you are getting 45 FPS in both tests, then in all likelihood, you did not disable ASW correctly.

Thanks
Hi Wags, I apologize for the stupid question - but how do I get FPS to display in VR? I've been trying for a while and cannot see it displayed anywhere. If I unplug VR and run DCS off the normal laptop screen, I can get the FPS counter up in the corner like expected. But as soon as I go back to using VR, I'm not seeing the counter anywhere. Is it accessible somewhere else when running VR?
