According me they take wrong way for WMR in P3Dv5. 

Update Sync:

Pre Render Sync:

Pre Render here is the Holy Grail (and for example DCS use this). Why we have here Update option only for WMR in P3D I dont know. Pre render option doesnt work with WMR as it should with P3D, too many jittery but with very good FPS and frame time.

 

Second thing I started to investigate some of strange behavior in some of planes in v5 (it doesnt present in v4.5). It looks like a large momentary lag when you panning your head in Virtual Cockpit. Just for very short time but its very noticeable. Most of all, I noticed it in the older models that the developer ported to P3Dv5. Next I noticed that its connected with gauges (maybe old version or so) - but it wasnt present also in v4.5, after some time, when you see this big lag several times for no reason, you just don't want to fly. I found some articles about refresh rate of gauges (maybe it could be a problem if you HMD and sim works for example on 45 or 90 Hz but the gauge works with 18Hz - result lag, so maybe here is a problem also?) :

https://prepar3d.com/forum/viewtopic.php?f=6312&t=124001&start=30#p154707 (PANELS_UPDATE_EVERY_FRAME=1)

https://www.prepar3d.com/SDKv4/prepar3d/getting_help/advanced_configuration.html ( PANEL_UPDATE_MODE = 2 , 0-3, I have Academic)

I will check it. Did you notice in WMR sometime this strange behovior even you have max FPS for example?

Here is example. I did it from camera so sorry for bad quality but you can see few this lag here (notice that I have stable 45 fps in this situation):

 

Yes. Exactly this shot but noticeable stutter, like you display freeze milliseconds, and then goes on. Very annoying this behaviour. It drives me crazy that sometimes it is very smooth, sometimes out of nowhere it has this single stutter every x seconds.

We do have exactly the same issue YoYo!

And it does not matter if you have 150+ fps or 90 fps or 45fps. 

It is like P3D is "running to fast" and forgets his legs (VRSTEAM) sometimes

do you guys use UGCX by any chance? for me  that addon induces this kind of stutter at SMALL AIRPORTS because it is scanning the scenery cache at intervals.  you also notice at ORBX airports that the people stop moving for a second.

Means Ultimate Ground Crew X? No, I havent it.

Was worth asking i suppose.

The latest and newest - 457.30 but dont campare Oculus to WMR, both are different systems. Perhaps do you use Sync in Pre render option in VR settings also?

We do have nvidia in common though. Check this out mate 

I don’t think 3000 series has any good drivers for VR right now, but 456.71 gave me a better experience, plus uninstalling fpsVR helped...

Cheers

 

 

I have noticed in single pass, my plane seems to sit a foot or two off the runway/taxi way/ramps now. Kind of odd.

That issues occurs on some airports since latest P3DV5.1 release (prior HF1). If it is single pass issue or caused by something else and only been seen in singlepass, I can´t tell you.

LM is aware of this as we opened tickets at their forum.

Examples are:

KSEA

FACT

and probably more, which I am not aware of at the moment.

But for example this "large lag" from my video from HMD was present also on 2080Ti, so according me its not a driver problem only but I agree drivers (or Steam VR) must be udated also for 30xx... the first my touch with P3D on 30xx was worse than on 2080Ti on the same version of P3Dv5.1 HF1 and the same drivers and SteamVR/WMR.

This is interesting topic for 3090 owners (the same magneta was in P3Dv5 - solution was not using water on Ultra quality, just High or less, but I played on Ultra water in 2080Ti without any problem https://www.prepar3d.com/forum/viewtopic.php?f=6312&t=140306): 

https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/402768/valve-index-missing-dropped-frames-since-nvidia-d/ .

Yep, it could be a case also with drivers ...

I just updated the following due test purposes to get rid of the lag magenta spikes within the farmetimes:

• Uninstalled the standard Intel Chipset-, LAn and WLAN drivers
• Installed new/fresh and up to date  M.Board related Chipsetdrivers
• Installed new/fresh and up to date M.Board LAN and WLAN drivers 
• Updated my BIOS (ASUS ROG MAXIMUS FORMULA VII Z490) to 0901 Version (got this month released )

I am testing right now and will report back if the spikes do further occur. 

Within the present flight they did not, but it is to early to be sure because I had this often that sometimes it was smooth and sometimes it was stuttery.

But for now, 30 min in flight with FSLabs from GCLP to LEMG not a single magenta spike.

I did it few days ago, BIOS, drivers, new W10 even (fresh install before I changed GPU too), the same as it was.

Do you have software for RGB stripes, like ArmouryCrate, or CorsairCube installed? These are also having nasty sideeffects on latency

also I did the following:

Virus Exlusion to runtimebroker.exe! This gained FPS with WMR running but VR turned off. Very interesting. More stable less jumpy FPS now. 

I saw, thet my FPS went down 20FPS (from 150 to 125) only turning on WMR without entering VR.

After I excluded runtimebroker.exe as a process, this gained.

But these 20 FPS do not count in every situation. In my case only when FPS is already very high above 100FPS+.

 

Btw. In some airplanes in P3Dv5 I noticed also too much flashing and "sun refflection" (like strob effect), especially in the cockpit, but also on the surface. I dont know its issue of the model or from P3Dv5.1 HF1... (FYI. and it's not about the strob light on or off)

Hi there. Yes I have this too. especially within the A330 from Aerosoft in my case. Maybe in PBR cockpit textures planes? As I did not noticed at within the A321 FSLabs, which has no PBR cockpit textures.

I will keep an eye on this. 

At dawn and dusk it is more noticeable.

By the way.....Yesterday I turned off my BIOS Intel speedshift and Intel Speedstep completely. Only Turbo is on.

I have smoother experience now.

Did you test this? Give it a try, its a new intel technique (since a couple of years) but seems to have negative output on P3D. Maybe due the shifting of core frequencies everytime.

I did fly 2 days without any magenta lines/ stutters.

No, didnt try it. I think the problem also is in drivers, see this big topic on NVidia. many users of 80/90 reported VR problem like magneta/stutter in other games also:

https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/402768/valve-index-missing-dropped-frames-since-nvidia-d/

I think still its a poor UPDATE sync optimalization in v5 + new drivers issue for 30xx.
