HP reverb Gen 1 Stutter

[comie1]

Having issues with stuttering horizon and view in the HP reverb gen 1. Haven't been able to fly since April. Previously the pixel density at 0.5 and Steam VR at 500% made the game feel like DCS 3.0 it was so good, a patch or two later I can't play on any setting. Have tried everything I can think of and every setting I can in both DCS and VR settings.

Running latest Open Beta testing on F16 free flight. FXO and metashaders deleted and fresh DCS install.

Frames (ingame display) low 51 high 90

Drivers all upto date

PC Spec 

CPU i7 6700k oc to 4.7GHz

GPU Aorus 1080ti

Ram 32Gb

NVME SSD

Attached screenshots of settings and settings files from DCS

Any help would be much appreciated.

Have you got motion smoothing enabled in the wmr menu in steamvr?

Also change your GPU power profile to maximum performance.

Hey, Yes I have tried motion smoothing Enabled, Dissabled  and Forced with either worse or same results.

GPU is unlocked sir

Its not the motion smoothing on the steamvr menu, it's in the wmr for steamvr, the options should be enabled, auto, motion vector and disabled; I leave it to auto. The steamvr smoothing is a red herring when using WMR!

Your GPU settings show that you have optimal power for the GPU, set that to performance, optimal power tries to save power by gimping the GPU

Attached photo is my GPU power settings, changed the Nvidia setting now tho

I'm sorry I don't follow this WMR steam Vr setting? Where am I looking?

Thanks comie1

Can you attach your dcs log also from your saved games dcs log folder. 

As edmuss mentions the wmr settings can be accessed when you start steamVR and you have the little popup window, you can select windows mixed reality for steam options and adjust.

It maybe worth renaming your dcs folder in saved games ( keep it as a backup ) and allow dcs to create a new one, then login and redo your settings a test. 
The fresh folder should have no tweaks, unofficial mods or edits for testing. You can always go back to the backup if needed or move stuff from there to the new location after.  

make sure maximum performance is selected in the nvidia control panel

Dude.... I had that little window dissabled, Had no idea that setting existed. OMFG you LEGENDS!!!! Fixed

Awesome, you're in the fps range that motion smoothing is largely essential to keep the janky away. Unfortunately it's hidden away in that menu!

If you go into the developer menu in wmr for steamvr and enable the motion smoothing status it will put a coloured square in the bottom left corner of the screen. The following is from a message I typed earlier so it's easier to copy and paste than do it all again

"If you enable the smoothing status from the developer tab it will show what the smoothing is doing. Green is above refresh rate and smoothing is off, dark blue is below refresh rate but above threshold, light blue is CPU bound (I think) smoothing, red is smoothing off because you're below 55% of refresh rate."

The wmr smoothing is disabled once your framerate drops below about 55% of the refresh rate (~50fps for 90hz ~33fps for 60hz). As you're on the cusp of the threshold on your low fps then switching the headset to 60Hz refresh will give you a massive chunk of gpu overhead to allow you to increase details and settings to improve visual quality. The downside is a more visible refresh rate flicker, I noticed it for about 20 minutes but cannot see it now at all. Try it and see, you may be fine with it.

I also find that the wmr performance mode and upscaling gives massive reduction in visual quality in the G2, your gpu may struggle to push it through at full resolution and quality but the switch to 60Hz may well allow it

Edmus you beautiful person you xxxx

I've tried 60Hz and it sucks unfortunatly. new PC coming soon which will be a helper in pushing the frames etc, but I care not now I can finally fly again!!!!
