HP Reverb Stutters

Hey Guys,

Just got the HP Reverb, and I’m having stutter issues. I have a i9-9900K with the NVidia 2080Ti setup, and is stuttering quite a bit. Especially noticeable when moving my head from side to side, in the pit! I’ve checked settings but kind find if this is a limitation with the headset, or if I’m missing some settings. I also noticed my frame rates bouncing all over the place, from 45 all the way up to 90! This is a show stopper for me with this headset, as it gives me a light headache. It sucks! I was running the Oculus Rift S and that thing was glass smooth. Please let me know what I can check, because I’m seriously considering returning it. Thangs guys!

A couple of things:

Are you running the stable or beta versions of SteamVR and Windows Mixed Reality for SteamVR?

Have you edited the settings file in WMR to enable reprojection?

Hey Baldrick!

Thanks for the quick reply man. I’m running Steam VR Beta, and WMR for SteamVR. The enable re-projection stuff, I have no idea! I have to check and get back to yah! Thanks man!

Ray

Okay. Reprojection is On.

Ray

It does show as having Motion Smoothing as off, but I can’t find where to turn it on. Maybe that’s the issue?

Ray

Enable the indicator for Motion Repo (in the same file where you've enabled the same)

Run DCS, does it show a red square?

Motion smoothing is for other devices like the Vive & Index.

I found SteamVR Beta to worsen performance and have rolled back to the stable version. Worth a try.

What?! In the same file? What?! Lol Sorry man, no idea.

Dude, I’ve tried both, and no change so far. Thank you though.

Where would one make this change...location? Thanks

Thanks guys. I’ll check it out tomorrow. I put back my Rift S, and is silky smooth. I mean, I occasionally get some stutters every now and then, but nothing compared to the Reverb. One thing I did noticed is the Rift S maintains a constant 40 FPS. On the Reverb my frames are all over the place between 90 and 45. I had the same issue with the first generation Rift, but I managed to lock it at 45 FPS with the Oculus Tray Tool. I think the jumping around in frame rates, may be what’s causing the stutters. Again guys, thanks. I’ll test it in the morning. I’ll post back here.

Bones, do you see the little color indicator in the top left of the HMD for the status of Reprojection? It's green when reprojection is off light/dark blue when it's on and red when the FPS is below the reprojection minimum. If not, reprojection is probably not in use.

Okay. That has been checked, and it was the same as the red lines posted above. I didn’t have to change anything.

I don’t see a color indicator on the Reverb Pro.

Bones

Okay. Something I noticed. On the SteamVR Settings menu. On the lower left hand side, I’m showing:

Dashboard Off

Chaperone Bounds Of

Reprojection On

Motion Smoothing Off

When I launch DCS, I’m left with:

Dashboard Off

Chaperone Bounds Off

Does this mean anything?

Bones

Use this instead

"motionReprojectionMode" : "motionvector",

Do not use a second monitor, turn it off if you do.

I don’t see a color indicator on the Reverb Pro.

 

Bones

If it not there then it sounds as if the right file hasn't been edited correctly.

Just to clarify the indicator is in the top left of the display as an overlay, so you should see it while flying.

Copy man. Thank you. I’ll look for that later today and let you know. At least for now, I haven’t noticed it in game. I contacted HP tech support today about the issue. They seemed to confirm the issue, and are working on a solution. I gave them the link to this forum as well.

Bones

"motionReprojectionMode" : "motionvector",

huh? Why?

Have two monitors + VR, never any issues.

bones, you have to edit that file by removing the // infront of the highlighted red lines. the removal of the // is the whole point.

Oh shit! LOL! Really?! I freaking missed the boat on that one! Okay. Let me try that! Thanks man! See Yah!

Bones

Okay guys. Here’s the latest: I removed the “//“, and it did make a noticeable difference. However, I’m still getting them. The frame rate changes are narrower after the edit for sure. In other words, instead of swinging wildly between 45 and 90, they’re +/- 5 FPS or so, when the frame rates are somewhere in between 90 and 45. When I get low to the ground and frames are locked at 45, is a smooth experience. Is there any way of locking the frames at 45 FPS? If I can do that, I think it’ll cure the problem.
