Bones308th Posted September 10, 2019 Share Posted September 10, 2019 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! Ray Link to comment Share on other sites More sharing options...
Baldrick33 Posted September 10, 2019 Share Posted September 10, 2019 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?

Bones308th Posted September 10, 2019 Author Share Posted September 10, 2019 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 Link to comment Share on other sites More sharing options...

Bones308th Posted September 10, 2019 Author Share Posted September 10, 2019 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 Link to comment Share on other sites More sharing options...

Baldrick33 Posted September 10, 2019 Share Posted September 10, 2019 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.

Bones308th Posted September 11, 2019 Author Share Posted September 11, 2019 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.

Kirin Posted September 11, 2019 Share Posted September 11, 2019 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.

As I mentioned I have gone back to the stable versions of both WMR & SteamVR, because I found the FPS was jumping around. Bear in mind every time you change between WMR stable & beta the settings file needs to be edited to enable reprojection. Hard to believe this isn't a GUI option but so be it!

Bones308th Posted September 11, 2019 Author Share Posted September 11, 2019 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?

Baldrick33 Posted September 11, 2019 Share Posted September 11, 2019 I don’t see a color indicator on the Reverb Pro. BonesJust to clarify the indicator is in the top left of the display as an overlay, so you should see it while flying. If it not there then it sounds as if the right file hasn't been edited correctly.

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.

Bones308th Posted September 11, 2019 Author Share Posted September 11, 2019 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.
