Hi Sprung, if you are responding to my post, it is VD’s SSW I’m using.
Re oxrtk crashing - I don’t think uninstalling OXRToolkit removes it’s registry entries which is a pain if there’s a bad setting causing a crash. I saw a post a while ago where someone asked MB how to remove them from the reg.
I’m okay with some wobbles. I’d prefer the clear but sometimes wobbly bits, than the ghosty doubled frame appearance.
yes it was to you. SSW has bothered me since 2020. the HP reverb G2 had great motion reprojection. SSW was bad on my Pico 4, and now Quest 3, I will go play with it. VD 1.33.3 just increase performance again reducing latency, so I’ll try it but I just saw Limitless VR video and he’s using VR flight sim guy settings with SSW and I can already see the wobbles.
Mbucchia knows a few things and so I would heed his warnings.
Any particular settings for 4080, 7800x3d and pimax crystal light ? Last I used it was creating abnormal stuttering from time to time
This is why HugeMercury told you to use the Safe Mode, where settings are ignored. You can then go to the Menu Tab and do Restore Defaults in order to delete the settings.
Hi, thanks and yes I have tried this but on one of my systems it still retains the settings for me after restoring the defaults. It wilI clear the settings if I perform the default shortly after installing OXRTK on a system that has never had it installed, but after using it for some months something seems to change and will no longer clear them. (DCS, Assetto Corsa, MSFS 2020 in my case)
I did a search for your earlier response to another user who was also asking but haven’t been able to locate it. I can’t recall if it was on this forum or discord?
Would it be possible to share here how to manually remove the entries?
You need to answer the “Confirm” prompt that appears immediately after.
You can delete the registry keys too, HKCU\Software\OpenXR_Toolkit.
Thank you, I’ll give that a try tonight.
I am also seeing intermittent stuttering with the crystal light.
One minute everything is smooth then bam, its like its at 3 fps for a few seconds.
What was weird was during one stutter fest, I deactivated VR and the Pimax default screen was also stuttering lol.
Which I knew what that means.
Me too. A lot of stutter that i solved (i think) as soon as i disabled the OpenXR toolkit.
On the problem system, I only have an openxr_toolkit entry under HKLM but no actual entries/keys. However, I’ve found them in your path on my fresh install. I’ve added them to the problem PC using your path and it it’s now allowing me to clear the changes in OXRTK.
Thank you for sharing that 
Cheers
I’d had stability issues since launch - Reverb G2. Weirdly more when using the menus or at the end of missions than when actually flying.
Disabled the toolkit before starting last night and managed 7 hours continuous use without closing or crashing. This despite exiting and re-entering VR several times, both deliberately and when the headset went to sleep.
That’s a more stable experience that I think I ever had in 2020.
I am using OpenXR Toolkit 1.32 IIRC with override resolution set to 5,000 with mostly Ultra graphics in VR. Latest ver. DLSS set to maximum performance. No problems and very sharp graphics inside and outside the cockpit.
5800X3d, 4090, 32GB ram, Windows 11, Varjo Aero
35 fps over New York and London, 40 fps over less demanding areas.
Those of you who have a stable system with OXRT, can you please check if you have foveated rendering enabled?
I’ve started with default settings and it was ok, but then the system crashed shortly after I had enabled it. Just want to figure out if it was a coincidence or not.
I used the Toolkit both with and without Foveated rendering, stable either way.
NIS Sharpening? (The other option I have active)
I have enabled with preset.
The Openxr toolkit is essential for good performance in MFS 2024 with my 3080 and Pico 4
Yeah I know, I’m not sure what causes it to crash - all good in 2020
I have FSR enabled. I’m not through tweaking, will try NIS and also other setiungs in the sim and in the Toolkit.
Not sure if anyone has mentioned this, but for Pimax Crystal headsets (not the Crsytal Light) the Toolkit is essential to run eye tracking Dynamic Foveated Rendering. If you disable the Toolkit and try using DFR via the Pimax Play client it won’t work in MSFS or MSFS2024.
To quote Oniwhatever on the Pimax Discord server:
“You must have the OpenXR toolkit running with DFR or something, because Pimax’s injection of DFR only works with OpenVR games/SteamVR, which MSFS2020 is not.”
Since I get a nearly 10fps boost using eye tracking and DFR the Toolkit is a must right now.
