Brief description of the issue:

Since the most recent update (WU XVI), when in VR (Reverb G2), the game will crash either during the final stages of loading into flight or immediately after loading into a flight. The screen will freeze and CTD. A similar issue had started occurring after the previous update but only when loading into, or near select airports (YBAF) but now this issue seems to happen in any location.

You may try disabling Rolling Cache in MSFS, this helped me with some CTDs.

Same thing happening now to me. Since WU16. Have had at least one CTD each sim session with Reverb G2. But possibly because of whatever they updated in the OXR tools for WMR in the MS Store on 1/30. I wonder if I can revert to the previous version that seemed to not have these issues. . .

[stekusteku]

You can switch off usage of the latest preview runtime

[CuzDawg3]

Thank you. I’ll give that a try in the next few days. I had one CTD tonight (and then posted a complaint about it) and then flew 4 successful flights after in VR so not sure what it was that caused the CTDs. I love tinkering so I’ll definitely try that switch. Also, I did shut off, but also restarted my rolling cache at 8GB.

[stekusteku]

For long time I wasn’t believing the reports that rolling cache may cause CTDs. I investigated my CTD cases for many weeks. When I finally completely disabled the rolling cache, all my CTDs disappeared and I don’t perceive any negative performance impact (I’m on 600Mbps Internet link, only small fraction of it is consumed by MSFS).

[CuzDawg3]

I’ll give that a try too. I have fast network too, and FS is on it’s own m.2.

[CuzDawg3]

I shut off “Use latest preview OpenXR runtime” and seems to be back to its old happy self. (No freeze then force close upon pressing Win key.) Thank you!

[stekusteku]

If this was the reason you should avoid applying WMR updates.

[CuzDawg3]

Yep. Unfortunately the MS store doesn’t give you an option to not install stuff or roll back to a previous version. And worse, it’s required for their other integrated apps. (Like the XBox gaming app that typically gets updated when a new FS version comes out.)

[CuzDawg3]

Sigh Never mind. Still something caused freeze up in VR mode when pressing the win key. (Normally could use it before to pop up the desktop. . .)

[CuzDawg3]

Rolled nvidia driver back to the december release (546.33) and turned off the “Use latest preview runtime” in the OXRTools and still sim freezes up on pressing the win key. This is frustrating.

[stekusteku]

Why do you press the Win key?

[CuzDawg3]

I use it to bring up the app slate desktop to look at tools outside the sim. Most of the time it’s for when I need to reference simbrief, other times for the few FSE flights I’ll fly, for starting/adjusting FSLTL injection, and for adjusting the sensitivities on the HF8 software.

You may consider buying AllInOne tablet by Flightsimulator.me. It allows bringing to VR the desktop of another PC (I use old notebook) via VNC protocol. You can control the apps on the other PC using the mouse of your main PC (in VR). Then you can install your apps on the other PC, offloading the main sim PC. Many apps can communicate with the sim while running on the other PC via SimConnect or GPS position reporting (I use Xmapsy for this).

I run on the notebook:

• VATSIM vPilot remote
• web browser
• SkyDemon real-world VFR navigation app (getting position updates from the sim via Xmapsy tool)

BTW FSLTL has a control panel accessible directly in VR.

You may also consider lowering the resolution of your WMR desktop. I used to do it by attaching second, old monitor to my sim PC and by linking the desktop displayed by WMR in VR to this second monitor set to lower resolution. Maybe the resolution of the desktop you bring to VR somehow overloads your system.

There is also FSDesktop tool (demo version available) but in my opinion it never matured enough, not even close to AllInOne tablet.

[CuzDawg3]

Sweet info! And thank you. I tried FSDesktop many many moons ago and discarded it too because of the lack of maturation. I’ll definitely look in to that AllInOne tablet as that sounds like a great solution.

[CuzDawg3]

Also fwiw, it worked just fine today. Only thing I did was reset the OXRToolkit Companion app thing (in sim) to default and reset everything back to the way I had it again. Intermittent failures: the favorite kind of any tester/debugger/troubleshooter.

[CuzDawg3]

FWIW, OpenXR, the XR Tools, and nvidia drivers were updated again yesterday (2/13). Running that runtime (113.2402.9006) and the latest Nvidia driver (551.52) and now everything works better than before.
