4.37 CTD when entering 3D VR
-
I’ve been getting doing some extreme settings with the Pimax 8K X and have had the CTD going into VR 3d world. Most of the time I deleting d3d11.dsp and going into the 3d world without VR on then to rebuild the that file works immediately.
-
Have you tried antialiasing on just 1x instead of 8x? You’re asking a lot from that 1070ti
-
@Dragasath
Tried, with no success.
Initially my assumption was, that performance related settings shouldn’t cause CTD issues, but being the base of F4 as old as it is… you never know… -
Additional info, it doesnt even get to the loading screen.
Th last thing seen on the desktop is the capture below, I had time now to make the screenshot during the dump.
This means it switched the ui screen to the vr resolution but crashed before the loading screen:
-
did you try WMR Beta?
-
@Dragasath
Did not know that this has beta, sadly no improvement.
On the other hand, due to this VR patch I started to fly Falcon again (in no VR… obviously…:) )… I almost forgot how great this sim is… and so different from DCS. -
Hit me up on discord tomorrow, I’ll try to help you out.

@Dragasath
Sorry, its not that easy with family.
Will find some time. For the time being I will try to find the reason behind this crash, as everything else works perfectly, except VR. -
My somewhat similar crashes were fixed by deleting out the d3d11.dsp in the user\config\ and then entering the 3d world without VR to rebuild the d3d11.dsp. Then I could reenter VR with more “reasonable” settings.
May not be their fix, but any harm in trying it since BMS with regenerate the file?

Well, looks like nothing helps, BMS reinstall with all defaults has the same result.
I wont do windows reinstall…
Is it possibe to ignore SteamVR and use openxr?
Or BMS is relying on SteamVR exclusively? -
@Staniol I still don’t have a clue here. But let’s try something very basic first. Please try lowering the VR resolution a lot, like 0.1. Does it reach 3d?

I don’t think you have a BMS problem at all – I think it is more of a Steam VR issue. I was having the same problem as you before I made the changes listed below to Steam VR. In fact your log files and my log files were almost identical before I made the switch in Steam VR.
Look at my solution here:

-
Thanks, but no luck.
I think I just give it up for the time being, and continue to fly Falcon on the flatscreen.
Will go to dcs an Il2 occasionally for my VR itch. -
Sorry to hear that it did not work.
Do you have the Windows Mixed Reality for Steam VR installed?

If not, you should install and try again. Try running the 4.37 BMS shortcut as an Administrator.
This is also important:
Be sure you add this to the end of the target line. One space after the last quotation and then this: --force_steam_VR.
The complete target line should end up looking like this:
“[DRIVE LETTER]:\Falcon BMS 4.37\Launcher\FalconBMS_Alternative_Launcher.exe” --force_steam_VR -
I had similar problems when I switched from my 4090 to a 3080 with a clean installation of drivers. Long story about the 4090 but suffice to say it is on its way back to the retailer as it is failing.
Anyway, your CTD when entering the VR cockpit. Poor performance will most certainly cause a CTD as it has happened to me.
Because I did a clean install, it removed all my game performance profiles. Once I added Falcon back and set the performance mode to prefer maximum performance I’ve not had any problems.
So, if you haven’t got a profile for Falcon under Manage 3D Settings > Program Settings in the Nvidia Control Panel you will need to create on and set performance mode to “prefer maximum performance”.
HTH

Just a small update.
Its the same in 4.37.1.
I am also sure its not related to performance, as it does not happen when entering the 3d world, it happens when the it switches to the loading screen, after I choose ramp, taxi, or runway.
Strange. -
@Staniol sorry, no clue yet about what could be causing this. One thing I remember, I usually have problems when I run Falcon with web browser open. Any chance you have a browser open while playing?
-
@Staniol also make sure you have no VR overlay apps running when you test. I noticed that OVR Toolkit overlays make BMS crash, but certain others work (can’t say for sure which).
-
@Fearripper96 +1 for Vr overlays causing issues. I’ve noticed since u1 that open kneeboard seems to induce a ctd. But OK also updated at the same time or near, so it could be either of those updates that caused it.
why do I think it’s openkneeboard? I do not know for certain that it is, but can only anecdotally say that BMS has not crashed when OK is not running. OK also quite often hangs (the 2D Ui works but can’t get it to toggle display in Vr - it either gets stuck visible or hidden) or just randomly exits
@fredemmott if there’s any useful debug I can provide, do shout.

@rubbra remove Falcon BMS from Settings -> Games in OpenKneeboard. If it still crashes, it’s not OpenKneeboard - it’s then entirely through SteamVR, and it has no other way to interact with Falcon BMS. If OpenVR overlays make BMS crash - but don’t otherwise interact with the process - this is most likely a BMS bug, but could also be a SteamVR bug.
If that fixes it, it’s likely some other software (as well as VR overlays, things like RivaTuner, OBS, Discord overlays, MSI afterburner have similar issues) conflicting. There is no safe way to modify another process, but this is what they all have to do to offer their functionality.
If it doesn’t fix it, it’s not OpenKneeboard.
If Falcon BMS is not listed in OpenKneeboard Settings -> Games, and you have a Wacom tablet, it’ll still work. If you have any other brand of tablet, you either need to trace down which other software is clashing, or use OpenTabletDriver instead (USB tablets only, not bluetooth). If you don’t have a tablet, and don’t want non-VR OpenKneeboard, just leave OpenKneeboard without Falcon BMS listed in Settings -> Games.
