for Quest 3 users : passthrough screen readability (helios compositing)
-
Mike,
Awesome job, can you share your helios setup. I have 2 screens, but the vr displays on 1st and 2nd monitors(mirrors) and I don’t get the view port displays on the cockpit. Plus it’s really shudders when I move my head. I have a 4090 and top tier pc. I just started vr , so not familiar as much as I want to be. Thanks.

@scottd5800 Hello,
I’m using Ice’s profile you can find here :
https://forum.falcon-bms.com/topic/20238/ice-s-falcon-bms-profile-updated-for-bms-4-37You can’t be in Mirror mode, you need to right click on your desktop >display settings and choose extend this screen instead of mirror.
Be sure to read Max’s post for a few VR improvement:
https://forum.falcon-bms.com/topic/23871/couple-notes-to-vr-usersAs a note, this “solution” requires one more layer “VR Reality mixer” that’s a payware and as Max said above to me we won’t need that software for U4.
I would suggest you to try to get your vr setup smooth first, then have it smooth with helios running and only then try the mixed reality stuff. It takes time to optimize VR and I’m nowhere near close to the performance I want so I can’t help on that part. -
@Mikyjax Thanks. I have reality mixer and can get passthrough. Silky smooth without reality mixer running, with running, slight jittery when moving my head, seems not to like it as much.
On helios, I use it all the time and quite familiar. For some reason in vr , the view ports don’t display ,.because normally background is black and view ports populate. I get the monitor background without viewports, I also get telemetry, a little laggy. If I use the it , non vr, everything works great. Not sure if I missed a step? Thanks and that’s my goal to get what you accomplished. This is my first time vr, wow I can’t go back! So realistic!
I have RTX 4090, and very beefy PC…so i can achieve extremely high settings with super smooth visuals,.it’s the reality mixer layer that adds the micro stutters, when moving head only.
I just got to figure why my helios is not showing viewports (yes, I don’t have the 2 monitors mirror, I have them extended mode)
Thanks for any ideas or suggestions I might have missed.

@scottd5800 sorry, I didn’t get what you asked. I think the jitter (that I also experience) is due to the camera refresh and the sync with the game. Not really a way to avoid it right now.
do you have the line with RTT in your config file to populate the mfd’s? is that what you mean by viewport?
I think there is a limitation in helios where it’s only refreshing half of the game FPS, and in vr it can get quite low, especially on the ground.I did play with Vsinc on and off and it seems to improve it a bit (not sure why)
Did you completely follow the setup guide for ice’s profile? If you are using a different one I can’t really help as there are a few ways to get data into helios and I don’t know much about it, that profile worked directlyYeah, VR is crazy…
-
@Mikyjax Thanks. Are you running 2 monitors? helios on non primarily screen? I use helios all the time, but never in vr applications. So it’s weird, because non vr it works as advertised, in vr, it shows up in 2nd screen, populates the screen, telemetry, but no viewports. Anyhow, Thanks for responding, very cool application. I think this will be greatly modded and improved. Awesome!

@scottd5800 yes helios is on my secondary tactile screen, I disabled the mirror view in vr.
-
@Mikyjax Thanks, I think that’s the problem. How specific do you disable mirroring in vr, like screen shot, if possible. Thanks!

@scottd5800 I think it’s this command, paste it in your user config:
set g_bVRNoPresent 1 -
@b0bl00i Thanks, I got helios working. Reality mixer just kills the smoothness, like very tiny jerky moving head around …
No Reality mixer, it’s absolutely stunning and smooth
Helios is a little choppy.
I tried Helios dcs, and I can’t get viewports to populate (I know this bms, But trying different sim) Has stuttering with Reality mixer…we are so close to AR!
