FS2020 VR + Pimax Discussion

The 150/152 series is tiny- it’s definitely designed for 1950’s sized pilots. The useful load is tiny- basically if you want full fuel, you need to be about 180 pounds or less with a similarly sized passenger. I did most of my training in a 150, and I towed gliders with a 150/150 with vortex generators and a Horton Stol kit. Now THAT was a cool airplane. But I did get nervous on a hot day with two big guys in the glider behind me! It doesn’t feel quite as cramped in FS2020, but to my mind, it flies similarly to what I remember- but adverse yaw and p factor appear to be missing. Realistic mode feels pretty gamey. Nice stall horn tho’! I’m uploading a video on my youtube channel doing the High winds landing challenge in Sedona. I have to say, it’s a lot of fun! It needs some tweaking both from me and from the designers, but so far, FS2020 VR looks like a winner to me.

Too bad (2080to i9 9900k) performance GPU 65% CPU 31% ^^’

What is your GPU and is it OC? What is your FPS?

Can you try with different headsets and see if it is small in every one of them, or if they differ?

There are (as you have guessed yourself) other factors which influence the depth perception (and the size), and those are mostly related to the optics and geometrical verity of the displayed scene. Which depends not only on correct IPD but also the eye relief and the correct pre-lens warp distortion function. If those do not match you can observe it as a different geometrical errors.

The problem is there is no “worldscale” solution to this problem. So unless there is really some inherent problem in MSFS (which I would guess is less likely) the problem lies in how good is the headset together with how well the headset matches your individual facial features.

im not sure you are correct the “worldscale” in DCS manages pretty well even if it is labelled incorrectly as an IPD adjustment. ive owned both rift and pimax and the DCS setting worked in both headsets the same way and others i know who have hp reverbs report the same.

Either FS is very poorly optimized or I’m doing something wrong. I have all Pitool and SteamVR settings to the lowest possible values and I’m still getting high 30ms frame timing. Also, GPU utilization is only 6%!!!

Anyone else experiencing this?

I can not compare with other headsets. But what I know is, that the IPD setting in DCS-World or the “scale-factor” in aerofly FS2 adust exactly that roomy or scale feeling in the cockpit. In DCS it’s very easy, because you can compare the arm lenght of the Pilot figure from the sim with your own arm…

You certainly have something wrong.
I have a Pimax 8k+, i9900kx and a2080ti, and I have between 30 to 36 fps most of the time.
Of course not flying over New-York, but “standards” landscapes it’s fine.
And beautiful.

Don‘t they actually aim for 30 FPS in VR, which they then interpolate to 90 FPS with a special reprojection mode ? That would possibly explain why you don‘t easily get higher FPS… but I have decided to park FS2020 for the moment, it has great potential but performance needs some more polish, it seems.

I am not that familiar with DCS to know how IPD setting works, but it is true for any headset that if you change the virtual camera distance (which I believe is what this IPD changes), you will observe it as a change in the size and also in the depth.

The “only” consequence is that these will no longer match your IPD (unless the in-game IPD compensates for some other in-game geometry/IPD problem) and therefore will not be true. In other words it is a hack, but not a solution. I can however imagine that it may suffice in some specific scenario.

If this is your intention, you may try to change the IPD offset in PiTool and see if it produces the similar effect. It may or may not, depending on how exactly Pimax uses this IPD offset, but it will definitely skew the geometry one way or the other.

ok here goes im certain ive sorted out my issue

the fix was to start steam vr through the pitool app then i run the game thruogh geforce experience (not 100% this part is needed) but i now get this

very happy with performance and no jaggies just in vision on my right eye.

The hidden area mask (the black borders filling the rectangle) corresponds to the parallel projection mode. The one you had before was the native mode with canted rendering cameras. Sometimes the headset may get stuck with one mode even if you switch it in PiTool (at least my 5k+ does that), then the solution is to reset the headset and/or the Pimax background software (restart PiServiceLauncher.exe service).

Wow, I was having the black boxes and trying everything. Finally did the room setup and chose sitting only, quickly did the setup then hit CRTL + TAB in MSFS and viola. No more black boxes.

If you have black boxes, try doing the room setup in Steam and choose sitting only for now.

where do you guys find these?:
"

  • Turned off game mode + hardware accelerated gpu scheduling in Windows
  • Turned off G sync
    "

and from my experience - 2080 nvidia, 32 gb ram, ssd and i7 8700 cpu 4ghz, pitool 1.0.1.266 and newest nvidia drivers, performance is just crap. no idea whats going on.

Its like 2 fps / sec. and i am sure its not bcz of hardware. this must be a software issue. The problem is that once i run pitool / steam vr, performance starts to decrease, the game menu in general has like 2fps/ sec! yeah - cant even navigate in game menu!
right now i am downloading some content - so MSFS is up (dropped on the taskbar), pitool up (taskbar) steam / steam vr up (on taskbar) and my mouse cursor is super jittery, takes ages to type anything in web browser and the whole pc performance is garbage! without vr and pitool i can run that game on ultra without issues! this whole vr stuff is messing up everything.

in game - cessna cockpit feels way too small. my head is through the roof. literally, and my seating position in game is behind the cockpit seat. yep - i am sitting behind the seat. no idea whats going on and how to increase interior size and how to change seat position. i have 2x base stations v2.0 working fine. in alyx, beat sbaer etc scale is perfect. in MSFS the scale is off…any advice appreciated!

Mine does not work at all! I am very disappointed. I have the 8kX When I put fs2020 in vr mode all I see is two images really tiny really far away in the distance. Pressing the reset vr button does not help. The compatibility with Pimax headsets is not very good, many developers do not support it. I hope Pimax contacts Asobo and gets this fixed ASAP.

These both are Windows settings (the latter from version 2004).

G-Sync is a driver option (Nvidia), but it is only available on a monitor which supports it, not on the headset, which typically: a) does not support it, b) is not exposed as a monitor in Windows.

After you done room setup in pitools, switch to standing mode in steamvr room setup.
My 8KX issues are gone.
When I switched back to room scale mode, I get out from virtual space to black box in MSFS VR.
Try that!!

Anyone know if there is a way to zoom when in VR? Or is this not implemented for VR?

So apparently using the latest OpenXR you can get much higher performance in this game. You can tell the game which runtime to use by editing a json file.

Wasn’t Pimax supposed to have an OpenXR runtime?

Also, apparently they have figured out a way for smoothing to interpolate on thirds. So 30fps feels like 90

Wasn’t Pimax supposed to be working on something like this with BrainWarp?
