Landscape rendering with PICO 4

[-=LE=-LazyEye]

I´m having trouble with rendering landscape when in VR, the ring around the plane is no more than maybe a couple of miles and outside the ring the textures are like looking through mayo or something and that doesn´t give the flying much satisfaction.

I´ve played around in the presets like mad, from low to ultra, landscape detail from normal to x4, draw distance from low to max, filter from normal to sharp and so on.

 

I dont see much differende between them and currently I´m using the following presets:

Ultra

Shadows off

Mirrors off

Distant landscape x4

Horizon draw distanse 100km

Landscape filter sharp

Grass off

Clouds medium

AA x2

Gamma .9

SSAO and HDR unticked

Sharpen ticked

 

And I´m using OpenXR toolkit to override resolution, set coulors and to resize the cockpit to more realistic size and so on.

 

Computer setup:

AMD Ryzen 9 7900x @4.7 ghz

32 gb ram @ 4800 mhz

Rtx 4700ti GPU 12 gb

 

Also been fiddling with VD settings with no avail. 

 

Is there a way to force the game to render sharper images outside the bubble? cause now its like hir res inside the bubble and no res and very blurry outside and that bums me and the experience. Any mods that takes care of it?

 

I bought the game through steam on sale for around ten bucks. Is there a way to see if the sim is updated to newest patch? how do you update it?

 

I´m flying MSFS 2020 with good performance with this setup.

 

Hope you guys have a magic solution for this :D.

What headset are you using and what is the upscale resolution set to on open xr toolkit?

[Koziolek]

The title says Pico 4 so I think it is a safe bet he is using Pico 4 ?

I´m running with a Pico 4 and 1200mbit connection, override resolution 3560x3560 and upscale 2570x2570 at the moment I believe.

Have you played around with the startup file? I use these settings with my Pico 4:

 

[KEY = graphics]
    3dhud = 0
    adapter = 0
    bloom_enable = 0
    canopy_ref = 0
    desktop_center = 1
    detail_rt_res = 4320
    draw_distance = 1.00000
    far_blocks = 1
    fps_counter = 0
    fps_limit = 0
    full_height = 2160
    full_width = 4320
    fullscreen = 0
    gamma = 0.90000
    grass_distance = 100.00000
    hdr_enable = 0
    land_anisotropy = 1
    land_detail = 3
    land_tex_lods = 0
    max_cache_res = 1
    max_clouds_quality = 0
    mgpu_compatible = 0
    mirrors = 3
    msaa = 1
    multisampling = 1
    or_ca = 0.00000
    or_dummy = 0
    or_enable = 1
    or_height = 3056
    or_hud_rad = 1.50000
    or_hud_size = 0.75000
    or_ipd = 0.05272
    or_render_eye = 1
    or_sipdc = 0.00000
    or_width = 3056
    post_sharpen = 0
    preset = 3
    prop_blur_max_rpm_for_vr = 155
    rescale_target = 1.00000
    shadows_quality = 4
    ssao_enable = 0
    stereo_dof = 5.00000
    vsync = 0
    win_height = 1440
    win_width = 2560
[END]

 

Also there is a Pico 4 user experience thread where some of us discuss our settings. A lot is hardware dependent though, but its a good place to start. OpenXR (for me) gets a higher resolution that is smoother than SteamVR

That works out as a 72% scaling. It might be a bit too much. I find the image gets "mushy" if the upscaling is too high. Have you tried 3120 (godlike) with 80-85% FSR in OXRTK? This would give you a similar rendered resolution. 

 

I have also been playing around with various settings and using VD "high" with SGSR to upscale to Ultra and it looks similar (subjective) quality to Godlike and 80% FSR in OXRTK. I can maintain 72 FPS in most situations.

Intriguing,

I tried this but it becomes Shimmerfest 2023.

Any idea what makes the shimmer?

 

Thx

Shimmer is a big issue in VR. I solved this with my rift s by using the landscape blur filter. I believe others have found the landscape sharpen filter works with other headsets. There is discussion somewhere on this forum. With my Pico 4 I can leave the filter off with MSAA set to x4. Maybe also try without "sharpening" ticked in il-2 settings. I think it is a bit harsh. You can fine tune sharpening through VD or OXRTK. 

[MrBlindspot]

Well thank you.

 

Maybe with vd to high msaa  x4 doesnt kill my framerate too much.

An update on this. Having played with this a bit more today, godlike and 125% FSR scaling in OXRTK appears to work best with MSAA x4 and blurred landscape filter.

[MrBlindspot]

My lord, that works wonders in the shimmer department.

 

I keep this for a while and try to find a nice colour setting.

 

Thx dude

What are your specs?

 

And what FPS are you getting with this setting?

I have a 5600x and rtx 4070. 64gb 3200 ram and a fast NVME drive. 

I have the game set to ultra and most settings maxed out. I use OXRTK for sharpening and colour/contrast adjustment and FSR 125%.

I get 72 FPS with the headset at 72hz. No ghosting or stutter. It only drops below 72 fps when low to the ground above a town/city. I've only tested this in single player so far. I imagine MP will take a bigger toll.

Whats your override resolution set to?

I have not overwritten the resolution. I have just left it as it is set in VD (Godlike). I'm not sure why but it seems to look better than if I override the resolution in OXRTK.

Allrighty, I´m gonna try your settings tonight and see what happens.

I tried and shure glimmerfest is over ? but I don´t really like the cartoonish ground but I guess thats something we got to live with :D.

Ok cheers, I am going to give this a try. Are you on a wireless connection? 

 

And what would be your startup.config settings? If you don't mind sharing cheers.

 

You report no ghosting! That's what I've been chasing

I use a powered Ethernet to USB adaptor and a cat 6 cable to connect the headset to the router. You can then turn off WiFi and connect direct. I get more consistent and higher bitrates. 400mbps with h264+; 150 Mbps with 10 bit HEVC.

Try running at Godlike with no scaling. That should look a lot better but it will give you a performance hit. Maybe try turning off MSAA.

Already running Godlike in VD and always did ?.

I´m comparing IL-2 with what I get from MSFS2020 but maybe I shouldn´t? MSFS has far more better almost real scenery after I nailed the sweetspot with my tweaking.

Got it running pretty decently now, I changed my ethernet/charge hub to the headset, charger, and the cables from the charger and from the hub to the headset, next thing I think I´m about to do is to change the ethernet cable to a cat6.

Currently I´m in Godlike mode and 100% charpness in VD, Ultra in game, sharpness unticked, msaa x4 draw distance 150km and the rest of the settings like mentioned in OP, oxrtk override 3172 and upscaling to 85%, playing with sharpness between 35-100% but can´t say that I see much of a difference, changing the colours back and forth to get a more world like look.

 

In Nvidia settings I set anistrophic to x16, rest is more or less programcontrolled except for a couple AA settings ( not in front of that computer so can´t say exactly).

 

Got it running pretty stutter free with around a 16 plane sorty, woooohooooo.

Seems like you guys are getting good results with USB C to Ethernet as apposed to wireless connections. I may be able to find an adaptor at work to try it out.

It´s far mre stable than wireless and you get the headset charged at the same time. I would strongly recommend to get an adaptor, it´s a no brainer to hook it up.

I had problems using a USB hub which had HDMI, USB and a gigabyte Ethernet. It turned out the Ethernet port was only giving 100mbps. Make sure it is working as intended before dismissing the experience. I replaced it with this and it works flawlessly.

I got the ethernet adaptor going no problem, and yes it is more stable. I can see the gain. 

 

Compared to my solid wireless connection (dedicated wifi 6 router positioned 3m from the headset):

 

Benefits are:

• h264+ @400mbs is smooth. No stutters
• Ghosting is less, but still exists in those moments where another aircraft is rapidly crossing your flight path. (this for me seems to be a bit of a immersion killer and bugs me - others probably not)

Negatives are:

• Corded! A loss of freedom being tethered is noticeable.
• potential battery damage.
• I've had two head unit freeze events. That never happened wireless.

 

With a 4080 using MSAA = 1 (so really 2x) i get up to 90 fps, but with MSAA = 2 (really 4x) i still cant elevate past 60. So i keep it to =1. 

 

Latency is also not bad using this method.
