Someone test 5.1 HF1 in VR maybe?

Something new here?

flying now, first impressions v good, no pixellation of skylines yet, no strange 'auras' around trees, very smooth and nice skies. i'll keep testing in different locations and seasons etc.

auto exposure works in vr now

hi

apart from the Robinson i ONLY use 3rd party aircraft so i don't think it's that.

maybe you need to have a look at your settings, here's what i've found applies to MY system using VR:

Autogen draw distance is the biggest framerate hit - set it to LOW.

Turn OFF dynamic reflections - they aren't needed with PBR models.

Higher pixel densities affect latency when looking at panels.

Tailor your settings to your aircraft - If flying a complex jetliner turn autogen buildings off and trees to low etc.

if you have a decent graphics card you can set opaque shadow texture size to 4096, vc texture size to 4096, high res textures to ON, and use TEXTURE_SIZE_EXP=9 in your config and the sim looks lovely.

here's the display settings i use for High Performance Aircraft.

Thanks, will try these tonight when I install new HF.

I tested v5.1 last night again, and VR experience in far worse than in v4, it's unflyable even with default aircrafts with EA on. EA is the only reason I would use v5, but with it fps is around 50-60 (truesky clouds on high), and in VR fps is 50% worse logically, so around 25 usually, a stutter fest. I'm using single pass method in the options, and also tried SteamVR vs Oculus, no difference. Using moderate settings for autogen, both trees and buildings are on normal (sliders on the middle), autogen visilibity low. I really don't want to fly without autogen as I'm using FTX Global, and also I don't wanna use EA clouds on Low, as visual immersion is the key with VR, can't really see the point of flying around white blurry puffs. 🙂
In XP11 I can achieve 40fps constantly, and with simple script, fps is locked to 40 with forced ASW, it's super smooth.

WindowsMixedReality VR Single pass mode

I see within VR Singlepass all the dynamic lights are rendered wrong. It is like they are rendered in one eye (I mean it is left) completely (as it should) and in the other eye as follow, depending on the angle/distance from the lights:

No dyn light visible in one eye (thought it is the right eye)
Dyn Light partially rendered (like they become "cut off" to the right sight of the lights

This is visible at Dyn lights from airports (Like EDDF, LEPA, etc.) and on Addon AI planes like those from OCI AIGAIM I am using. Especially the Logo lights are very good visible and wrong rendered.

This is visible at all FPS ranges, also above 200FPS (Test FALE Airport with DynLights but less demanding on GPU).

I tested all possible SteamVr Modes with no influence on this (Legacy Reprojection mode on/off, Motion Smoothing Enabled, Disabled, Forced on, different SS settings with ranges between 75% - 200%)

Thanks for any feedback.

hi

do you get good framerates with EA off?

oculus debug tool has options for showing performance information in your headset while you fly, might be worth testing various sim settings whilst watching how they affect your vr performance.

for scenery, if you tick the box 'use high resolution terrain textures' stick to these rules (posted by a LM dev a while ago)

For default 256:
HIGH_RESOLUTION_TERRAIN_TEXTURES=0
TEXTURE_SIZE_EXP=8 (or not set)

For 512:
HIGH_RESOLUTION_TERRAIN_TEXTURES=1
TEXTURE_SIZE_EXP=9 (or not set)

For 1024:
HIGH_RESOLUTION_TERRAIN_TEXTURES=1
TEXTURE_SIZE_EXP=10

Please do not use these setting combinations as they may cause problems:

HIGH_RESOLUTION_TERRAIN_TEXTURES=0
TEXTURE_SIZE_EXP=9

HIGH_RESOLUTION_TERRAIN_TEXTURES=0
TEXTURE_SIZE_EXP=10

HIGH_RESOLUTION_TERRAIN_TEXTURES=1
TEXTURE_SIZE_EXP=8

also, it's a long shot but in your simulator SOUND menu check that the devices are not just left as 'default primary device', assign to the specific sound devices you are using.

this makes a difference on my system.

all the best, pete.

Yes, With EA on I have now near the same FPS like without but..,. Personally I prefer to turn it off for VR flying.

same here, no FPS hit. i love the look of the clouds in standard weather (but not the spinning!) but EA gives a certain 'feel' which i like also, really works well with pbr textures. i find auto exposure too harsh for the daytime but amazing at night with EA.

Its a single pass "feature" not for solving according me. You will see all lights in stereo mode when the picture is randered for two screens, not like in single pass for one only (and double virtually for both after this).

Hi,

I will try changing sound devices in the options, will select Rift S instead of default. Who knows, P3D is a strange beast.
Last night I did another test, and I was stunned how bad fps was, 15 to 25 with default Cub, medium settings for scenery, EA on, single pass. More stuff I change, fps is getting worse. When I turn EA off, fps was fine, but visuals simply are not acceptable for me. I will test also cfg tweaks, but as I don't have so much time lately since I have more work to do regarding soundpacks, I'm kinda losing my patience with P3D in VR. So I will either use v4 or stay with XP11 for my private simming needs.

OK understand.

Try also:

When in VR, Start P3D. VR ON, set your HMD on. Take your HP Reverb controller. Press Thumbstick". IN VR you see a menu. Go to graphics and with the 4 options:

SteamVR per app setting

Motion Vector

Auto

Disabled

Press thumbstick and watch the results. You have to turn the menu off by pressing the thumbstick to see the best performance.

I tried this Today. The fact, I didnt know this option in WMR (personally I dont use controller) - but it's not helping for MR on 3090 and ultra water. I tried all options with MR in SteamVR and WMR directly. This ultra water settings is a problem.

Btw. someone has it (Envshade) https://secure.simmarket.com/toga-projects-envshade-p3d.phtml and use for VR flying with P3Dv5.1?

Id like to know how the water looks with this in VR (but high or less water settings in P3D). Default water (with REX Texture direct even) looks very poor in VR, it has very strange 3D effect and plane on the water looks like in the "air". Ultra water is ok but its unplayble for me (big problem with Motion reprojection, FPS are jumping a lot).

I used PTA for P3Dv4.5 but now owner of PTA completely left this market so no any update for P3Dv5.

Maybe water from Envshade and his shaders looks better than default?

i used envshade with no problems prior to 5.1, but now with EA i just get a white cloudscape: no panels, no plane, nothing, as though you are looking into fog with no way out!

had to reinstall the P3D client to fix it, tried it twice but now uninstalled it as unuseable for me.

one other person reported the same problem on their forum but i havn't looked into it further.

EDIT apparently there's a fix https://www.togaprojects.com/forum/envshade/single-pass-vr

I at least posted this on their LM Support Forum. You should reply there that you have the same issue as well. Here is the link and it would be great if you post your issue also. Because the more are posting, the more attention we get.

Thanks a lot.
