Hello pilots, i have a problem and need any possible advice.

 

i fly with bf 109 and when say another bf 109 is far away from me at a quite long distance, i see its wings to be "fat" like say p-47 or spitfire , when that plane comes to a closer distance i can see it and its ok! narrow slim wings as bf 109 should have. That problem makes identification quite difficult and i suspect that it is due to some kind of image distortion.

 

i fly with quest 2 , use FSR  (render scale 0.8 , sharpness 0.9 , radius 0.5,   applyMIPBias false  debugMode  false ) , ingame AA set to 4xMSAA , postsharpness=0 , STEAMVR final resolution about 2700x2700 ( set 1.5 multiplier at Oculus Tray Tool) , fps about 70 to 60.

 

  Should i reduce AA from 4x to 2xMSAA (possible cause of distortion?) and set a higher resolution than 2700x2700 or in this way i will loose my spotting ability using higher resolutions; 

Is it possible that the ingame VRZOOM function induces some kind of distortion looking at long distances?

 

What do you think?

 

Thank you in advance!

Hi all. I have a Steam version. Can I launch sludge 2 not through the STEMVR, but through the oculus?

[Youtch]

After googling it, i cannot find clear explanation of what is the impact of Overlay Render Quality setting in SteamR.

 

I was wandering which settings would help the game to be more crispy (less blurry).

 

Any recommendation?

 

I am on a combo G2+3080.

 

I have read in old threads that disabling Advanced Supersample Filtering is recommended to avoid seeing plane double with high deflection accross the cockpit. Is it still the case? I will try this new config with ASW disable.

 

THANK YOU VERY MUCH IN ADVANCE

As a reference OK, as a guide for use in IL2 VR then "no".

 

The only nvidia settings that I found to have a measurable beneficial difference in frametime where anisotropic optimization set to on and trilinear set to off and the net benefit at 90Hz was a whopping .1 to .2 ms in frametime, which is nothing great really.

[Youtch]

Overlay Render Quality setting in SteamVR is in SteamVR, not an NVIDIA Setting.

It's the render quality of the SteamVR dashboard inside the VR session.

Sounds interesting but I’ve no idea what “HAGS on” is

What is the suggestion here, to keep it High?

Whatever you want as it doesn't matter since it only affects performance when it is visible and you don't need the SteamVR dashboard visible when you are playing. For sake of rendering clarity when you need to use it or a virtual desktop just leave it on high.

YMMV, I find that it hasn't affected my system's performance negatively for the sims/games I play so I've left it on ever since I upgraded to a 3080ti some months ago.

Have you got distant image enhancement turned on in settings? That enlarges planes far away so you can see them easier.

It is literally only applicable to the in game overlay that appears in steam vr when you press the controller button to change settings/quit game etc. It doesn’t really matter. If you can’t read it then turn up the res.

Ah thanks, of course. I’ve always had that off as everyone has said to do that. I must try with it on in that case and see if it smooths out things in the game. Even though I get a steady 60fps it does still stutter a bit in certain conditions.

If you go to ‘quick mission’ and at the bottom of the map is a settings button. That’s where I find it anyway.

I found HAGS causing increase frametimes and stutter on my part especially in DCS so I leave it off.

You'll need the app Nvidia Inspector,

https://github.com/Orbmu2k/nvidiaProfileInspector/releases

 

Set these, you'll need to activate the Show unknown setting from predefined profiles button to see the settings.

 

What it does on mine is make the contacts and the general world like cities and trees appear more 3 dimensional.

[Youtch]

You changed those 5 settings specifically for IL2? 

 

This seems like venturing quite out of the beaten paths. ?

 

May I ask what initially drove you toward modifying those hidden settings? Were you trying to fix something that was broken?

Aren't those the old settings for "3d" screens, like with blue/red lenses or shuttered lenses?

It was easy, these are from a preset called VRdirectX in the drop down menu, you can try those ones out very fast and reset them on the fly.  There's even a preset for IL-2 Battle of Stalingrad, but it caused the game to malfunction for me.  I tried a few that looked interesting and possible compatible.  This was one of them, and was impressed with the resulting crisp 3D models, its easy to tell exactly what mark of 109 your up against in a close up fight, can see things crisper like antennas and bulges.

[[CPT]Crunch]

It's well worth it, this has quite a dramatic effect on cities, forests, and terrain, not just on aircraft.  You can actually see the size differences in the trees now, it doesn't look like a mono forest of uniformity, and the cities, there's an actual topography to them now where the taller buildings dominate the skyline at distance.  The land is very noticeably rough and bumpy looking where its unbroken and uncultivated at altitude, you had to get down in the weeds to see that before.  This is a keeper, bringing it all more alive.  Don't notice any hit in rendering performance. 

[firdimigdi]

Just to clarify some things as to what the above that @[CPT]Crunch posted is:

 

Prepare for a blast from the past! VRdirectX.exe is the name of the profile, this stands for V-Rally (not Virtual Reality). The game had two executables, VRdirectX.exe and VRvoodoo.exe because it's from the late 90s early 2000s when there was still the transition between 3DFX's voodoo cards and going to (new at the time) DirectX-supporting GPUs. The settings in question are for "3D vision", a feature that didn't quite pass the test of time; back then you could buy special monitors you could look through shuttered glasses or opt to render a game in anaglyph mode (offset blue and red colors) and view the screen with glasses using blue/red lenses - games had to adjust various things in their rendering pipeline to get the 3d effect to play right, or gpu drivers had to help if they had a stake in this affair (like nvidia had as they were peddling 3d glasses back then [https://www.nvidia.com/content/newsletters/web/3D-Vision/3d-vision-glasses-web.html]) so due to (over)complications and not much actual added value the whole thing was eventually abandoned. Note that none of our current VR technology even existed at the time.

On the screenshot you sent, there are 5 parameters highlighted in green. These are the values you changed? All 5 of them? Or you are referring to one specific parameter?

 

Are you running also FSR mod?

 

I understand that this might be unintented benefit of an old abandoned functionality. But if it makes the game looks better with no side effect it is worth a try.

Also worth noting is that the last nvidia drivers to have support for this feature are these here:

Not supported as of, this is part of the code, but they have desactivated it and will not provide any support to it?

 

Or no longer part of the code, hence cannot be activated even through backdoor with newer driver?

[firdimigdi]

The latter. People still wanting to use 3D Vision must use driver ver 425.31 if it supports their GPU.

Thanks, so no point even trying if what is installed in the latest version of Nvidia drivers.

[firdimigdi]

It won't cause any damage if you did try and it's easy to revert; I'm just posting the facts I found when I wanted to know what it was that those profile settings did instead of just applying them blindly, what you want to do with that information is up to you.

 

Edited February 1, 2022 by Firdimigdi

[[CPT]Crunch]

The settings won't take if they're not there or invalid, there's something being switched if they can be changed and saved.  Interesting Firdimigdi, didn't know any of that, just assumed it was Virtual Reality.  Not much of a coincidence than having an enhanced 3D experience.   Blind luck.  If it hadn't been for a corruption in Win 11 and Il-2, I'd have never gone through such drastic messing with settings.  

 

Clean install of win 11 updated version and new game install, put these settings back in and bingo, and now with clean resolution and a sharp image it's magic.  I don't think it'll do much for a poor res with blurred image.

Yup, all five were set, I applied and saved them one at a time, if ever there's a setting that's invalid the app will refuse to save it.  There's a reset button in the controls to reset all your Nvidia setting back to default, so you can't really screw up if your starting from default.  Might want to save a profile if you have customized settings.  I started from a clean default.

But are you using the old nvidia driver or the newest one?

I have been successfully using Necksafer for about six months without any problems, but now it is not working.  At take off I will check that it is working , but then in the thick of a furball, I will try to look behind me and it will be missing, which is disconcerting.  When I close out of the sim, Necksafer is still open on my desktop, but I will find this message on my desktop:

 

 

When I click on Quit, Necksafer closes on the desktop.  Has anyone else experienced this?  Any suggestions on how to remedy?  Thank you in advance.

[Avetorro-VR]

I’m new to the game and I’ve been playing in VR for a couple of months now. The main issues I’ve come across is seeing targets from a distance ie high altitude bombing, due to having to turn off “distant buildings” in order to get vr to run smoothly when over towns/cities. Is there any way targets can be treated differently to all the other 3D buildings and are still visible when distant buildings is off ? Sometimes the target didn’t appear till I’m directly over it and it’s too late to drop bombs. 

[Waffen84]

Ive followed the guide for a vive pro 2 but im still getting great stutters at times in single player with a flight.  Ive got a 2080ti, vive pro 2 32gb ram i9 9900k.  not sure where else I can fix the stuttering.  Never got this in mission maker only in career.

There is a setting in the career called density. It controls how much ground activity is going on in the mission  If that is too high it will cause stuttering and may be why you don’t seeing in the mission maker. Just a thought but it might be worth checking.

I don’t know a way to treat targets differently than all 3d buildings. Maybe you can dial down some other things like presets, horizon distance and landscape detail. It may allow you to turn on distant buildings.

Just went down your path and had a flight over the Kuban.  You are right, noticeable difference in 3D Depth from the hangar to flying over the fields of the Kuban.  Trees now more varied in forests, forests pop move against terrain backdrop, hedges more prominent etc.

 

Will continue seeing how it looks on other maps and settings.

 

Interesting.

Thanks.

Non that I can tell.

 

I do demand a lot out of my RTX 2080 though and it struggles sometimes. 

Holding off for decent upgrade that doesn't require a house mortgage to pay for.  Maybe end of year.

[[CPT]Crunch]

Yeah, the Nevada deserts and mountains are simply fantastic as is downtown Vegas in DCS, like a free upgrade to your HMD.  Really helps the outside long distance stuff, but I suspect one needs a high res HMD with high end game settings to benefit.   

[Youtch]

I have tried this nvidia modified settings and unfortunately my experience was not positive, i don t know if it worked badly due to combination with other settings but for me although it made ground looking slightly better, this was also introducing a lot of ghosting on planes when dogfighting with high deflection pass-by, to a point where i could not stand it and reverted to initial configuration.

I m talking abour IL2 only, i have no clue for DCS
