VR experiences IL-2 Korea

[Gunfreak]

I assume if my monitor don't support HDR, I don't need to turn it off? Even with my pimax running, I have no ability to do anything with HDR in windows.

[Blooddawn1942]

Why is everybody complaining about the head movement restriction? You can simply turn it off in the settings. 

[Jade_Monkey]

The Indirect Lighting setting in the Graphics menu seems to be a massive resource hog in VR. I'd recommend turning it off if you have it on.

 

Still have not found very satisfying settings, but @ronht posted a good starting point on the previos page for those using Pimax Play.

On VR preset with everything on Normal/Medium and FXAA x4 in VR I get around 70-90 FPS

[Senor_Jefe]

Sounds like the baseline isn't to go with the "VR Optimized" preset and make adjustments, but go medium first?  Also surprised users are reporting FXAA/MSAA with 2-4x is working better than DLSS.  I have a feeling DLSS preset M/L have something to do with it.  Really wish devs of all sorts of games would make it easier to change presets.  Would really love to try preset K, yet it's like pulling teeth.

@Sneaksie why Joy2Key do not work in Korea? The new key bindings are great, but I miss my combos (i.e. to fast write check 6 in team chat, or lowest zoom toggle for strafing).

Have you tried FSR upscaling in VR? I would go with FSR, AA off of course, Open XR API, toolkit off, native HMD resolution, .....

Upscaling like DLSS, for example, should only be an option for... weak computers for VR, like 3080 cards, e.g., and not for the RTX4080, 4090, 5070Ti, 5080, 5090 series.

Proposing this as a standard for VR is a mistake. DLSS isn't a holy grail and causes artifacts, blurs the image, and adds ghosting, which looks very bad in dogfights (phoenix streak). If we're talking about top-of-the-line graphics cards and come up with the suggestion, "Turn on DLSS," something's wrong. We're not talking about a civilian simulator, where you can actually fly with DLSS because you don't need that much dynamic range, but a combat simulator.

The image must be smooth during dogfights, attacking targets, and explosions, and above all, sharp from many kilometers away (DLSS, for example, causes distant objects to appear blurry). This isn't the way to go.

The game clearly hasn't been optimized for VR, and now you have a pretty big job to do between now and August, before the release date. I hope 1CGS will go full force and we'll get what IL-2 Korea will be like for years to come in August.

I'm delighted with the simulator after my first experience, but I'd appreciate some support with VR. The main problem is the cities, which cause a 50% drop in FPS in VR. I think it's a LOD issue, a lack of optimization, and perhaps some things are too detailed, which is why they overload the PC. DCS has much more complex cities (e.g., London, and... LOL, I get 72 FPS there, max, about me at 72Hz, stable, here over a larger village I get... 40 FPS. Apart from the cities, everything is fine for me. So something's not right here.

I also requested a separate thread for VR bugs. Where should we report these? The 2D and VR threads should be separated, as they are separate issues. Please create a thread for VR here, as I can't report bugs. Thanks in advance!

VR for me is a mixed bag as well, very fluid at times, but then not so much at other times.  I am convinced that this is a settings issue, and I just have to figure them all out.  I've grown very accustom to the crisp details a 5090 / 4k OLED screen will provide in Great Battles at a constant 72 frames, however with the new title, at times, this looks like a blurry mess.  Need some good diagnostic tools and maybe a nice "do this dummy" video.  🤣

And yes the game scale doesn't feel right. I think you can alter that with OpenXRtoolkit.

Yes, that's right. However, there's a bug because IPD + and - don't work here. They don't do anything, so it's a serious problem. We have the Lego Man effect because of this.

[Traffic]

I've found the smoothest settings for VR is by turning off AA, DLSS, FSR, basically everything. I have the game set on ultra with no upscaling of any kind and its quite smooth, crisp textures and relatively stable fps. So Im not sure the upscaling is fully functioning and I see no visual difference in clarity of any kind. No jagged edges, nothing.

On many MP servers this is forced on, so people can't cheat by being able to look around in ways that a real pilot couldn't.

I'm finding this setting doesn't even work, in sp or mp.

There is now a topic to report VR issues:

Blurry Terrain is right,, VR here too. Gives a headache after a bit...

Great! Thank you @LukeFF ❤️

Been tearing my hair out but finally got to what I find is acceptable in the FPS department whiles still maintaining decent graphics. Thought i'd post for those with higher end systems if anyone wants to test it out. 

Specs: 

Graphics: 5090, CPU: 14900k, 64 GB DDR5, M.2. Highspeed SSD. 

Heaset: Pimax Cystal Super, Micro-Oled. 

Used OpenXR, I could not get OpenVR to work nice, and I hate launching steamVR and having settings in two different places. 

Pimaxplay settings, Set Headset resolution to .80 *Would be nice if IL2 would implement Dynamic foveated rendering, someone said that they chose not to do it because they only saw 10% performance improvement with it(Someone said on reddit that is what the devs said) That 10% would be a HUGE help for those right on the edge that have eyetracking. And with steams new headset being able to do it, why not. It sure does make a difference for me in DCS.

For Meta users, it's worth setting the FOV in the Debug tool (I have a script for this myself). This saves a lot of performance. It allows me to achieve stable 72 frames at 72 Hz (of course, not over cities like Seoul) with reprojection off. For me, a FOV of 0.75 doesn't affect my field of view.

Sounds like Deferred vs forward rendering has something to do with it:

Will native foveated rendering be implemented to improve VR performance?

We have already investigated foveated rendering and conducted a number of tests. In our current DX12 deferred rendering pipeline it shows only a very small performance benefit (less than 10%), which is not significant enough to justify implementation.
In forward rendering it can provide noticeable gains, but that is not the approach we use, as deferred rendering allows us to support the full range of graphical features in the project.
We continue to research and prototype such technologies, but we only implement features that provide a real, measurable benefit to the user experience.

You can now change the preset per-game right in the "Nvidia app".  For the "newest recommended" setting K is alread the default for "Balanced" (58% res scale) and above.  If you play multiple titles w/DLSS you have almost certainly experienced it already.  It is lighter than M and L (especially for those not on 4000 or 5000-series) but the improved motion handling (less ghosting, smearing, etc.) is WELL worth the slight overhead IMO, and the overall improvement in image reconstruction/clarity means I can normally drop a full scaling level over preset K without losing fidelity.

Edit: People really need to be sharing if they are getting CPU or GPU-limited when experiencing poor performance, I would imagine the new physics modeling is one of the more performance intensive changes in Korea's engine vs BoX.

Sorry to buck the trend, but I’m getting a solid 60fps with everything maxed out and no upscaling. It looks gorgeous too. 
Pimax Crystal Light running on Pimax Evo. 
RTX 5090, Ryzen 9950X3D, 64Gb RAM. I’m wondering whether VRAM is the issue for most people?

[Galraak]

Honestly, VR performance is just shameful... 
With my 5090, my 7800X3D and my 64GB of RAM, I have big drops in FPS when flying over cities, and it just becomes unplayable in the mission with the B29s. 
How can they say that the quadview will bring nothing? I'm barely on average setting...
Who will want to play a game with so little FPS in VR? I do not understand...

[plucka99]

Reverb G2 users:  Im having issues with brightness/gamma to the point where everything looks very overexposed and super bright.  The clouds are so bright I cant see my reticle, the runways looks like snow.  Its like HDR is turned on or contrast is maxed out.   GB was similar although not near as bad.  Windows and in game HDR is turned off, tried setting gamma in game to minimum and didn't help much.  Cant see anyway to adjust brightness/contrast in steamvr.

[Syphen]

I can fly free missions with playable framerate on my Reverb G2 with 12700k and 3080ti, all normal settings. Once I try the B29 intercept, it becomes a slide show.   I miss the performance I got in great battles. 

[Jade_Monkey]

This one might not be a VR exclusive issue, but for those (being forced to) using low graphical settings, is this how nights look for you?

You probably haven't been over Seoul at low pass, LOL. 😂

At night, there's simply no lighting (from sky), which should be visible from the moon, no light reflections on the clouds either; it doesn't look as pitch-black if we are talking about realism. Furthermore, city lights are rendered only in one eye.
