VR experiences IL-2 Korea

[GiftGruen]

Mhmmm. No, I don‘t think this is true.

QVFR is a tool to support GPUs to achieve sufficient framerates. Like all FoV techniques do. That’s all. It doesnt change the VR experience in general.

What is the key mapping name to use zoom in VR?

I’ve searched through the key mapping options but I cannot find it.

It's under Cockpit View in keymapping settings, lines starting "Zoom Cockpit View: Level 1"

Etc.

That's my point. QVFR gives a significant performance boost.

It increases CPU load (4 images to compute instead of 2) and decreases GPU load (less pixel to compute). So it depends...

Yes, there are elements which depend on specific pc builds and QVFR settings. My personal experience from other flight Sims is that I can get a very big performance boost. I would have liked to have seen this available in IL-2 Korea. 

Quest Pro; RTX5080; 9800x3d.

First and foremost, the IL-2 Korea itself requires optimization. The product has been released unfinished (EA = WiP for sure), and while it's mostly fine in 2D, we're all complaining about performance in VR, and we're not even talking about high settings. Even graphics cards like the 5080 and 5090 can't handle it, and they can't only maintain a stable frame rate, sometimes dropping to half or even less (e.g., when flying low over cities) - so something is seriously wrong. I have stable 72 FPS over the whole WWII London in DCS than here over a medium - sized village here is a problem. Also in MSFS2024 I can fly on high settings over cities and it's ok, usually in MSFS it also has constant FPS. The potential is there, and if 1CGS can perfect it, it will be a great sim and certainly a step forward. However, it requires the full team's work and a thorough analysis of the content of VR users.

I hope this month they will be spent not only working on content like career and missions, but above all on reported bugs and technical improvements. Without them, the simulator won't be up to date. I can't even imagine flying in multiplayer in VR (like in the IL-2 Combat Box server), when someone to fly over the city in 2D, and I can ... go home without doing anything. The game must perform equally well in 2D and VR without any noticeable performance drops. If Seoul City is generating 60-90 FPS in 2D, that's a bug, because in 2D it should generate around 150 FPS or more to be fine in VR and have some headroom.

I believe this will happen, because, for example, DCS has much more detailed cities, up to 5x larger than Seoul here, and yet I don't have any FPS issues there. Modern Las Vegas, London, Paris, Cairo, Gaza, etc., generate a constant 72 frames for me. So it can be done (I would like to add that Im of course talking about the situation without DLSS enabled, which is not a solution for top GPUs).

2D. At higher altitudes, my FPS is very high, often reaching 200+. However, when I'm sitting in the cockpit on the airfield with nearby objects and other players' aircraft around, it drops to around 100 FPS or even lower. If I zoom in on another parked player's aircraft, it can drop as low as 50 FPS.

The FPS fluctuations are huge. It seems like something is putting an excessive load on the system.

Up high it's all GPU. Closer to the ground CPU usage increases significantly bottlenecking the GPU. I think that is one of the key aspects they need to optimize, the other one probably being the openXR implementation.

Yes it's CPU, but what ? I do understand why  with huge bombers formation in single player mission frams are dropping significantly but the same bombers formation in multiplayer is smooth without significant fps lost. In first simulation is run on local computer later not.

Don't know enough, not my area of expertise.

If I were to guess, it's the handling of many detailed objects that stop being rendered once you are high enough. Also grass, terrain roughness, etc? I don't think CPU= simulation only.

Thanks ‼️ This could be some kind of OpenXR Toolkit replacement. It's a shame it's the only one without a World Scale option. I'm still waiting for the patches that will fix IPD in IL-2 Korea.

Have you tried this yet?

Has QVFR, head rotation and scaling.

Personally, I need two options: CAS - sharpness and World Scale. This Vector doesn't support both.

For my Pimax Dream (with 4090) I tried using the Sboys3 driver through Pimax Evo. It works now.

This tricks SteamVR into thinking I'm using an actual Steam headset and now I can use the smoothing feature SteamVR has. This allows me to have a very playable experience even with 30-40 fps. I shot down 3 sabres in two sorties! 

I don't understand how a random dude on the internet can create a driver that allows this and all other VR companies can't, but I'm happy. The game is playable and enjoyable even with crap fps.

Just confirming that I'm not crazy, VR does not support the guncam view with the old grainy film filter, correct? It seems like that's only for flatscreen?

[YoYo]

By the way, there's a map of the theater of operations in the Museum that looks pretty cool in VR. It feels like I'm about to play Total War: Korea. 

[Husar]

I asked man who opinion I trust about DFR and about dev team not pursuing DFR because internal test showed only 10% gain in VR.

[Dash,Polder]

For Pimax owners they're working on an all new smoothing algorithm, the current one is sort of broken.  This round with Korea I'm forced into using it to get acceptable visuals, and in it's current state smoothing isn't half bad so long as I stick to the jets, it's almost like flying under turbulent water behind a prop though.  If they can get smoothing to a much better state there is hope yet for us Pimax users.  This sim starts to look really good in VR when you can ramp up the settings near max.

[wuVR]

Sadly, only in near max or max-settings does the Game look good, aside from the lighting, which is astonishingly beautiful made.
But good (sad) to know, my crosseye&performance-issues are not on my end only.
Compared to Great Battles, Korea runs like $#!7 in VR.
I tried all the tools & tricks i gathered in 8 Years of VR, to some avail, but still, VR is painfull right now.

The Thing is, it´s a fkn great Game allready,  tho´.. i just can´t get back to flat 2D Pancake-mode.

We have also fixed the issue of "jumping" trees. Many players have reported that certain trees behave strangely, periodically jumping and sinking into the ground. This has particularly affected low-altitude flight experiences over the beautiful Korean landscape. We have identified and resolved the underlying causes of this issue, and this change will be included in an upcoming patch. As a result, players will soon be able to fully enjoy the thrill of flying over river mouths.

Looks like they fix it?

(different rendering for right and left eyes)

[wuVR]

We just want the Game, to render 2 different Perspectives of the same Picture
Not 2 different Pictures
same goes for lights and LoD

Trees jump in 2D also. I also noticed trees shadow jumping around. Those break this buitful landscape, when there is no issue with blurred textures 😅

[FuriousMeow]

The biggest impact to on-ground/airfield FPS is the grass. I shorted from ultra to whatever was the next option down and gained about 20fps. I turned it off and FPS doubled on the runway to inflight FPS.

They are working on a faster implementation currently, so hopefully that will improve things.
