Video and Sound Settings

It's not exactly a bug, but the flickering effect is really unpleasant; it's very hard on the eyes and feels unnatural.

I don't know why my Il2 Korea has inactive upscaling option in the settings menu. It is greyed out. Any other game works ok with dlss on my computer. I play OpenXR with quest 3. What can I do to set this option to dlss?

Upon launching the game, all graphics settings are reset to default/benchmark settings.

I had this too. Starting the launcher in admin mode seems to have solved that issue for me.

Found out something by enabling the registry tweak to display the DLSS model. It defaults to transformer v2 model (DLSS 4) - model preset M. While this model provides a lot of quality upscaling from low resolutions, it is also VERY heavy on anything but the latest RTX 5x class cards. This explains why DLSS provides a lot of image quality but less than expected performance improvements.

Fortunately it should be relatively easy to use something like nvidia profile inspector revamped to switch to profile K/J or something older (CNN) even.

I just tried it out going from profile M -> K.

5120x2160 DLSS Quality (default) Model M: 57fps

5120x2160 DLSS Quality (default) Model K: 65fps

It would be nice for there to be an ingame option to be able to switch DLSS models: CNN, Transformer 1, Transformer 2.

I think the upscaling might just be for flat 2d monitors... I guess this is replaced by the 'VR Resolution Factor' but it doesn't say whether any upscaling tech is used for this (such as DLSS or FSR).

After installing the latest Nvidia driver, I was able to enable DLSS in the game.

Definitely needs an option to toggle between versions. Or just a config file to point the game towards which version you want.

Running the L and M presets on a 3000 tier GPU is really best avoided.

Can you provide instructions on how to most easily make this switch?  I'm having a heck of a time using DLSS Swapper to try to get it done (just isn't working for me), and of course IL2 has never been supported in the Nvidia app to do it there.

[Donik]

Why aren't you guys just using the NVIDIA app? It seems to be supported just fine if you manually add the EXE.

Have you confirmed in-game that it's actually using your preset?

[Donik]

I couldn't get the NVIDIA overlay to acknowledge what model was being used. Confirmed via DLSS Swapper on screen indicator it was using M. =/

Was able to force L with DLSS Swapper at least.

I'm not sure if this is common knowledge, but my installation on a DELL G16 gaming laptop defaulted to using the low-power Intel graphics chip when I started the game. The mouse was choppy and the game unplayable. I checked Task Manager and saw that the RTX4070 wasn't being used, so I went into Settings > Gaming > Game Mode > Graphics. There I added the IL2 game EXE file name (check task manager to be sure which EXE is running with the game) and then set it to always use your gaming video card. This is probably only an issue on gaming laptops with dual video cards. Now it's time to learn to fly this thing.

I was able to use DLSS tweaks to switch to preset J. But the games anti-cheat flags DLSStweaks so you can't use it while flying on any MP server that has anticheat enabled.

Will try using DLSS swapper instead.

dear developers team,

Can you please recommend what should I change in graphics settings to avoid flickering?? I'm experiencing constant flickering regardless of DLSS enabled or not. I've tried to switch off HDR, but it didn't fix the problem.

PC config: RTX5080, 64Gb RAM, Samsung Odyssey G5 monitor (G-sync enabled). Latest nvidia driver is installed.

Below is my graphics settings, and the short video of this 'flickering'

Turning off Indirect Lighting added enough FPS that I could upgrade from DLSS Quality to DLAA rendering and still max out my monitor's refresh rate.

[Redeye]

I am having blurry gauges in cockpit when using DLSS on quality. I have a I7 7700K CPU and RTX4070Ti Super. This is even with 4K textures. Right now I have set the game to DLAA with 2k textures which gives a much clearer image in my Quest3.

Hey this was good advice, I got quite a performance jump by turning this off! I wonder if it needs some more optimizing? Running an AMD 7900XTX

1. На повторе у МиГ-15бис и F-80C-10 (возможно, и у остальных реактивных истребителей тоже) в кабине и с внешнего вида звук двигателя повышается/понижается в зависимости от увеличения/уменьшения оборотов только до определенной отметки (что-то около 300-400 оборотов) и после этого остается на той же высоте. У поршневого Як-9П, например, на повторе такой проблемы нет, звук двигателя в зависимости от увеличения/уменьшения оборотов проигрывается правильно. 

2. У ряда самолетов (Як-9П, Ла-11) с бортовых камер (команда Выбранный объект: бортовая камера) звук очень тихий, гораздо тише чем с других внешних видов.

3. У Ла-11 очень тихий звук удара колес шасси об ВПП на взлете и посадке, по сравнению с другими самолетами.

Since Patch 03:

Mig15 Sounds for Flaps, Gear and AirBrakes are dimmed out to almost zero, even if sound in settings is set to 100%.

Motor, Weapons work fine / seem unchanged to Patch 02, so it's not all effects.

Don't know for other plane types, just tested Mig15 yesterday.

Hello, I have bought the game on steam yesterday, Game runs (but stutters) when playing with 4k textures, so I wanted to lower the textures but when I toggle off the 4k Textures option and restart the game I receive: 

DXRenderer11::endFrame(..)
DXGI_ERROR_DEVICE_REMOVED (0x887a0005)

And game locks up, it doesn't close. If I close the error message it gives it again immediately.

Nvidia GTX 1650, Up to date drivers, I tried verifying files on steam, clearing Nvidia Shader Cache, Disabled Nvidia Overlay and no changes.

You could not have bought the game on Steam, as it's not released there yet. Do you mean Great Battles?

Hey there, Yes, the report isn't about IL-2 Korea, its for Il-2 Sturmovik: Battle Of Stalingrad. It seems I posted it on the wrong section, apologies, I'll repost the question there these can be deleted (I don't know if I can delete them, I don't see an option to.

I think the resolution you've chosen is too low? DLSS/FSR works if you have a higher resolution set, I think, since it renders at lower resolution and then upscales to the set one.

Try setting a 1440p resolution and see if it works.
