How I got rid of shimmering in GB

[Hauggy]

Keep in mind I have a 5060Ti and a 1920x1080 (Flat Screen)

STEP 1: IN-GAME GRAPHICS SETTINGS

Landscape Filter: Set to "Normal" (Avoid "Sharpen" as it causes ground crawl).
Antialiasing: Set to "4x" (Matches the configuration file below).
HDR: Set to "OFF" (High contrast heavily increases edge shimmering).

[STEP 2: NVIDIA CONTROL PANEL SETTINGS]

Open NVIDIA Control Panel -> Manage 3D Settings -> Program Settings.
Add "IL-2 Sturmovik" (IL-2.exe) and change the following lines:
Antialiasing - Mode: "Enhance the application setting" (This allows NVIDIA's transparency supersampling to work alongside the game's native MSAA).
Antialiasing - Transparency: "4x (Supersample)" or "8x (Supersample)".
Anisotropic Filtering: "16x".
Texture Filtering - Quality: "High Quality".

[STEP 3: NVIDIA DSR (CRUCIAL FOR 1080p SCREENS)]
Running the game at a higher internal resolution is the single most effective weapon against aliasing.

In NVIDIA Control Panel (Global Settings), find "DSR - Factors".
Check "2.25x DL" (Deep Learning Dynamic Super Resolution - DLDSR). This scales a 1920x1080 display cleanly up to 2880 x 1620 using AI downscaling.
Apply the changes.

[STEP 4: STARTUP.CFG EDIT]
Because the in-game menus can sometimes bug out or fail to apply anti-aliasing properly, you must force it via the configuration file.

File Path: Steam\steamapps\common\IL-2 Sturmovik Great Battles\data\startup.cfg
Open the file with Notepad, find the [graphics] section, and change it as explained :

You might try sparse grid supersampling in Nvidia profile inspector. That may solve this. I am not in front of my PC at this time but if you try profile inspector for IL2 Battle of Stalingrad you might see a benefit.

I got rid of it by ticking "Sharpen" option and then putting landscape filter to "Blurred". Max settings excluding clouds and shadow qualities, HDR on.

Tried before, never worked with some others settings on and it actually got worse

 sparse grid supersampling was only method to get rid of shimmering in ROF but it works with ROF DX9, I belive SGSS dosent work with DX10/DX11/DX12 games
