Ok, thanks ! if you see  a better difference  ,i will try again according to your settings ...

[General] FPSLimit = -1                        // Caps the frame rate. 0 is uncapped, -1 sits just under the refresh rate. [Graphics] DisplayMode = 0                      // 0 exclusive fullscreen, 1 borderless at the desktop resolution, 2 windowed. VSync = 1                            // Waits for the next frame refresh before presenting. Prevents tearing, but adds up to one frame of latency. AnisotropicFiltering = 16            // Forces anisotropic texture filtering. 0 or 1 is off, up to 16. MSAA = 1                             // Forces multisample antialiasing. 0 or 1 is off, up to 8 samples. SMAA = 1                             // Enables subpixel morphological antialiasing to smooth jagged edges. [HUD] ScaleHUD = 1                         // Forces HUD and Command Map scaling on, overriding the in-game setting. OpticMaskAspect = 2                  // Controls the aspect ratio of scopes, binoculars, and night vision. 0 stretches, 1 preserves 4:3 with black bars, 2 fills the screen width. [Input] LookSensitivity = 1.0                // Multiplier on top of the in-game mouse sensitivity slider. CursorSensitivity = 1.0              // Multiplier on top of the menu, pause and command map cursor speed.   My settings in EnhancedGR.ini

You have three options in the tool—try the third one and set it a little lower in the game. I tried it, and it works, but I can't really compare it since I only have a 1920x1080 resolution.

Yes, same resolution in game and desktop : 2560x1140 but ,the screen interface with the tool is 4/3 in place of 16/10 fullscreen . Are you going to try the tool ?

The windows in the middle look good; only the ones at the bottom left and right are a little small. Do you use the same resolution in the game as you do on your desktop?
