I put together the NVIDIA Control Panel settings that work best for my setup: RTX 5070 Ti + ASUS VG27AQM1A (2560x1440, 270Hz, G-Sync Compatible) + Skyrim SE with NAT-ENB.

NVIDIA Control Panel settings

1) Display → Set up G-Sync

Open NVIDIA Control Panel → Display → Set up G-Sync and use:

• Enable G-Sync, G-Sync Compatible: On

• Enable for windowed and full screen mode: Selected

Since the VG27AQM1A is G-Sync Compatible, this is the correct choice for Skyrim running in borderless windowed mode. NVIDIA’s own help page says to choose either fullscreen or windowed + fullscreen depending on the type of app you run, and borderless Skyrim benefits from the windowed option.

2) Display → Change Resolution

Open NVIDIA Control Panel → Display → Change Resolution and set:

• Resolution: 2560 × 1440

• Refresh rate: 270 Hz

• Output color depth: Highest (32-bit)

• Output color format: RGB

• Output dynamic range: Full

The important part here is Output Dynamic Range = Full. If it is left at Limited, blacks look lifted and ENB colors can look washed out.

Program settings for Skyrim SE

Go to Manage 3D Settings → Program Settings → SkyrimSE.exe and set:

• Anti-Aliasing – FXAA: Off

• Anti-Aliasing – Gamma correction: Off

• Anti-Aliasing – Mode: Off

• Anti-Aliasing – Setting: Application-controlled

• Anti-Aliasing – Transparency: Off

• Anisotropic Filtering: 16x

• Texture Filtering – Quality: High Quality

• Texture Filtering – Trilinear optimization: Off

• Threaded Optimization: On

• Vertical Sync: Off

• Low Latency Mode: Ultra

• Power Management Mode: Prefer Maximum Performance

• Triple Buffering: Off

• Max Frame Rate: Off

This keeps the driver out of the way and lets ENB handle the image. Disabling driver AA avoids conflict with ENB, while anisotropic filtering at 16x is a simple visual upgrade with almost no downside.

Frame cap

Since I’m using NAT-ENB, I set the frame cap in enblocal.ini instead of the NVIDIA driver:

[ENGINE] EnableFPSLimit=true FPSLimit=269.0

Capping 1 FPS below the monitor’s refresh rate is standard G-Sync practice, because it helps keep the game inside the variable refresh range and avoids hitting the ceiling.

What to leave alone

I do not change global NVIDIA settings for this. Everything is set under Program Settings for SkyrimSE.exe only, so other games are unaffected. That keeps the profile clean and avoids side effects in other titles.

NGVO / MO2 note

Because I’m running NGVO through MO2, the INI files in

Documents\My Games\Skyrim Special Edition\

are not the ones the game reads when launched through MO2. MO2 uses profile-specific INIs instead.

Those are located in:

C:\Modlists\NGVO\profiles\<your profile name>\

Inside that folder you’ll find:

• Skyrim.ini

• SkyrimPrefs.ini

My enblocal.ini is in:

C:\Modlists\NGVO\mods\Cabbage ENB\Root
