Adjusting Gamma in (Borderless) Windowed mode - FLHDE/freelancer-hd-edition GitHub Wiki

It is known that (Borderless) Windowed mode causes the Gamma slider from the options menu to now longer work. In this case, the only known way of adjusting the Gamma is to do it via ReShade's Tonemap shader. This tutorial explains how it works. N.B. This only works if ReShade has been enabled in the installer options.

1. Launch the game.
2. Press the 'Home' key.
3. Make sure you've completed ReShade's short tutorial.
4. In the ReShade menu, ensure Tonemap [Tonemap.fx] is checked.
5. At the bottom of the ReShade menu, you should see a Gamma slider.
6. Adjust it to your liking.
