Brightness/Gamma issue

[apchistuo]

I tried to increase the gamma in scp cb because it's so dark, but instead it brightness the whole screen instead of the 3D rendering space, i found an old fix from 2015, but it doesn't seem to work now.

Hello apchistuo,

the reason it doesn't work is because first, the Blitz3D gamma only works with the fullscreen mode (no windowed or borderless). Second, this feature broke with Windows 8 and above. Blitz3D is an outdated engine from 2001 running on DirectX 7.
