im jus tryin to ply gem…
This MUST be a joke. Like - “Hmm increase the gamma. If that doesn’t help, change your monitor. If you STILL WANT better brightness, maybe like - uhmmmm modify the games glsl fragment shader to render the image to the screen?.. yeah, do that.”
There is no way this is meant seriously… but if it is, i do enjoy that…
Try applying the Adobe RGB colour profile to your screen. It might help in scenarios like this.
But yeah I’m not familiar with the game. But it sounds like they gotta refactor their drawing routines to be adjustable.
