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…
