Alright, I understand the reason for having NS reset my gamma before I play. The game should be dark and scary. Unfortunately, your definition of perfect gamma isn't even ATTAINABLE by my monitor, without changing my brightness settings in Windows.
I always knew setting my brightness up really high isn't fair, and I've always had mine set to a reasonable setting. Now, I can't see anything at all. You know the default HL menu, with the graphics behind the bright yellow text? I just see pure black back there when I don't have my settings changed.
I tried renaming the program that changes my gamma to something else, that worked. Finally I could see what the hell I was doing in the game. Too bad that upon exit, NS decides to change it back to default AGAIN. You're probably wondering why this matters if my gamma is set back to default when I quit a game. The problem is this: Now, every time I start a game, even if it's NOT NS, my gamma settings get changed NO MATTER WHAT. Basically this means that after playing NS even once, I need to reboot my entire computer to play any game.
If you're still wondering how dark my monitor is, even on the HIGHEST SETTINGS (100 contrast, 100 brightness): in the gamma setup tool, I can't even see the 4 below the one box (I can't distinguish any of the boxes from the background either), and I couldn't even see the CRATES the alien is supposedly hiding behind, let alone the alien ITSELF, let alone its eyes.
My only option right now to avoid this is to get a new monitor.
So far this is my only complaint (other than.... well you know). I've even spoken with Charlie in email a few times, he's a great guy (helped me figure out mouse-to-ray calculations for the little RTS mod I made).
For the next release, PLEASE disable brightness resetting, ESPECIALLY on closing the game.
