After get lots of i just decided to make this old bug public.

What i am talking about is the old gammabug

i know this isnt anything new and undiscovered but you can say the same about cooking tutorials.

anyway, some of you might have gotten this bug accidentally before. and it wasnt anything that special.

But if you abuse this propperly, it can result in really bright (or black) opponents

here some examples of what each gamma value can look like

You can also exploit this bug in the complete opposite way which will result in this:

you can do this by filling in a low gamma of 0.1 at the second step

and filling in high gamma of 3 after the vidrestart (before changing map)

edit: I didn't start to use those settings though, since I don't think it's an advantage. It's only great for far range shooting, enemies become _really_ bright.

I first backuped my old configs, then removed all the .cfg files with graphic settings I had in etpro folders. Then I played a demo and did /cvar_restart , then /exec gammabug.cfg and then /vid_restart. After that 1 vid_restart I didn't have to do anything, now when I connect servers I have that bug working.

So you can't do even one vid_restart (when replaying a demo for example), if that would be the only one required?

remember to change r_displayrefresh, I have a TFT and that's why I use 75.

I can /vid_restart no problem, I can alt-enter no problem, and my UAC is turned on. I run ET as user (not adminstrator) and I can't understand why it wouldn't work on others.
