Would it be considered cheating if i changed the textures of the ct and the t's head so they are easier to see? I know this seems dumb but, is it cheating?
iirc yes, official valve servers don't like any sort of modifications to the game and may issue a VAC. although I'm sure its not generally considered "cheating"
try upping the digital vibrance of your monitor / graphics card if you want to see things more, apparently what the pros do. I don't personally change the digital vibrancy because it looks forgety when doing anything else
