Uhh yeah, you tagged yourself as a cheater there pal. You specifically wanted to get ATI so you could see the shadows through the walls, and inadvertant EXPLOIT whether you seem to think so or not. Exploit = Taking advantage of a flaw, which you are clearly doing
You are getting peoples locations based on seeing their shadow through walls...THAT IS AN EXPLOIT, when you have an unfair advantage and specifically because you say "Well Id rather get ATI so I can do it" so obviously you're saying you can't play as well without that little bit of help.
The MSN wallhack thing is rather old and said this, it was previous drivers and I don't even know what driver or specific card.
This proves ATI has inferior cards to some degree if it causes such BS in games.
I don't know what your conception of an exploit is, but anything that gives you an edge over the other player, IS AN EXPLOIT, ESPECIALLY since you said yourself you'd rather have ATI specifically for that reason.....soo yeah think what you will, but that's cheating. It may not be a blatent wall hack, aimbot, multihack or anything like that, but you are depending on specific piece of hardware for seeing shadows through walls...that's just ridiculous.
If you have skill in the game, then 'Seeing shadows through walls' shouldn't even be weight into your decision based on buying a card. The performance that the card gives you should influence your decision, not so you can get peoples locations because of a design flaw of ATI's cards.
and saying I need to get skill because I bought an ati card is way out of line
I said if you HAVE to use that exploit, then you need to up your skill. If you have skill, then you shouldn't need to rely on that exploit and have it effect your decision on buying a card purely because it has that flaw
