The GTA mod sounds awesome, I'll have to reinstall it, but I just recall it being fuzzy and.. blobby, it also played pretty rough, but I'll give it another go for sure.
The graphics are beautiful. We ARE talking about ARMA2 right? Because the graphics are gorgeous for real. Not fuzzy or blocky. There are some lighting issues, but overall the game is worth its weight in gold to me. It is one of a kind and it really shows that.
