1. Yes Combat Arms needs a better Graphics card. My PC runs Warrock fine, but when i try to run Combat Arms..... Too Laggy.
2.FPS = Warrock ( Pro= Great Gameplay/Lots of guns(but a lot are F2P/Easy to level when PowerLvling | Cons = Too many hackers/Others Lag
RPG = Maplestory ( Pro= Challenging/ Great Community/Lots of people play/ No hackers/ No lag | Cons= Gets repetitive/ Over powered classes
RTS = Starcraft 2 Brood Wars ( Pro= No Lag/ If you like RTS, this is perfect Cons= You have to buy C/D if you get cracked not too many people online in that server.
Press Thanks If I helped :P
