First off I'd like to say I've been playing this game since beta on my current rig. From the begining the game had bad problems with utilizing multi-cores, and nvidia cards had HUGE memory leak problems. I've watched this game come from nearly unplayable graphics wise to a beautiful work of art. I've personally tried every video configuration that my system can offer. With all that I figured out how to play this game with every single setting maxed out on my system (it does utilize CPU, Ram, GPU more than any MMO). I mean with bloom enabled, 16xQQ AA/AF, 1680x1050 resolution, and all effects and draw distances as high as they can go. I usually get on average 50 FPS on any land outside a major city. Inside the major cities I get 15-30 FPS depending on how many NPCs and other players I have to render. In instances and "night quests" where you only play with yourself and NPCs I get no less than 60 and up to 100 FPS. The only PvP I have done is the matchmaking type and not the huge open battles as I've only gotten up to level 31 so far, and during that I average 30-45 FPS. The only way I can get any performance that is playable at these settings is to use system RAM. The game will only allow you to use as much possible for graphics with out interfering with the OS and the client. For 2 gbs, I am able to use 144mbs of system RAM. So with that being said, for those of you with lower end cards who want to upgrade just a little to play this game, my advice is to get more RAM if you already don't have 4gbs or more. If you don't mind the small difference the AA/Bloom makes then your good to run those at lower settings.
