The only way to achieve a 512MB video card at the moment is to connect two 6800's together, I am not doubting your quotes, but I do not experience any type of lag. Or notice a switching of the textures. They very well may be switching textues, but it is so damn dark you can't even tell. Like I said before, to each is own. Play it, love it , I don't care, Doom 3 is just keeping me busy until the real innovative (maybe not graphics wise) good games come out...Half Life 2. Oh yeah and Halo 2. Ahh Halo 2 a perfect example of game that will be awesome and won't choke anyones system in the process. An awesome game because of gameplay and story, not just eye candy.
I think we can all agree that we cannot expect anything different in Doom 3. It is what it is... Doom on serious steroids. Same gameplay as 12 years ago, same guns as 12 years ago same premise as 12 years ago, Run shoot Run, don't think, kill, kill, kill. That's it. It was my mistake to expect anything different. Personally as a gamer now a days, I expect more stimulation. Doom was great and innovative years ago, now ehhhhh, I have experieced and now demand more. Let's be clear I'm talken' gameplay here. I like games that make me have to scheme and plan in order to survive or at least have a purpose. Running down corridors and shooting into darkness, just doesn't do it for me anymore.
PEACE!
PS..Where's the scotch tape button. I'm tired of holding the damn flashlight
