Hi. I am a new person here. I played some TDM a year ago, on my old computer. TDM was good when it started, but it's better now, and there are many more fan missions now. I am delighted to be back. I am now playing on a Nvidia GTX 580 with 1.5GB vram. Already, 2 FM's have used all 1.5GB vram: Fiasco at Fauchard Street and Return to the City V2. From my experiences in directX games, when all vram is used, fps will greatly decrease and the game will be very laggy. I am absolutely shocked that in 2FM's, all vram is used and fps is a constant smooth 60fps. How is this possible? Is it normal in openGL games that fps will not decrease even if there is too little vram? Or does doom3 have special vram handling? Did TDM coders make special code to handle vram? Seriously, I wish all PC games could handle vram as effectively as TDM does. It's very satisfying to use all vram without any negative effects.
