Hi all! Hopefully someone can help me, I am going completely mad. I recently bought a GF4 4200Ti 128 MB to replace my old Radeon 9200SE, but after installing the new card and then installing new drivers (nVIDIA forceware 220.127.116.11) I can't play any new games (eg. Doom 3, Half-Life 2, Quake 4) with the exception of Star Wars: Battlefront 2. The games run fine when initializing menus, etc, but as soon as the card starts rendering I get 0 fps and Half-Life 2 just crashes. My sys is an AMD 2800+, K7 Triton, 512 MB and GF4 4200Ti 128 MB AGP 8x. Please, someone put me out of my misery!
