I am attempting to play Team Fortress 2 on my computer, and I have a relatively slow computer. Whenever I try to play the game with DirectX 8.1 or below I get this error: The instruction at "0x127e5b84" referenced memory at "0x21596d24". The memory could not be read. Click on OK to terminate the program. This does not happen when I use DirectX 9 but the game runs too slowly when I use DirectX 9. Anyone have any idea what the problem is?
