Spring RTS Engine

yea my laptop and other desktop run the game just fine and are pretty new. this is just my old junker i was trying ot let my brother to use.

and these cards will be compatabol with my mother board?

How much would it cost to get a card that will work? like the cheapest one compatabol with my comp and the game.

i dont think my graphics card is good enuff. can any one tell me if it is i have NVIDIA RIVA TNT2 Model 64?

I know there was a thread on this topic but it was of no help. When i try to play a game the fallowing error comes up. update drivers. extension_ARB_env_combine.

My ? is where do i go to update this driver?
