Guys Please, Check the system requirements. It says everything clearly.
1) All the people with Intel(extreme) Graphics etc. Chips won't be able to run the game.
2)Only ATI and NVidia Chips(if Integrated) and graphic cards(AGP) are supported.
3)All Sound Chips that run well with DirectX 9c are supported, even if its Sound Max or anything. (Has to be able to run with DirectX 9c)
4)And to get good FPS(frames per second), at least 30fps, u will need a P4 1.5-1.8 GHZ or Athlon 1800+, with a 128 MB graphics card. This is a must.
5) Those 64 MB graphic cards(mx200, mx400, mx420, mx440), even fx 5200 128MB won't do the job. This time some money on graphic cards has to be spent. That's the harsh truth. The gaming industry has evolved. Do something for the love of the game.
6)So all the people with P4 processors with integrated Intel graphics chips need not worry. No need to buy a new computer, Just buy a 128 MB Graphics card. Its probably a little expensive but Nvidia 6600 is a best value for money graphic card out there.
7) and all the people with 2-4 year old laptops I am afraid ur baby is not good enough to handle BLC 2005, so rather don't buy it. PLay the demo first.
8) And for people who don't know what' s an AGP is then here's couple of pictures they can refer to.
The Black slot in the first picture is AGP slot. The second picture shows how to install a graphic card into the slot.
So i believe, this would have answered everybody's questions and would have cleared any doubts. Still anything else I am happy to answer.
Thanks
