Currently on an old compuer(VERY OLD) for a month or 2 because mine is broke and im too broke to fix it.It has shaders 2.0 but i wanna play games like FIFA 11 which require shader 3.0, I have 256 mb of video ram using an integrated graphics card and 4gb RAM with a 2.4 ghz processor.I just saw something called swiftshader which emulated shader 3.0, will it work on my machine?will it lag?
