Hello, Be aware of the fact that: a) Windows 7 is using 3D hardware even for desktop (Desktop Windows Manager uses it) b) 3D optimization viewer uses OpenGL (and this means 3D hardware) c) if you are using your computer for example for video en-/de-coding too, certain softwares use CUDA/OpenCL - i.e. general computing on graphic card to speed up the process. Then graphic card performance counts.
NVidia 8800GT may be old but it is great and very capable card. Best regards, Tomasz Janeczko amibroker.com On 2010-07-24 16:02, Rob wrote: > Thanks.
