I've just bought "GT Legends" and although it runs, the framerates are poor (average 15 - 20). The manual with the game recommends :
--------------------------
Operating Systems Microsoft Windows XP Home/Pro, x64
Processor 2 GHz Intel Pentium IV or 100% compatible
Memory 1 GB RAM
Hard Drive 2.5 GB free space
3D Accelerator DirectX 9.0c compatible graphics card with 256 MB memory
Sound Card DirectX 9.0c compatible
Input DirectX 9.0c compatible force feedback steering wheel
DirectX Version 9.0c9.0256MB

.................................................. ..

so it looks as if the graphics card is the weak link.
PCI or PCI-E? Radion or Nvidia?
I could do with some advice.
Thank you very much
