My video card is DirectX 10 ATI Radeon HD 2600 Pro 512mb. The latest
Catalyst driver 8.4 is installed.
Windows Vista 64 "Performance Information and Tools" shows that "Graphics:
Desktop performance for Windows Aero" has 4,8 Subscore and "Gaming graphics:
3D business and gaming graphics performance" has 4,9 which are very low,
that the HD 2600 Pro is the bottleneck of my computer.
Why does Windows Vista score the card so low?
How to improve the performance of the card?
