Catalyst bug


on Win 7 64 bit, HD 5770, catalyst 12.8, when I'm watching a flash video (youtube), and I'm running a 3D application, the video card's clock speeds won't go to max, therefore the performance is not enough.

In idle the 5770 usually goes by 175/300 MHz (gpu/mem), when I'm watching flash videos it goes up to 400/900, and when it only displays 3D application it goes up to 900/1200. Now if I watch flash videos AND 3D stuff, the driver gets lazy and forgets to set the clock speed to 900/1200, therefore the FPS gets halved. I ran a custom 3D app, so I suppose when it's not games (therefore there's no application profile in action), the driver just ignores that there's a 3D app running.

Please fix this in the next Catalyst release.

Best regards,

Fixing in the catalyst release is fine but what about the problem of excessive clock speed and reduction in FPS. Please advise solution
