I've just worked out that there could be a problem with my ATI Radeon HD 5670 1GB. An application is using the graphics hardware to resize an image to fit the screen, but it's not really sharp enough. If I configure the application to do this in software instead, it looks better.
I have been aware of this issue for over a couple of years, but have only just discovered the workaround. I have tried changing settings within Catalyst Control Center, but it makes no difference to the hardware rendering quality. To be honest, I'd be surprised if any of the settings I see are relevant.
I am working in Adobe Bridge CS6, but it was the same with CS5. My OS is Windows 7 Pro 64-bit, and the Catalyst drivers are currently 12.8 (but have used several older versions).
Can anyone suggest a way of improving the hardware rendering? Or do I need to get a new graphics card?
