![]() Video - Basic Quality |
Our test results prompted a phone call from AMD, to confirm what settings and tests we used on the cards, and to let us know that a non-mature set of drivers was released to the press with the sample hardware. As we were testing not at 2560x1600, but at 1920x1200, it was not expected that there would be a perceivable image quality difference. This happens from time to time, as hardware is released and driver revisions put out to get all functionality working. AMD has now provided us with an early beta of a new driver package that is intended to resolve the issue.
The CCC Video settings pages contain options to improve or tweak video playback to your satisfaction. Out of the box, as it were, the options for automatic deinterlacing method and enforce smooth playback are checked, to provide the simplest and easiest way for consumers to get great video playback.

Using the new drivers, we retested both the AMD ATI Radeon HD 5450 and HD 5750. Technically, the HD 5450 should have enough shader power to perform vector adaptive deinterlacing and maintain smooth playback. Using the Advanced Color controls along with Enforce Smooth Playback might result in some of the advanced color options being skipped as the shaders load up in complex scenes. However, the new drivers allowed the HD 5450 with default settings to use vector adaptive deinterlacing and maintain smooth playback, without a loss in quality.

The AMD ATI Radeon HD 5570 with it's Redwood core has a lot more shader power than the Cedar cored HD 5450, and so should have no trouble processing Advanced Video Controls and Vector Adaptive Deinterlacing at the same time. AMD expressed surprise at our results showing a drop in quality when using Enforced Smooth Playback, which prompted the call. Retesting with the new drivers shows the HD 5570 powering through the Cheese Slices, no discernable difference in quality when using different settings - even with Vector Adaptive Deinterlaced forced and Enforced Smooth Playback selected.
