Colorspace Conversion

The Colorspace Conversion tests should be passed by any current generation graphics chipset which is the reason why it only accounts for 4% of the overall quality score.  The test simply makes sure that the graphics adapter can perform a colorspace conversion on the fly (YUV to RGB).  Colorspace conversion is necessary when the video data is stored in YUV mode and needs to be converted into RGB data for display output.

All decent cards should pass these tests, and as you can tell by the above chart, all of our contenders did. The only thing we'd like to note here is that the 3dfx cards did seem to produce a much more washed out rendition of the test image than the rest of the cards, however the cards did pass the test.
