As we mentioned before, downscale quality will only increase in importance as time goes on, especially once video sources start readily being offered in resolutions greater than 720 x 480.
The ATI Radeon has what it takes to meet the demands of the future as it perfectly displayed all lines in every situation except for the 20% vertical downscale test. The NVIDIA cards came close, and the G400 can be considered for a distant third place, however other than that there were no runners up in this test.
The Voodoo5 was quite disappointing as it, being a recently released card, was still unable to reproduce any lines in a number of the tests.

ATI once again took the lead in terms of quality as it was able to perfectly reproduce all of the original lines in all but two downscale quality tests.
The NVIDIA cards are somewhat close to the Radeon however other than that there are, once again, no real runners up.
