Quake 4

Although the RADEON X1300 PRO and the RADEON X700 look much better in Quake 4 than in Doom 3, they still have not a single chance against the XFX GeForce 6600 GDDR2. For some unclear reason the performance of the RADEON X1300 PRO goes down dramatically in 1600x1200 resolution. It is, however, a little faster than the RADEON X700 and just 2fps behind the GeForce 6600 GDDR2 in 1024x768 with enabled 4x FSAA and 16x AF, all these graphics cards, except the GeForce 6600, giving you a playable frame rate in the latter mode.
