All tests were run with 6 times FSAA and 16 times Antistrophic Filtering enabled with the screen resolution set to 1024 X 768.
When running these aggressive detail settings in 1600 x 1200, games really do become unplayable and if people are after image quality they will have to drop the resolution back down to reach playable levels.
1024x768 was chosen as it is still the preferred playable resolution with these settings enabled.
The 9800 XT has only managed to increase its lead over the 9800 PE when we enable high quality graphics settings.
Unreal Tournament 2004
The 9800 PE is just playable here in UT2004 at this level of graphics quality.
Simply put, the 9800 PE doesn't have enough power to run Doom 3 at this level of detail - even the more expensive 9800 XT is finding it hard to keep up.
Again we have a similar story between Doom 3 and Far Cry here - the 9800 PE just isn't built for this level of graphics quality with recent release games.
