no anti-aliasing at "higher" screen resolution

[mump 0]

Hi, it's me again...

 

I am a bit confused. When I run FE using 1280x1024x32 (same as desktop resolution), I have no anti-aliasing and lots of jaggies, although I turned AA on using the ATI tool. At lower game resolutions, I see the impact of anti-aliasing. Do I do something wrong?

 

I have a rather old system (Radeon 9800).

 

Thanks in advance for your help!

perhaps upgrade to a new card, i was running the Wo* series on a tired old 9800 pro for a long time. then i found a newer x1650 pro 512meg card on newegg.com for under 60 bucks. greatest agp upgrade i could do at the time, now all the series work wonderfully with AA settings higher and resolutions higher.
