I'm using a Geforce 6800 ULtra video card. While I was watching a replay of my landing, my 4x FSAA and 8x AF switched off. After the replay still the settings were switched off. I have a profile for FS2004 to set with 4x FSAA and 8x AF. I restarted FS2004 and my profile display settings for my video card worked again. What's caused FSAA and AF to turn off automatically in FS2004 while watching my replay.

I cannot tell you definitively what's causing the problem, however why use a profile instead of turning AA and Anio on in the control panel globally? Personally, I have never used the profile feature, and it doesn't bother me to switch modes depending on the game I am playing (only takes a second or two). What drivers are you using? Who makes your 6800 Ultra?Mike :-wave P4 3.2E @4.00ghz 250FSBDFI Lanparty Pro875B Rev B1gb Corsair XMS PC3500 2-3-3-6 @2.75vNvidia BFG 6800 Ultra OCSB Audigy2 Platinum ExSony CPD-G520 21' MonitorLiquid Cooled GoodnessPics: http://community.webshots.com/user/chksix2002 (NEW Gallery FS9@ 2048x1536!!!)

The reason I use profiles is because of convenience.

Well ok. I don't know what could be causing your problem other than the use of the profile function. Try using the global setting instead of the profile for a change (temporarily to see if it clears the problem). The only way to help narrow this down is through a process of elimination.P4 3.2E @4.00ghz 250FSBDFI Lanparty Pro875B Rev B1gb Corsair XMS PC3500 2-3-3-6 @2.75vNvidia BFG 6800 Ultra OCSB Audigy2 Platinum ExSony CPD-G520 21' MonitorLiquid Cooled GoodnessPics: http://community.webshots.com/user/chksix2002 (NEW Gallery FS9@ 2048x1536!!!)
