ok until now i could manage this "thing" with aa and af. i lost them everytime i switched to windows while on the track, but if i went to garage screen then window then back in-game aa and af were back again. now i dont know what happend but doesent work anymore i cant get aa and af to come back. i reinstalled the drivers before i cleaned them with drv cleaner but nothing. if i select the profile in ati tray tools, the game runs and everything is fine until i window the game. then when i come back, no aa and af and i cant get them back i tryed everything! plz help its absolutely horror withouth them.

thats very old bug in ATI drivers.ATI nor NVIDIA suggest to use ALT-TAB as this cause issues.

I had that when I had ATI8500 running on 5.10 drivers before Catalyst came out.This should be reported to ATI but I think they will not care because they will say you used ALT-TAB thingy.Although NVIDIA drivers doesnt have this issue.

Sorry I couldnt help.

yea well i know, i read the threads about this when i first encounterd the issue but it was manageble until now. i really dont know what changed this? and why? i didnt install anything new, no programs, drivers, or devices...it just happend all of the sudden. strange, and annoying.

Alex check out this thread, seems many people are having this issue especially with the latest drivers (catalyst 7.4): http://www.lfsforum.net/showthread.php?t=23067

i read that thread evin befor i posted this1, but didnt helped much...i would want to find out what caused this problem. the thing is i cant restore my system because i disabled the option from windows...so i cant comeback to the old settings. but i'm still wondering how is it possible that with no manual intervention to the system what so ever something changed and now i cant restore my aa and af in lfs.
