yes,,, i got the z buffer / flickering/ drivers may not support message .
my drivers were still working in beta 27 with that message,,,
beta 28 messed it up though .
I installed the 56.64 drivers and now it works .. the fps isnt bad 25-50 but the eye candy is really down low now . (i turned it up from the default settings to about 80% up)
these drivers seam to be ok they work with all my other games also (the 42.xx's messed up everything)
Im getting frame freezing when attacking buff formations and or when my plane is smoking bad ... sometimes it even ctd's me .
I havent had a chance to play lately on my 2.2ghz ti4600 pc yet .
