I tried the 512 texures , lower frame rates
It did say that anything but the "default" would be lower , as 1024 is my "default" then that made sense . I wonder why it's that high for "default" ???
I tried the game in 1600 by 1200 with the pc set to best proformance and it really looked pretty

flew ok till more than a few showed up at a base we were trying to take

I then reset it back to 1024 by 768 and left the pc at best proformance . Works fine no stutters at all .
I do find that FS 2004 works a bit better than with my old card IMO . I do see the delay in bringing up differant stuff and view as I did before . That's a good thing .
I am thinking that AH used cpu more than video , unlike FS 2004 ?
