Performance Issue
Hi, I just upgraded my graphics from an 8600gt to a HD 4890, and have experienced extreme framerate decreases in game. Whenever I view a moderate amount of units at once, the game framerate quickly drops down to around 5-15 fps.
Strangely, there is hardly any framerate difference in-game between high and low settings.
I have updated to the latest graphics drivers and this has not made any difference.
Specs:
xfx ati hd 4890
3 gigs ram
athlon 64 x2 5600+
vista 32
