Well I don't know exactly what is causing the slowdown in terms of hardware/software/bugs...but there is a definite link to the Target Damage highlight button.
Like you I wonder...did no-one use Target Damage in testing? It's a very important button.
However, I'll be more than happy with my purchase when this issue disappears.
if you look at any of my AARs you will see I use nothing but the Highlighted Damage, these were not a issue except for people with Quad Cores systems, and not every Quad Core system has this trouble
my Vista 64 runs the game better then any of my other computers, and from the Forums, it looks like AE was caught by surprise by the same issues
