I have just put all the bells and whistles on - the UTs, GEX, ASX and XGraphics and the world of FSX is phenomenal.
Except for one thing.
At SP1 Aces went back to FS9 batching of scenery in order to help those with older and/or slower systems.
I flew in Nova Scotia, hard winter, and my eyes were killed by the flicker of trees popping up ahead as the next batch arrived.
