Hello Kocmoc,

I have old hardware and 64 bit Win7. I don't have the OS installed on the faster and bigger hard disk yet, so I'll get some free optimisation soon.

The hardware is:
Asus mobo, socket 775
CPU Core2Duo E6850 @ 3 Ghz
DDRAM 2 GB still, running at 400 Mhz
GFX some Nvidea 7950 with 512 DDR
3 SATA hard disks (the game is on a different one from the OS)
LCD 1600*1200 pixels at 22"

The demo is running at medium graphical details, it feels a lot faster than the NTW demo which I tried a few weeks ago. I'ld even call it smooth, both the campaign and the battles. But sometimes it's really laggy, starting at the into screen (Sega, CA logo); nothing is running in the background.
Sometimes it loads the campaignmap and allows me to move the camera around, be it laggy. Then suddenly the screen turns black and the game loads again.

Summary:
Generally smooth
Sometimes very laggy
Sometimes the game automatically reloads

How is it running for you?
