Hi guys,

As above.

Game loads OK, but once I hit the menu I get a major flicker and cannot see the whole screen.

I am running at 1920 x 1080.

I have tried 800 x 600 but same problem. Have googled to no avail.

Microsoft Windows 7 Home Premium 64bit with SP1 OEM
Powercolor Radeon HD6990
ASUS P8P67 PRO Motherboard B3
Intel Core i7 2600K
OCZ Agility 3 120GB SSD 2.5"
Silverstone Strider Plus 850W
CoolerMaster Hyper 212+ CPU Cooler
Samsung SpinPoint F3 1TB HD103SJ
G.Skill F3-12800CL9D-4GBNQ (2x2GB) DDR3
Lite-On IHAS324 24x DVDRW

What game I-War or EoC?

EoC

Try turning v-sync on (possibly within your driversettings).

I have the same problem, where screen flickering is covering every bit of the menu - except the new game option, and have tried this with no luck.

I dunno, can be a lot of things, anti-virus, UAC, Windows permissions, etc.
Try contacting support if you cannot get it to work.
