I am hoping something went wrong with the distribution, as performance for me is also bad.

My CE edition unlocked yesterday evening in Australia and I gave the game a quick run last night after getting home from a meeting.

My system specs are as follows:
i7 clocket at 3331 Mhz
ATI Radeon HD 5870
RAM: 6142 Mb
Windows 7 64 bit, running off a SSD

Running at 1920x1200 resolution I was getting only about 20fps with the graphics turned down.

This morning the option came to turn off the eip-filter, and unfortunately I have had no significant increase in frame rate.

Neither the graphics card nor the CPU is heavily loaded during flight. There appeared to be only one CPU being loaded by the game as the other 4 only had slight loads which I would have accounted for the system monitor and fraps.

I have not yet turned off head shake as that was turned on in my settings.

In comparison I ran up my copy of wings of prey. I run that at 2560x1600 with detail on max. Flying around the south of England (with similar number of trees/buildings (and I will say more realistic looking trees/buildings) I am able to achieve over 60fps on the same rig.

There appears to be a bottleneck somewhere that is preventing the software from utilising the hardware available.
