Also, it's curious Th0nt thinks it must either be biased, or AMD haven't been optimised, rather than performing as they should in an FPU heavy game that looks to be heavy on 4 threads. It's obviously using later instruction sets too.
RTS is not a strong suite on AMD CPU's.
I'm not going to deny there might well be some optimisations they can make, after all this is the nature of releases rushed by Sega through the creative assembly these day. But this game was always going to highlight the FX weaknesses rather than their strengths. There are many who are claiming this is already a much smoother launch than RTW2
