RTW Issue With GPU

[paluza]

I can't find solution to this anywhere. RTW doesn't see the dedicated gpu (Radeon 7970m) on my laptop and uses hd4000 instead.
It's hard to search for a solution due to the second part having the same issue (that is fixable BTW). I tried running it in compatibility mode (Win XP SP3), but that way it doesn't run at all (when I launch it, the resolution gradually goes down to 600*800, and the game crashes giving we an alert window with "Rome: Total War" and nothing else in it).
I have to put everything in medium, and fps is still pretty low (around 20).

Did you disable the hd4000 in your bios?

If not, you should.
