Good morning all!! (And sorry for my english i'm italian :P )
I have same problem here,this game can run at high details or medium or ultra but...
frame rate is very slow from 16 (ultra - high) to 25 (medium).
If i use a smaller resolution the game goes a little better.
The problem is, that in the video option, i'm not allowed to choose my dedicated Radeon graphics
because this game doesn't see it.
I am using a laptop Hp pavilion that run perfectly Diablo3 on ultra (this is just for a reference)
These are the stats on it:
Model: HP Pavilion dv7 Notebook PC
Intel(R) core(TM) i5-2410M CPU @2.30GHz 2.30 GHz
RAM 4 GB
64 BIT
WIN7 service pack1
Video: AMD RADEON HD 6700M
Can u help us to solve this problem? Thanks!
PS: the game rocks!
