I recently installed assassin creed 3. I have the following config amd a8-4500 radeon hd 7670+7470 dual graphics and 4 gb ram. The game is running extremely slow about 12 fps. So i downloaded this radeonpro and found that i was running dx11 version of game. The previous games had dx9 and dx10 launchers. But this one only has one icon named ac3sp.exe. Is there any way to force the game to run in dx10 mode?
right click the shortcut to the program, go to the properties tab, then in the target box add " -dx9" or " -dx10" without the quotes after the link. Save, then try running the game again from that shortcut.
