I can`t play games normally with directx 11


Dec 18, 2012
Recently I installed the game Assassins Creed 3. It updated my directx 9 to directx 11. I played the game perfectly,no problems at all. Later I decided to play Assassins Creed 2. It requires directx 9 but I read that I can play the games that require directx 9 with directx 11. When I loaded the game it was so slow, both sound and video crashes like all the time. I don`t what the problem is. Can you help me?

if is windows XP then you have installed a false DX, because does not exist DX10+ for windows XP, only DX9.

'but i played dx10 games on windows xp...' DX 9.0C or 9.0L (for systems with Windows Vista+ with no DX10 support) also run DX10 games

'But i downloaded an DX10/11 pack for windows XP...' No you downloaded the complete DX9 with all redist files

'but it says DX10/11 on DXDIAG.exe...' its only an string you can change it for what do you want, if you know how to do

but as i say first how Operating System are you using?
