Windows 7: How to force direct x 9?

as the others say, bc2 is a pretty demanding game, hardware-wise - it's never going to run smoothly on an ordinary laptop.

however, to answer the original question - if you want to force dx9 in other games, running the game in xp compatability mode should do the trick.

right-click on the program or shortcut >> properties >> compatablity >> run in xp sp3 mode

Try installing DirectX End-User Runtime, it will install missing files of DirectX 9. However, DX11 doesn't have every earlier DX9 files, many of them are missing.

Please see steps 5 & 6 here - Tips on Troubleshooting Game Issues. It explains the whole DX11 to older DX versions relationship.

Bottom line is in order to play DX11 games 3 items must be DX11 capable....

1- OS (software) - Windows 7 is DX11 capable
2- Game (software) - Game must be DX11 to be played in DX11 mode!
3- VIdeo Card (hardware) - If cards is anything other than DX11, no game will play in DX11 mode!!!

Bottom line is the system will play in the lowest DX mode available between the 3 items.

Hope this help.

This was more than likely part of the installation of the game. Just about every game I've ever installed puts the dx distributable on your machine.
The game in question is dx 9c anyhow.

Dude, running DX 9 isn't going to make it any better. Your laptop doesn't have the hardware needed to run the game smoothly. The only thing you can do is upgrade your graphics card if you can and add ram. Other than that you will have to get a better platform for playing BC2.

Well if the game in question is DX9 than the OP doesn't need to "force" it because it will be run in DX9 regardless of the fact that Windows 7 is DX11 capable. See my earlier post.

Yeah it sucks to buy a game without understanding the minimum requirements.

Here's a thread with different tweaks to get your game to run better including the DX-9 entry you said wouldn't work.

NOTE for dual-core users to maintain fluid gameplay - Electronic Arts UK Community

You can also install XP on a partition and run the game in XP. It runs this game more efficiently. Not sure that would really help you or not but it did help me when I was running a dual core. Gave me +20 FPS.

actually it defaults to dx10 if you have dx10 supported graphics gpu. My first post cleaned up that though.
