Force DirectX 9?

I know thaqt when possible windows 7 loads any game with the latest version of DirectX, if compatible. Is there any way to force it to load a game in DirectX 9?

Note: game is compatible with directX 9,10,11

Hi CallmeEclipse.

Try running the game from a shortcut with -dx9 appended to the end.

For instance for Bioshock: "C:\Program Files\2K Games\BioShock \Builds\Release\Bioshock.exe" -dx9

Note there is a space before -dx9.

Hope this helps.

Might help to know what game? Seeing as there are only two games out so far that support DirectX 11,

List of games with DirectX 11 support - Wikipedia, the free encyclopedia

and I know that GRID 2 is DX 9 and DX 11 (there is no DX 10 in it). Battleforge does support all three. If the game and hardware support it there will be (or should be) an option in the game; some like Crysis have it in the right click/context menu on the shortcut, another like ANNO 1404 only enables DX 10 when a certain setting is enabled in the in game options.

No it doesn't, it is entirely dependent on which version of DirectX the game uses and whether the hardware supports it. The only way for a game to run using DirectX 11 is for the game and the video card (currently ATI's HD 5xxx series of cards only) to support it.

True.

Also note that some games will give you the option to choose which DX Version of the game you want to run either by game launcher or .exe file. Example - Bioshock, Crysis, Lost Planet. (All DX 10 games)

I say some, but it could/might be all if they're multi-dx games. I just know about the ones mentioned above.

What about it? It still won't run in anything other than whatever DirectX version is supported by the video card.

By the way, would help to now what video card you have.

uhm, im not sure you are getting the point, my Pc completly supports Dx11. the point was to get the game to run in dx9, because windows 7 automatically runs in the highest supported by the game (as long as it is compatible with your card). however i foced the game to load into dx9.

I edited the exectuable file to where it thinks dx9 is the highest it can go, or so thats what it tell windows 7. problem solved.
