EXE and directx compatibility
 

Hey, I was wondering if Linux runs .exe files, or directx at all. If not, does it have a work around for either of these?

Not sure what the relation between .exe and direct-x is....

.exe is a Windows executable and--without help--will not run on Linux (Or any other non-Windows system).

In Linux, we have WINE, which attempts to re-create the Windows API on Linux. It works for some things and not others. CrossOver Office is a commercial port of WINE in which certain things are guaranteed to work.

go to the WINE and CrossOver (Codeweavers.com) sites to learn more about the speciic app you want to use.

There is also Cedega for games.

what about directx? what does linux use instead?

Linux really doesn't have - or need - a DirectX-like application/library.

Seeing as DirectX is really just used as hardware acceleration for games and such, the closest thing could/would be Cedega.

Most Linux apps that require high performance 3D graphics use OpenGL (which is also available for Windows).

yes, but opengl is much crappier than directx

so my question is, does "cedega" support many of the games that windows supports?

And a follow up question, will my 512 nvidia 7900gtx graphics card, and amd x2 dual core processor be taken advantage of by using linux?

There's an official compatibility list for Cedega at transgaming.com here:

Be aware that Cedega does cost money, however, as does Crossover Office. Wine is free though.

Only if you install the proprietary Nvidia graphics drivers will you be able to take advantage of your video card. How to best install it depends on which Linux distribution you choose.

In addition, your dual core processor should be detected automatically. You should be running a "smp" (multiprocessor) kernel, which will sue both processors.
