A question about DX
 

Perhaps a silly question..

How does one tell if they're running DX9, DX10 or DX11?

Run dxdiag.exe.

Thanks for the faster than quick response! :)

hell i have windos xp with only dx9

That sucks - but presumably dx9 will be supported when the patch is finalised.

In the conf.ini there should be a line in the [windows] subsection
renders=D3D10_0.

DX is backwards compatible.So a DX 11 capable card can run DX11,DX10,DX9,etc.

If I recall correctly DX10 is only available on Vista and newer OSes.

since patch i cant get my game to work, it loads up but i get black boxes in plane loadout screens and no maps then it crashes to desktop when trying to start mission.

when i ran dxdiag it says ive got DX11..... do i need DX10 only and if so how do i downgrade

no. Probley a currupt download, redownload.

Check yuor installing it right.

If you have DX11 installed it will run DX11 and below.
