I've been having a couple of problems with DirectX 9a. Since installing it, I cannot run some games that have always worked on my pc since I installed DX9. These are FIFA 2003 and Grand Prix 4. Both these want DX 8.1, but I know DX9 cannot be uninstalled, and running a DX8 setup program doesn't do anything because it logically doesn't update the 'newer' files. I run Win. Me, have a GeForce 4 graphics card with latest drivers. Any ideas...
I installed dx9 and ended up with serious graphics issues Im on xp with a gforce 2mx On using my restore point I couldnt get it to run at all in the end I done clean install and just use 8.1 machine has been super since
Especially if your running an older graphics card, wait till games appear that actually make use of it, and even then i would only upgrade if my graphics card was directx 9 capable. Alot of problems with direct x 9 if you go to other forums, esp. graphics card ones.
its backwards compatable.if everything is ok with 8.1 then leave it as above you wont see any improvement even if you card supports it,for a while yet anyway.but if you are having problems with 9.0a then give this a try.i had numerous crashes with it and none with the final version better than a reformat and less risky than 3rd party uninstaller.
