I wondered if anyone has tried a direct x 10 card with some older games in particular Unreal Tournament 99 and how it performed. i play quite a few old games and am a little worried aboutt he backward compatability of this new card. the card im lookin at buying is the NVIDIA 8800 GTS.Im guessing they may release drivers that give it compatibility with old games like this, Im sure there is an option in Nvidia control panel with settings for specific games.This is a kinda / maybe (still not sure) <<    copied from another site*

I don't know about DX10 WORKING with NORMAL windows XP (I don't think it will, but i'm not 100% on that.... in fact it might work perfictly). As for the graphics cards, technically you'll need to get a new one (G80 and R600, which come out at the end of this year, are supposed to be DX10 compatable), however all DX10 games will be backwards compatable with DX9, at least in the imideate future, until vista and DX10 become standard, as not every person is going to be able to get a DX10 card right AWAY. So, to answer your question, you should be fine with getting a DX9 card now, and then after G80/R600 come out and all the kinks in vista and DX10 are worked out, upgrading to a new card when you can.

I have this card.  I havent been able to play any of my older games (Halflife 2,Quake 4,Zero Hour)

When I load them it just crashes to the desktop...tis a shame I have no good first person shooters out to test the card with.

No actually i know why it not playing the games use these instructions on the bottom on the games to see if that helps, plus if yall run vista it will be the same directions

Many older computer programs may not run correctly if you just click on the program's executable file in Windows XP; this is particularly true of older game programs. There can be many reasons why. Perhaps the program uses DOS calls that XP does not know about. Perhaps there are graphic hardware considerations. Perhaps...who knows.

Indeed, some older DOS-based programs, in order to speed up the display, wrote directly to the computer's hardware. These, Windows XP will not allow to run at all. In order to run these you will have to find a computer with an older operating system.

For those in between, there is some hope in using Windows XP's Compatibility Mode.

Open Windows Explorer and navigate to where the program is located. Then...

Right click on the program file (the .EXE or .COM file).
Select Properties from the menu that pops up.
Select the Compatibility Tab in the dialog.
Change the options so the program opens in Windows 95 or 98 compatibility mode. Note the other options in the dialog as you may have to experiment a bit and change some of them as well.
