Doesn't look like it. Heres what Microsoft says : How do I revert back to using an older version of DirectX? - Microsoft Community

Have you considered trying your games in a Virtual machine? (assuming you have an older MS OS disk)

i really dont want to do a virtual machine considering my external GPU

is there any way to force the GPU to run DX 10.1 or 9 only?

Nothing to do with what the GPU supports to a point, and everything to do with what the game supports. If a game is DX9 only, then that is all it will run at regardless of whether the card supports a higher version. If the game supports a higher version, there is usually either a setting in the in game settings to select a lower version, or running at lower settings will force it to run at a lower DirectX version.

There is no way to force it through the driver or Windows.

I believe not.

Some games have mode settings to only use limited DirectX settings (like DX9).

i dont understand why my DX11 games run awesome! and all my DX9 games are unplayablely laggy. ?!?! i got latest drivers etc...

You install this yet?

Download DirectX Redist (June 2010) from Official Microsoft Download Center

Directx is built into windows from what I understand. Read ...... somewhere....... that you CAN uninstall it , albeit with much gnashing of teeth and sorrow, but from what I gathered from MS theres other things that need it. I'm ASSUMING DirectX has "hooks" in it and each version is different. When I looked for the link I posted for you I DID find a place there (MS site) to download DirectX 9 , but not sure if you could get it on your machine from the admittedly cursory fast read.

Yeah I saw that too, but wasn't sure it was what he needed. Was just going back to see/link it for him. Thanks for beating me too it!

 

[Quadrider10]

yes ive installed that link, and it did no help. i alsoi tried to install dx9, but it wont allow me. says a newer version is already installed... it just dosent make sense that both my directx 11 games run awesome, but dx 9 games suck no matter what the graphic properties. all dx games worked fine before my new GPU.

Why I mentioned earlier about the uninstall of DirectX. I knew you couldn't just install an older version, you'll have to root out every trace of 11 and then there would be no guarantee that you could install an older version or even that it wouldn't mess up your system totally. I don't remember where I read the steps to uninstall or I'd link it for you, sorry.

Only reason I can come up with about the "why" you asked is...... just different versions written different ways.

Maybe a driver/firmware rollback for your GPU? I'd be mighty careful there..... have you gone to the new gpu's maker and asked there?

its done it on 2 separate GPUs. a 6670 and my current 6770. rite now im on the bata driver for the 6770 and it seems to help a tiny tiny tiny bit. but still sucks....

thats what im saying! its really freaking annoying!!!!!! :devil:

 

[Quadrider10]

Any other ideas?

 

[indianacarnie]

Compatibility mode maybe? Running out of ideas to tell you the truth. I'm going to be pretty busy today, but I'll see if I can find anything else when I can.

i think running in compatibility to windows 95 might help. havent been able to fully test it tho.... thank you very much!

 

[indianacarnie]

You're very welcome, let us know if it works to your satisfaction. Kinda busy today,getting everything packed up for the road, but will check in when I can and also see if I can find anything else. (Just in case)

ok np thnaks! ive tried in vista and XP SP3 and those dident help at all.

 

[Quadrider10]

ok so running in windows 95 defientially helped, but shadows suck now lol. no biggie, but im still getting lag spikes and stutters. i had to lower the resolution to 1600x900 to get to where it is. it defientially helped a big time tho! but maybe its not direct x? like its still no where near as smooth as BFBC2 or dirt 3....
