HOW DO I DISABLE A GPU????

[heroofspirits]

hi there

at the moment i am using a hd4870 x2.

i have noticed while playing games i get a lot of micro stuttering. and yes i can see it.

i want to disable a gpu on the board so i can play with just one, only i dont know how to. i am doing this as 1, want to check on the micro stuttering if i only have one gpu and 2, see fps on one gpu.

will reanable latter so probs need to know how to re enable

am using x64 vista and 7 rc. ccc 9.5 (the newest one)

thanks!

It should be possible to do this seeing as AMDs drivers disable a core for games that don't handle CF well. (GTA4) I don't think they allow you to do it for just any game however.

Don't be too surprised if you can't do that, one of the downsides to Xfire/SLI on a stick cards is that if there is any kind of issue with one GPU then you are boned. That's why I dislike them .
