I'd like to add that this issue doesn't occur if i reduce the resolution to 2048 from 2560 ...

however in 2048*1152 things are really ugly...

cheers

How are you connecting DisplayPort to DVI and getting that 2560 resolution?

If you are using Apple's DisplayPort to dual-link DVI adapter then that might be the problem. That thing has a bunch of electronics to decode the video signal and re-encode it.

I see you are connecting to a Cinema Display. Do you have the 2010 model? That should have a DisplayPort connector and you should be using that instead of DVI.

Hello Motrek,

Ah okay, your original post said DVI so I was confused.

I have no idea why it's slow, sorry. I have a similar setup and it works fine for me.

No, my understanding of Bootcamp is that it just lets you dual-boot Windows, so if you aren't in Windows it shouldn't have an effect on anything.

Why don't you check and boot up in OSX, if you still have it on the machine.
