Official Tested and Confirmed DSDT Graphics Edits

[kiyyto]

Am I right in thinking that Radeon HD users of the 5000 series do not have to do this?
That our cards are already supported by OS X?

I know that we need to edit the DSDT for HDMI sound, but other than that there is no other reason, right?

Please do not ask me what is "driver-ist" all I know is that without pulling a value for that from the ioreg and putting it in my edit I cannot get rid of graphicsenabler, but with it I can set graphicsenabler=no and get full performance. I have asked the question myself about what this is in a separate post as maybe it'll be interesting or will help someone.

Do I have to be using a motherboard with a DSDT or is it possible to just inject this for my video card. How can I accomplish it?

Hey tony, what about geforce 450 on mountain lion?? i have that one, is necesary edits the DSDT to enable full QE/CI ? or what about it, or just i can install the open cl Enabler from multibest? im on Lion 10.7.4 and i want update with unibest method but i dont know if my hardware are supported, I have motherboard Intel DP55sb Ge force 450, i5 750. Many Thanks

Here are my DSDT edits for my geforce 560 ti on an asus p7p55d. It took me many edits and reboots to get this working. Works great on mountain lion.

This is my edit for a pair of 470GTX cards with fully working native HDMI in a MSI P55-GD85 mobo, The code should work on any MSI P55 board you may have to change the POP address tho, for non MSI boards you'll have to drop the POP
