New AMD GPU Driver OMEGA - Working@Bootcamp

[mattvv]

What does it say under your Display Adapter Now?

I have the base model iMac 27 5k mid 2015 with AMD Radeon R9 M290.
The only method that has worked for me is:
Right clicking on the AMD Radeon R9 M290 to uninstall with "Delete driver software for this device." checked.
Install Catalyst 15.7 drivers (15.7.1 doesn't work with this method)
After installation, I right click on Microsoft Default Display Driver to update driver and choose the location where Catalyst extracted files to which is: c:\AMD\AMD-Catalyst-15.7-Win10-64bit

My Display Adapter should say: AMD Radeon R9 200 Series.
Instead it says: AMD Radeon HD 7800 Series.
Which kinda makes sense as R9 290 and the 290x are rebranded cards as per ExtremeTech:

The GPU powering the 27-inch iMac with Retina 5K display is the R9 M290X, with the R9 M295X offered as an optional upgrade. The R9 M295X hasn’t technically been announced, but rumors from months back suggested this would be a Tonga-class GPU. Regardless, the R9 M290X is the minimum spec — and that chip is a rebranded HD 8970M, which was a rebranded HD 7970M, which is functionally equivalent to a desktop Radeon HD 7870.

After this installation, some 3D programs that didn't even load up properly now start up just fine.

@Alyssa - where did you get the 15.7 drivers? I'm trying to find them but i'm only directed to 15.7.1

Found the drivers doing some digging online - This method does not work for the 295X, I'm guessing yours is a 290X?

I have the R295x..

Had to ensure it was only showing Microsoft default adapter when performing the upgrade.

Shows as the below after now.

Sorry duke, I was addressing @Alyssa in this one. Your method works fine.

No, mine is not the m290x its just the m290.

@duke748 Thanks for posting what your display adapter name after installing Catalyst. That seems to be a driver closest to what you really have.

For those not aware yet. New Bootcamp released today. Version 6. Comes with Windows 10 support.
My Display Adapter now correctly appears as AMD RADEON R9 M290.
Still no 5K support though. 4K is the max.

FYI i now have full 5k RES in windows with the 295X, i only updated today so unsure how long or if this an update after the previous post. I had to increase text size to 200% to see it

but Native res is now

5120 x 2880

Could you tell us what the display driver version is? Also are you in Windows 10 or 8?

My display driver Bootcamp Assisant downloaded on (2016-02-25) was 15.200.1060.0 but I wasn't getting 5K resolution under Windows 10. So I downloaded the Apple Graphics Bootcamp Drivers from AMD. Now I'm at 15.201.1301.0 but still no 5K resolution.

I was using Windows 8.1 and that had 5K resolution. Now I'm stuck at 4k in Windows 10

Apologies for the 'no new info' bump. Sorry if I got your hopes up.

Anyone got anything new to report on this?

M295X iMac 5k here running Win 7 - still stuck a little south of 4k.

And while I'm here....

Any other 3d artists find that in Bootcamp you keep getting these weird artifacts a lot of the time?

I had it in Max, and it was so bad it was practically unusable - but changing to a previous viewport driver (graphics driver in Max, nothing to do with hardware) solved it.

Here in Substance Designer though - I can't seem to change the viewport driver (or can I?) and these damn checkerboard glitches keep showing up all over.

Any ideas? I mean... apart from 'give up trying to do 3D artwork on Apple hardware...'
