Resolution Issue in Bootcamp (New rMBP 2015)

I just installed Windows 8.1 using Bootcamp on my 2015 rMBP (2.5 16 370x) All went smoothly other than the fact that I can't change the resolution in Windows. it is currently set at 2880 x 1800 with no option to change it (see image). This has created two problems:

1) everything is really small, though I was able to make things better by changing the scaling

2) This resolution lock has also extended into a couple of games I installed. This is the main issue as it is making things rather choppy and unplayable..

What can I do to fix this? I tried going on AMD's site to update the drivers but am coming up with no results for the 370x? Do I just have to wait for an update to come along? Any help would be greatly appreciated!

Do you have the AMD Catalyst Control Panel installed? Are there any unknown devices in Device Manager?

Does Device Manager show the 370x as the Display Adapter in Device Manager?

Please use System requirements to install Windows on your Mac via Boot Camp - Apple Support to download BC drivers for you specific Mac. If it says BCA, use BCA to download software and then either System requirements to install Windows on your Mac via Boot Camp - Apple Support or Boot Camp: Solve Windows support software installation problems.

The newer systems use BCA as shown.

You should use BCA as well.

Bumping this thread : I am having the exact same issues as the OP and BCA won't fix the issue, nor will drivers from AMD's website. Super confused here... My Windows installation is perfect except for the graphics which is unusable (can't change resolutions, can't play any games).

Tried everything I could think of but no luck, anyone else still having the exact same problem? I've tried loads of combinations of installing / uninstalling the graphics drivers but it just won't recognize the AMD card on the bootcamp partition.

I'm stumped.
