Cannot select GPU scaling options

[boris.kempynck]

Hey

For some reason I cannot select any gpu scaling options. I can turn GPU scaling on/off but I cannot select the desired scaling option. Is there any way I can change this?
Here is how it looks like exactly: https://gyazo.com/7177a98e9b1851667e1ab1fd445c48a4
I'm on a MAC from mid 2011 running bootcamp Windows 8.1

You may want to uninstall and reinstall your drivers for your AMD device. Speaking of device, might want to pass on the SKU for your MacBook/Mac.

Can you explain me what SKU means?
