In 4.6, I could see a difference between 2x and hq2x; when changing in the OSD menu. After updating to 4.7, changes to this seem to do nothing. I had it set to 2x, so my assumption is that hq2x is not being applied when changed? Though it could be the other way.
Restarting also doesn't seem to result in a change, though it would be harder to tell without switching.
Ok, this was user error. I had changed it from Force VGA to Cable Select, and apparently you can't change the upscaling in that scenario. Changing back to Force VGA, I can change methods as normal.
