I've finally re-created my bootcamp partition (it was removed by accident). Anyways now that its back, some of the initial short comings that I had forgotten about are shining through. The biggest issue I'm having is scaling, which is a glaring issue with the 5k iMac. I'm finding some apps showing up too small. I have the native resolution (5120 x 2880) and the zoom factor set to 250. This makes most things fairly adequate. I also made the cursor black and chose the largest size windows allows me too in the accessibility control panel. Any other suggestions to make windows a bit easier to use with this large monitor?
