Yeah I have Win10 x64, for the most part my experience has been positive but then again it's on an offline machine and I have a fallback Win7 install. It's looking pretty grim for Backburner to be honest, now I have to bug Autodesk and see if that will change. I guess it's going to be bat files while I research alternatives. I'm even torn between Maya 2015 and 2016, some of the new features are great (color management alone is a treat) but I'm not exactly thrilled with how much it's been crashing when using Hypershade's look dev feature so I had to cut that. Unified sampling so far is just painfully slow so I let that go too. Poking around the new stuff to see what's worth it is maddening and I'm ranting now, great lol.
