Dishonored 2's Pro support is a total joke. Easily the worst example of it by a wide margin. One of the downsides of individual developer support, some are going to blow it big time.
I thought it looked stunning on my 4K display, and ran super smooth running on the Pro. I mean, it's all anecdotal here, so it would be interesting to find out what exactly was enhanced, but it hit the two big points for me so I can't say I'm not satisfied.
