I have a Surface Book with the i7 and dedicated GPU. The issue I am having is that...in Adobe Illustrator...I am getting elements of the interface "flickering" and performance is not what I would call snappy. This is with GPU acceleration turned on (which was on by default). When I turn off acceleration...Illustrator performs as I would expect. I would think that GPU acceleration would enhance my performance...am I doing something wrong? I know the easy solution is to run Illustrator with GPU acceleration turned off...but I bought this unit thinking the dedicated GPU was giving me something more than the standard Surface tablet.
