what am I doing wrong?
Did you read what I wrote?
In SU2016 and earlier versions you could turn off hardware acceleration which would make the CPU do the rendering. With SU2017, that is no longer an option. The rendering is done by the GPU. That means the GPU must be sufficient.
Again, what graphics card? What driver version?
There have also been many user reports of delays related to some files Microsoft pushed in automatic updates. Removing those fixed the problem. First, make sure your graphics drivers are up to date and that your graphics card can support OpenGL 3.0 or higher.
