Short description of error
I have a new Surface Laptop 3 with an i7-1065G7 CPU, 16GB, Windows 10 Pro and the Viewport in Blender 2.81 is lagging the whole time. Of course this isn’t a workstation for Blender and I’m only use it for small things and lectures , but Blender 2.79b is running smoothly and much faster.
In my opinion this is very relevant for the project. Blender should support the new basic Intel graphics which is installed on many laptops. And not everybody does high end rendering. Me for example doing real time graphics and 3D printing.
