System Information
Win 10, GTX 1070

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)

blender-2.80.0 4e9911663a windows64

Short description of error

While Gizmos are on ( like transform ) there is noticeable lag when rotating the view in a blender.

This can be noticed only when another background apps are not using hardware acceleration.
All need to be disabled to replicate, that includes chrome running WebGL or NVIDIA Experience.

How to Replicate

Run only blender app without anything in the background
enable transform gizmo
rotate the view

Try this:

I had a similar problem but it was not related to gizmos. It's just that Blender has some issues which cause nVidia GPU's to constantly start idling.

Still noticeable slowdown,
I tried other options as well,

on the other hand
if I change the active tool to the cursor that is not using the gizmo
or with gizmo, if I open chrome and some site that uses WebGL, instant speed up, without closing blender
