Do you have the latest nvidia drivers? Make also sure to try out the latest blender beta.

If you have the latest, can you try running blender with --debug-value 23 and see if any of the values changes drastically when you have selected the move tool.

can you try with an empty object? to see if it really comes from the tranform gizmo? also you can change your active tool to the cursor tool to verify that.

yes, when transform gizmo active - lag. scale/move/spin etc

HI, I have the same problem when gizmo is active.
Windows 10
Nvidia gtx 1060 Ti

same problem Gtx 1070
I think It is the same as T57677

it looks like card detection or acceleration problem since it exists only if nothing is using a card in the background, even opening the Nvidia experience just speeds stuff.

edit:
it is related to all gizmos not only transform, even python ones

Same here, downloaded the feb10 nightly build and the feb14 build as well, I can confirm I'm having this exact issue, anytime the gizmo is present in the view port, it slows down view port performance and creates stutters and lag. Running a quick cycles preview render once on viewport seems to help alleviate the stuttering, but it is still there.

***Edit: viewport panning/rotating stutter and lag seems to be present when a camera object is selected as well, without the transform gizmo active, though the active "click and drag" handle function of changing the camera focal length should be taken into consideration as well for this bug.
