Rhino response time

I’ve been using Rhino for years now. I’m running the latest version 7 on Win10. Recently, an odd performance issue has come up. It’s almost like Rhino loses focus or something. When I roll my mouse wheel to zoom in or out, it takes a second. Then once it has done that I can zoom in or out fast like it used to. If I say I want a linear dimension, it takes a second for the cursor to change to pick the first point. Once it does, it goes like it used to. What could have changed? I don’t see this behavior in any of my other programs.

Hi Joe - please run the SystemInfo command in Rhino and post the results here.

Hm - nothing jumps out at me there… video drivers could use an update but I doubt that is the problem. Does the problem occur in any file ?
Does closing and restarting the Rhino session do anything useful?
Is the Properties panel open an in view when the lag occurs, and if so does it help to close Properties?

It’s a bit maddening. I think it occurs in any file, but I haven’t checked some really old ones. It seems as though things work properly on first opening Rhino, then it starts up and keeps up. The problem isn’t consistent and it is not only response to mouse clicks but to keyboard input as well. Seems to get worse the longer I work.
