Bezier Handles Too Slow on Motion Graph

[BrianLucas]

Hi. I don't know if it is just me or anybody here have the same problem. When I try to edit Bezier handles on the motion graph, they move like honey--too slow. They don't move at the mouse point. Any solution on this will be highly appreciated. Thanks. BTW I'm using i7 32RAM and NVIDIA GeForce GTX 1060 6GB.

Opened a pretty hefty file and was able to move the handles with ease.
(I'm using 14 pro on a Win 10 Pro 64bit, Intel i7-6700k cpu 4.00GHz, 32GBs
NVIDIA GeForce GTX 970, 20447MB total graphics memory ).
You could try turning on or off the GPU Caching under display near the time line. Under preferences Max render threads I have it set at 4.
You also may need to look at your system to see if anything is running in the background (anything using a high cpu %)
Don't know if that helps but goodluck
