Every move of the mouse and the screen refreshes along will all the objects on the screen. I don't have a grid lock on or anything, nor is it file size (empty template)... i checked my video card settings and pulled them back to 60hrz... Otherwise I'm stumped as what to do.
This looks like mouse drivers or graphic card issue. Check if there is better mouse driver. Also go to 3DCONFIG>Manual tune and see if you can check the "Enable Hardware Acceleration" toggle. While there click on "Check for Updates" .
