Whenever I’m moving the POV around, pan, tilt, and zoom work fine, and Sketchup is running without any hiccups at 60fps the whole time. After a minute or so of moving around however, those three crawl to a halt. I can still draw, move, and alter contents and render almost instantly, but moving the view becomes almost impossible. I mash Ctrl and Shift in combinations sometimes it goes back to its normal movement speed, but most times I have to just save my work and restart SU.
How can I keep a consistent pan, tilt, and zoom speed?
