We did a trial run at the office on 2016 and found it, as you put it, sticky as well. The same models that were fine in 2015 felt 'slower' in 2016. I found that opening some files was slower as well and thought that it might be due to the new tray system, but unfortunately, there's no real way to confirm.

I went to that setting for the nVidia graphics card, and i'm showing 'Google Sketchup' and not 'Trimble Sketchup'. Could that be the problem?

Glad it's not just me then!

I also see 'Google Sketchup' in the nVidia settings. Tried uninstalling previous versions but no change....

Anyway having tweaked some settings this doesn't seem to have improved things that I can tell.

On a related note, since playing around with the settings my SU has lost its nice straight lines, I mean they were almost flawless before, whereas now they are jagged. Despite restoring the default nVidia settings I cannot get back to my lovely crisp lines. Any expert advice on this would be most appreciated...

I feel i've opened a can of worms here!
