I am not sure I have posted this before but I did a search on my post on wordpress mobile app but I got no matches so here it is. I have bought teamviewer 8 a long time ago and at the start while I was using teamviewer 8 I found the connection is quite responsive after maybe like the implementation of windows 7 I find that teamviewer 8 is no longer so responsive. Maybe upgrading to a new version would be good but I find upgrading pretty pricey.
