no that setting (Sync to HDMI (my TV)) does nothing for me either but my TV is lcd the same for my monitor.
I cant (really dont want to) go back to windows.
I cant try removing the nvidia and using the on-board , well i could but it cost me £££.
I cant keep swapping the vid leads between the nvidia and the onboard just so i can play games on windows
It was posts like this that make me want to just dump kde and look at others (although cinnamon was tearing to when i tested it)
OK, so i just installed "LM 17 MATE" on on a spare partition. Wow, what a difference! I am running Compiz and Nvidia 331 driver and everything is peachy! The system is extremely responsive and I have ZERO screen tearing. There are some issues with the current version of Compiz in the repo's (3D windows don't work properly and some animations fail) but most of the good stuff works great. I forgot just how good Compiz was... please God don't let it die...
So I guess I'm leaving the KDE camp for now. Gonna check out LM 17 XFCE next and see how well that behaves with Compiz. I will report back with my feeble opinion sometime soon, if only to bring some sort of closure to my recent grumblings!
my main comp cost me over 1k and i get a better TV output from a cheep tablet
(when using linux).
