Take this with a grain of salt, as I am a fresh Linux user. I have an AMD card and had the same issue. Everything was blurry in games and "out of sync" as I will describe it. I found somewhere somebody suggesting running these commands.
sudo apt-add-repository ppa:eek:ibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade
I actually did this and then later played Torchlight II. Whatever this did made a big difference as things were way more smooth and less blurry/out of sync. Thus, I believe this task may help you. I just don't know exactly it does.
Interestingly, I just tried to run it again as a test and now I get
ERROR: '~eek' user or team does not exist.
So maybe just running
sudo apt-get update
sudo apt-get dist-upgrade
is what did the trick for me.
Hopefully someone with more experience will have some drivers for you.
