Bug Description
I've installed NVIDIA-Prime v0.5 on Ubuntu 14.04 with all required dependencies, on a Clevo 355STQ with a 765m.
My issue is that whilst the new switching feature works very well, it still produces an extremely noticable amount of visual stuttering. In graphical and applications and games I can produce very large frames-per-second numbers yet the amount of visual tear makes the program unusable. Vsync/Sync to Vblank/
Has anyone else had this issue or found a fix?

Unfortunately this is a current limitation (to be fixed in the future) also mentioned in NVIDIA's documentation:
"There is no synchronization between the images rendered by the NVIDIA GPU and the output device. This means that the output device can start reading the next frame of video while it is still being updated, producing a graphical artifact known as “tearing”. Tearing is currently expected due to limitations in the design of the X.Org X server."
