If you are concerned about vsync limiting not working then say so.
For me the vsync option in nvidia-settings has always worked. NOTE: There is two independent "Sync to VBlank" switches in nvidia-settings control panels. First one is under "X Server XVideo Settings", the second one is under "OpenGL Settings". The second one is the important one for Eve.
