Hello,
currently I'm using a Powercolor RX480 Red Devil GPU on Windows 10 with current drivers.
EDIT: Using 0.41 Windows Stable release
When rendering the menu without V-Sync a terrible coil whining can be heard. Using V-Sync solves this problem.
However in certain places (I could add a save) this results in a stuttering mouse movement. Disabling V-Sync again removes this problem.
Ist is hard to explain. I will try to record a video file of the problem.
Can somebody reproduces this.
The problem is visible e.g. in front of Caius Cosades house when looking in direction of the mountainside.
EDIT: Further testing shows that the stuttering seems to happen when looking into the sun

Re: Vertical Refreshment Rate Stutter
The coil whine is probably because your GPU's putting out hundreds of frames per second and doesn't like doing so (it's a fairly common problem with less intensive graphics software). The stutter is likely because V-Sync forces you to run at a framerate that is a factor of your monitor's refresh rate, so on a 60 Hz screen, you'll drop to 30, or maybe 20 FPS for a moment whenever a frame is late. If it happens that certain situations cause a performance drop, that's how they'll manifest.
Of course, it's always possible that something odd is going on to cause the performance drop in the first place...

Known and resolved, but still happens with the windows builds because they're built against the wrong version of OSG.
