FS-UAE may not run smoothly with G-Sync/FreeSync in some cases

[FrodeSolheim]

It is mostly related to a combination of:

• G-Sync not being enabled properly if FS-UAE's vs-sync setting is off
• FS-UAE getting confused about refresh rate if FS-UAE's vs-sync setting is on

So, may need to implement a rendering mode where FS-UAE enables v-sync in OpenGL but also only uses timers for frame rate control (not waits for buffer swap).

(Note, everything works fine with G-Sync / Linux on my computer)

Yep, it happens on my setup. But I'm using the FreeSync compatibility mode of the NVIDIA 430.14 driver (G-Sync over a FreeSync monitor). Thank you !

The upcoming FS-UAE 4.0 (master branch) should work very nicely with G-Sync and FreeSync displays!
