Alias: vsync, sync Default: 0 Description: "Video synchronization" Example: 1 Type: choice

Video sync behaviour can be configured with the "video_sync" option. The default setting is off. The available values are:

Value: 1 ("Auto") If the host refresh rate matches the game's refresh rate, emulation and video will be synchronized to the display for perfectly smooth scrolling. If not, FS-UAE will only sync buffer swap to vblank in order to remove tearing.

Value: vblank ("Buffer swap only")

Video buffer swap (but not emulation) will be synced to vblank

to remove tearing. This value is used to prevent FS-UAE from

synchronizing the emulation to the display.

Value: 0 ("Off") Video and emulation will not be synced to the display. Instead, a timer will be used to manage the emulation speed. You may see tearing on the display since buffer swaps are not synchronized to vblank either.

The previous value "full" is deprecated as of FS-UAE version 2.2.2, and it will now behave as auto. See [assume_refresh_rate] if you need to force vsync.
