 Description   

V-Sync does not retain settings between sessions in window mode.

Once V-Sync = TRUE in client is set, Minecraft will automatically apply. When the game is closed, and later re-opened, Minecraft will start without applying V-Sync. However, V-Sync will still show as 'true' on the video settings screen.

If the user toggles the setting, or switches to Full Screen and back. V-Sync will apply again, until the game is later closed and reopened.

Confirmed user has proper permissions to write to options.txt, Value of true is also being saved.

Setting Vsync as True in options.txt and opening Minecraft for Window mode has the same effect.

This affects existing worlds, and newly created 1.4 worlds.

Tried on a second Vista64 PC. Problem persists.

If Minecraft is set to use Full Screen, then V-Sync will automatic apply once started, if the value is set to true. This only appears to affect the default window mode option.

Confirmed with all versions from 1.5.2 to 13w18c

Please update affected versions. Thank you.

Confirmed with 1.4.7, 1.5 and 1.5.1.

After looking at the code (Minecraft.java) and testing it out I have found that the VSync setting only gets applied at start-up if Fullscreen mode is enabled. The code to enable VSync at start-up is only in the toggleFullscreen() method.

It would be great if VSync could also get applied when not in Fullscreen mode at start-up.

Confirmed (still in 13w02a),
Need to get this voted up.

Comment by omtothenom [ 07/Jan/13 ]

Fixed in 13w01a, although now I can't seem to turn it off.

EDIT: Actually, scratch that: Bug still persists in 13w01a.

Affects full-screen mode, too. Toggling the option to “On” and “Off” again fixes this behavior. Never noticed that before version 1.4.6

See MC-5243

Comment by Ois [ 30/Nov/12 ]

Yep, still present in 1.4.4 and 1.4.5.

I've updated the ticket.

Comment by Tails [ 30/Nov/12 ]

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Same problem on Mac OS X 10.8.
