This one should be CLOSED INVALID as it is not a Wine bug.
It is a bug in nVIDIA drivers which had been reported and discussed here:
http://www.nvnews.net/vbulletin/showthread.php?t=163438
Actual problem is that nVIDIA allows to set swap_interval to be 0 no matter the
value of nvcontrol attribute 'SyncToVBlank' and/or the value of
__GL_SYNC_TO_VBLANK variable.
It seems that currently nVIDIA driver only sets internal default value for
swap_interval to "1" and it resets to "0" as soon as app creates d3d context
with D3DPRESENT_INTERVAL_IMMEDIATE flag.
