Wine 4.0 introduce strange performance issue in Lara Croft the guardian of
light, in short words both audio and video seems stuttering together (ta - ta -
taa - ta) as continued micro-lagging would be present.

Due this game result unplayable.

Try with 3.21 game is totally playable.

I run a regression test and I've obtained this result:
