Previously it ran unacceptably but it was possible to play. Now it completely locks up for ~1-2 seconds every 10 seconds. This is the case for MULTIPLE people I play with, but some are having much more mild issues.
Fiddling with frame limits, smoothing, vsync, etc does not change anything.
The game is literally (not figuratively) unplayable.
