There's a mod linked in that thread which will help. We don't' yet know if the devs will fix it, as noted Intel video systems are not supported hardware for this game.

The game and its patches are not tested on unsupported hardware, of course. So essentially it was luck that it ran okay before 1.29; clearly there is some change in 1.29 that triggered this problem (on Macs only BTW).

Sorry that happened to you! But at least you know where you stand now.

The other poster here says "your specs are out of date and no longer supported now", which is untrue - the game has NEVER been supported on Macs with Intel video systems; it is just that by happy accident it used to run adequately on them, but no longer did in 1.29.

That said, this thread is over 3 years old and I can't say we're seeing other such reports now, so this situation may have been ameliorated by another happy accident. Do let us know if you give it a try now.
