Fire animation crashes me

Normally I crash a lot, but when I do have the chance to play, whenever I light a fire or a furnace I crash. Now seeing as this is a big part of the game, it’s hard to play. I know how to turn off the new grass and that did help but the fire still crashed me. I was wondering if there is a console command to turn off fire animation. If you can help in any way I would be very grateful. <3

Computer Specs/Internet speed might help.

I don’t have the best internet due to where I live, but it should be able to run this. It’s always my unity crashing, and yes I HAVE looked at my unity cache. I just got a new hard drive so, no there wasn’t anything in it.

Well all I know is AMD video cards are having issues, so if you haven’t updated those drivers, there’s not much that can be done until the Devs find a fix =/
