It has a habit of crashing on me randomly as soon as I fire it up and join an MP server.
Any idea what the problem is?
This has never really occurred before, but has been happening for at least a few weeks now.
EDIT: I downloaded 3.82 and it doesn't seem to crash anymore, but now shaders don't work.
Any help would be much appreciated.

This exact same thing happened to me (On my mac). My toribash has been crashing in MP servers for about 1-2 months now, and it usually stops after about 3-5 times reopening it. Later, my shaders stopped working. Except, I think I have pretty much stopped playing toribash anyway, so I don't know if the other problem has gone away yet.

Have you tried upgrading the graphics card?

I wanna see what people come up for you, maybe it'll work for me.

Well yeah, mac clients need some checking.

I'll ask hampa about this when he's around.

yea, for me, shaders do not work(i have a mac too) and my fps is alot slower than usual. it went from 31 to 24fps... :/
