Just bought the game but on my laptop with windows 8.1 it crashes after trying to start the game via the launcher, tried all compatibility modes, and running it as administrator. but no luck.

Intel® i3 4030
8GB RAm
Intel® HD Graphics 4400

8.1 isn't the issue because I've played it since the first build. Check the Steam forums maybe? Does it say anything at all when it crashes?

Well i just retried again and even though i already tried normal graphics with V-sync enabled, it worked this time. dont really know what the problem was. because without v-sync it just crashes.

Wow ok, you'd think it would crash the other way around. Must be a compatibility with your integrated graphics I suppose.
