Immediate crashing when entering any world since 4.0.0.3155

Hi,

With the "Hostile Encounters" update, which I'd really love to test, I cannot start any world in SE2. Upon loading screen SE2 terminates within a few seconds with "Application has crashed!" and "We are sorry for the inconvenience. See the logs for details.". It doesn't seem to be affected by which world I load, not even a new "Concordia Facility". The hotfix 4.0.0.3159 didn't solve the issue.

I had posted this issue (including the logs) via the ticket system but no reaction so far. Today I probably can tell why the game crashes and maybe other people have a similar problem:

The logs indicate a fatal exception due to unsupported AVX instructionsets:

I know that my rig is quite old. But it ran SE2 quite smoothly before. Is there a compatibility option you could think of or build in when an unavailable feature (like AVX) is 'bout to be used? I mean it worked before.
