I also crash when i join Escape from Stratis or the headhunters mission :/

No crash when i create the server myself (Escape from stratis)

I had it to several times but its more randomly for me that sure thing, once my game crash when i want to join 404 wasteland and other time it joins normally, once game crash when i join any server + standard alpha missions and other time i join with no problem

I have been able to connect to various Wasteland mod servers. I just wait after i click the ok button after you choose your character. Before i just would alt tab and i think that that made my client crash.

EDIT: I did mix with with my graphic cards core clock so try tune it down a bit.

We need dxdiag and files from this folder for solve your problem. C:\Users\<Name>\AppData\Local\Arma 3 Alpha\

Can you upload somewhere in winrar package please?
When package will be smaller than 5,000k, so you can attach here. Thank you.
