Okay, so you're having a problem with ARMA 3 crashes? Well I looked into it for a while and I noticed on every forum, website or what ever 90% of the users experiencing this problem were actually using Windows 8, now the crashes that come with using Windows 8 are your game crashes if you going into options - video in game via main menu, well everywhere really. Another crash is caused by going into gear normally, vehicle gear, weapon crates and well pretty much all gear options that open the inventory.
*How To Fix, I Suggest Reading Above.*
1) Go to your game library via steam.
2) Right click on ARMA 3 Alpha.
3) Go to properties and then click on the Betas tab.
4) Select Development build and then the close button at the bottom of the window.
5) It should automatically download a 150 Mb. update. In the server screen, search servers that run the development build
