A couple of things:

1. Go to the settings of Armour Crate and on Operating Mode go to GPU Settings and change the Memory Assigned to GPU setting to Auto otherwise the game won't start at all.

2. Absolutely download and install the latest gpu drivers, just in case the device hasn't done it automatically, if you want better performance.

3. Occasionally the game will crash with an "out of video memory" error but it happens randomly after long sessions at least for me.

4. Finally i also used the pagefile on the manual settings to increase the virtual memory but i don't think that helped (Google it if you still wanna try).
