I play mainly on my windows machine but since the 0.8.4 patch several graphic and performance issues have been introduced.
1) the game has a tendency to crash during the load of a map.
2) the game crashes often when the zoom option is engaged.
3) a large red box is often placed in the the center of the screen during the mission countdown. I am not certain if the box disappears later as when the mission starts the box either expands to fill the entire screen and then the game crashes OR the box stays the same size and the game crashes.
- The garage functionality seems stable but any custom skins - like purchased camouflage are displayed as corrupted.
After 45 minutes of testing I would be hard pressed to give it a score about "known not to work" as I have yet to complete a single scenario.
