Il-2: BoS (steam) is running under Wine staging 2.4 (amd64); windows XP; CSMT: enabled

Game runs flawlessly in single and multiplayer with the exception of 2 graphical glitches:

1. depending on ingame settings there may be graphical artifacts that wash out colours under certain lighting condition - not beautiful but a minor issue gameplaywise. Unfortunately I have not yet been able to pinpoit the responsible setting. It may also be a bit of luck when starting the game. The artifacts seem to be either there or not and stay that way for the session.

2. this one is somewhat more severe. While trees, buildings, streets and vehicles are modeled at the correct height in the world the underlying terrain textures are shown at sealevel. This makes low altitude attacks and landings somewhat more challenging because you can not really judge the distance to the ground unless you are in grass rendering distance and visually has the effect of objects appearing to wander over the landscape with changing viewing angles. Even though this does definitely have impact on gameplay it is not really gamebreaking (the terrain is comparably flat anyway) and I found the visual distraction to be minor as well.

Probably would not recommend buying the game in this state but should you already own it you might want to give it a try.
