Thank you for bringing this to linux.
I just bought this game a few weeks ago and have been fiddling around with wine. That was a bit disappointing, because something in my system seems to make it crash, randomly but reliable. Its really stressful for the team when a lot of money and some costly weapons are lost in round 9.
With the Linux version I don't crash any more and am actually useful for the team.
Framerates are ok and the whole thing is overall doing well so far. However I noticed some small issues, some of which have already been mentioned here, so I can confirm them.
- At the end of each round, when the trader closes her shop, there's a small framerate drop. It may be when the game loads the soundfile or the door closing. It just stops for a second and then continues. It's not a big deal, but noticeable and reproducible. It's probably the door, because I can not remember noticing such framerate drops during a wave (or if there were framerate drops, I'm unable to definitely correlate the hiccup with the trader).
- Sometimes when tabbing out of the window (playing in windowed mode) the mouse does not get caught correctly in the game window and behaves erratically. It suddenly resets the view to pointing at the ceiling or randomly rotates the view. It looks like "dancing" to other players.
Tabbing out and back in again sometimes fixes this issue. Actually clicking on the window when going back to the game might help (as opposed to not clicking and just alt+tabbing).
- I can also confirm, that perks are not leveling. Kills and damage are being counted during the match, but when the map changes they are reset. So the perks will not level at all.
Thank you again for porting KF. Let me know if I can provide you with more specific details on these issues.
