It happened to me too (using Wine under GNU/Linux). It disappeared after I installed the latest MESA drivers (for ATI video card) and the latest Wine. I didn't change the hdd, so I would venture to say that it is not hdd-related?

Yes GNU/Linux support for this game is a bit 'scammy' to be honest. A Wine-wrapper should not be considered as a port, else 95% of Windows software could be labeled as 'GNU/Linux support'... but anyway. This is what I am doing in order to get the latest build for this game: I installed a Windows Steam into Wine and I downloaded Xenonauts from there. HTH.

This game is basically the pro version of XCOM (enemy unknown). It is a shame that it has some very unpleasant bugs (look in the bugs subforum).

If it is just a matter of too many sprites I guess it would be easy to fix... this bug is killing me

Thanks, so that means that there are at least two possibilities to consider: 1) either your computer is much faster than mine (and this is very probable); 2) or there is some difference between our software configurations that is causing this. BTW, someone reported earlier in this thread that this issue is not unique to Wine but it appears under Windows as well. We would really need some help from the developers at this point!

Thanks for the suggestion! I have attached a savegame: this map is slower on some parts and faster on others. The worst part of all is when you center your view on the Hunter: the game becomes so slow it seems it has crashed. If you center the view on the chopper instead the speed is normal. BTW consider that my resolution is 1280x800. [ATTACH]4303[/ATTACH] slow.sav.zip slow.sav.zip

This is my screenshot too. When viewing that part of the map the game slows to a crawl. If I scroll the map elsewhere the game runs fine. I would really appreciate a fix for this issue. KevinHann reported that this problem doesn't appear in version 21 stable, perhaps you could check what was changed after that?

We have similar system specs. I agree, it seems unlikely that the problem is due to our pc's being too old, else it would be happening on every map. But the performance difference is huge, I mean like the game is running fine and smooth normally and it just drops to probably 2-3 fps on certain parts of certain maps. Thanks that's very informative. So I could try with deleting the industrial areas from Geoscape too (BTW, do you have a quick hint about which files to delete?). Do I get correctly that with version 21 stable you can play in industrial area maps without slowdowns?

Is the Xenonauts version available on GOG the latest? I am using Wine too, and in order to be sure to get the latest version of the game I installed Windows Steam in Wine and I downloaded Xenonauts from there. BTW the game runs fine on Wine 1.7.18, except for some ugly slowdowns I have reported on another thread. You might want to check which version of the driver your video card is using and which OpenGL version they support.

Thanks that's a reasonable suggestion. I will try to do that and see whether the slowdown disappears after I destroy the cars. If it doesn't, it is obviously not the cars! But is nobody else experiencing different fps depending on the map?

Thank! I tried that too (went from 1280x800 to 1024x768) but that didn't change anything. Do you think cars sprites could have anything different compared to the others? I mean, could it be possible that I only get slowdowns while cars are on screen or is that just my impression? Could it be something else that is present on urban maps only? I didn't get any slowdowns on desert or farm maps. Regards,

Update: I noticed yesterday that this slowdown seems to happen only in urban maps. In particular, it seems to me that thing slow to a crawl when there are cars on screen. If I scroll the map in such a way that cars are no longer visible, things are quick again. Is that possible? What are cars, sprites or 3D models? Thanks and regards

No MAC here, as you can see from the specs in the OP it is Ubuntu 14.04 LTS. Do you have any hidden option I could use to scale back animations/graphics? Would you have any ideas about why this huge slowdown happens only on certain maps and on certain parts of the maps? Thanks for support.

Thanks for both your replies, this slowdown happens very often to me, the last time in a map at the very start of the mission (i.e. troops still in the chopper). There were no fires around, just one building in sight, a car and a van. I have tried with the proprietary Catalyst drivers but the driver that support my video card are too old and basically they don't work with my system, they require older versions of the X server and of the kernel. I tried to force them but the system just didn't boot anymore, I finally had to rollback to open source mesa drivers. I hope there is some hidden setting to go around this issue?

Hello, I am posting here a support request that I posted on the Steam forum earlier. Hello, I am having a problem with game speed in Xenonauts. Sometimes, while in combat map, the game is very slow, e.g. the map is laggy to scroll and the soldiers move at like 3fps. The game gets basically unplayable. This only happens in certain maps and in certain parts of the map; if I move my view to another part of the map things can get smoother. Perhaps it depends on the number and type of objects on screen? Is there any fix for this? I would be happy to try to reduce graphics quality, if possible. Plese tell me if there is any configuration file I could mess with. Thanks for any help! In order to get the latest version of the game I downloaded Xenonauts using a Wine-started Steam.
