I just started playing and i love the mod already, but i have some performance issues. The game gets sluggish during real-time turns, but only if there are still enemies in the sector. Turn-based works flawless. This doesn't happen in every sector and i noticed it at first when i entered Drassen Airport, so it could be related to Towns. To be fair i use an old PC and run this on Linux, but 1.13 usually runs on this without issues, even AIMNAS with those big maps.

To better describe the issue: these are like minifreezes where the mouse or the movement of a soldier stops for a moment. I notice this when i move the mouse and it makes a small jump. the PC is a singlecore AMD Sempron LE-1250 with 2.2 Ghz and 4 GB DDR2 SDRAM. So this is really legacy hardware and i don't expect too much. I just use it to run some old classics. Linux often works better with them than the new versions of Windows.
