Does anyone else have issues with Napoleonic Wars (but not Native) on Linux? The game runs smoothly no matter my settings, for a while, then seemingly randomly drops my FPS to 10 for about 20 seconds, then it zips along again, only to do it again a few minutes later. It seems it may be happening whenever pieces of buildings are destroyed/there's lots of smoke, but it doesn't change FPS whether I'm looking at it or not.

It doesn't matter whether it's the GOG version, Steam version, or even a Windows version run through wine, it happens to all.

I'm running Manjaro with an Intel Graphics/nVidia GT540m setup with bumblebee, and it doesn't seem to matter whether I run it with the CPU graphics or the GPU, nor does it matter which drivers I have installed.

I played over 100 hours on Windows without issue, so it shouldn't be a hardware problem

Any ideas?

Reading over what I just wrote it would seem the problem lies with my Linux setup somehow, but I have no idea what could be up. Issue with all versions of the drivers?
