Hey, i'm using Linux as well. I'm running tdm on my laptop with Ubuntu 14.04. (32 bit) Intel Pentium CPU P6200 @ 2.13GHz × 2 1,8 GiB RAM Intel Ironlake Mobile x86/MMX/SSE2 The performance is far from perfect. In normal indoor areas i get around 20 fps, which is ok for me, but on outdoor areas or if there are any AIs around it keeps around 7 fps, which quite sucks I can also start tdm with wine, but then when i try to load a mission the loading screen freezes. It would be interesting to know your system data as well for comparing to see if the low fps is a linux related problem or just because my system sucks (more probable).
