For anyone running a recent Linux kernel it is possible to see the performance impact of SMP by adding 'maxcpus=1' to your kernel line on boot. This will basically give you a uniprocessor system, check it with cat /proc/cpuinfo. Then benchmark and see the results, it's not halved I can tell you that. Maybe 25% slower on my E8200 at OMG. Much of this is down to graphics driver and other system laod rather than the game itself.

Someone clarified me about that on IRC, a post here confused me. Glad it has this in some places and my 4-core 8-thread CPU makes some use of it

Amdahl's law at work? Just because an application can use multiple cores, doesn't mean it scales linearly performance-wise with increasing amount of them.

Hmm, I also got Bulldozer, and I had FPS drops on normal settings when I tried Xonotic on it...
