I'm going to suspect that it is you Intel i3 processor that's the fault here, but I'm honestly not sure.

We don't know the exact specs that scp cb demands, so it's mostly just guessing.

I'm using an Intel pentium dual core with an Nvidia Gefore card, and nothing happens to my pc except for the occasional fps drop (it's a 7 years old computer).

Would like you other guys to comment on here too.

My pc has

Athlon II X2 250 Regor (3.0ghz, dual-core) CPU
Nvidia Geforce 9500GT (DDR2)
2GB DDR3 RAM at 1066MHZ

And with these specs, SCP CB works at a solid 60-57 FPS.
