Just curious to know how STK use my hardware. I've got a strong cpu but a basic graphic card (I don't want fan in my setup). So I'm particularly interested to know if STK use all the core of the CPU or not.

When loading texture

to expand a bit on that basically, we use multiple cores in a few areas, but not as much as we could. However, even if STK used more cores that probably would not help you much because STK is usually not very CPU-intensive, the GPU is where most work is spent

the GPU is where most work is spent

Ok, I think it's the limit of my comprehension. If the GPU is solicited to much, does the cpu take over to help the gpu? Is that system dependent (I'm on GNU)?

I also want to be sure if there is any option to activate multi-core support (like in compilation), like certain soft did.

The GPU and CPU are very different piece of hardware meant to do different tasks, so when the GPU is taxed to the maximum, the CPU can't do a whole lot to help (a good GPU may have thousands of cores, whereas a good CPU has 4/8 cores, so the CPU can't help all that much)

Thanks for the details!
