how to set arma 3 to use all 8 cores? I have AMD FX-8350 8-Core Processor. how to set arma 3 to use all 8 cores? and will it affect my cpu?

In the launch parameters -cpuCount=8 or if you like to use the Arma's own launcher that I recommend you can find that same thing there. Arma likely sets up that by itself already so you won't see any increase anywhere.

I would make sure all your CPUs are unparked.

If your using Win7 then you need to install hot fix patches from microsoft. The design of amd 6/8 cores resulted in them being parked even when threads were assigned. Microsoft claims an avg 10% performance boost when it comes to games. If your using Win8 the issue was resolved and ignore this post

Both patch DLs and install instructions on this site

is it dangerous to unpark your cores? is there anything wrong at all to unpark your cores?

Only dangerous if you don't have the power supply to support it:
