Really? When I adjust sliders in my CFM it definitely changes things... I've never noticed main menu sliders having an effect on my CFM. (except for display settings, like the "skinny" pick a play window, since that can't be adjusted in CFM)
But I only play offline CFM, and I've always left everything at default in my main menu, and I adjust sliders within my CFM and it definitely has an impact. Like I have increased a few penalties within CFM (default in MM) and only after I increased them did they start happening. (again, I changed nothing in the MM)
Can you explain a little more than you do in your OP exactly which main menu settings affect gameplay in a CFM? In the OP you say MM injury is actually the "CPU try harder" slider yet you recommend it be set very low at 10? So you don't want the CPU to try hard? Is that the only slider from the MM that affects CFM?
I'm confused, lol.
