It shouldn't make a difference in speeds..though its easy enough to check.

EDIT: yep, that's a bug. I used Turbo to slow my machine down, and I replicated what's happening to you.

It looks like game days tick every 10 seconds, regardless of how slow the on-screen action is going. So if your hardware can't keep things running smoothly, you'll effectively have less time to complete missions..
