I'm trying to play The Binding of Isaac on my laptop, but the game is just running too fast for me. I can slow it down if I unplug my laptop, which I believe throttles my CPU. I'd like to find some generic way to artificially slow a game down.

Questions similar to this have been asked before, but I don't want to have to load up a VM or pay money for a solution. Is there some way to slow down or throttle my CPU slightly in order to make games like this slightly easier?

I am afraid your motivation will not matter. The answer is the same to the already existing questions that tackle the very same issue. –  Bora Nov 24 '11 at 17:09

Argh, okay. They both seemed similar, but not the same as what I was asking. If the consensus is they're too similar, I'll move my answer to there instead. –  agent86 Nov 24 '11 at 18:51

I figured out what was happening when I unplugged it that effectively throttled the CPU, go to:

Control Panel -> Power Options -> Edit Plan Settings -> Change advanced power settings

Look for "Processor Power Management" and you can edit the settings from there. enter image description here

It would be nice if there was a quicker/hotkey way to do this though, as I don't like to have to keep digging back into the control panel.

You can make a seperate power profile with these settings customized, and switch profiles through the power icon in your notification area. –  Joren Nov 24 '11 at 23:35

You guessed correctly why the CPU performance changed, so I won't comment on that any further.

Historically however, there was a similar problem with older (DOS) games running too fast, because they weren't built for modern processors.
For this reason, some utilities able to throttle the CPU emerged. You can find some with a quick Google search.
Keep in mind what the webpage says, though - this approach may not be suitable for modern games and the newest processors.
