Ya, that's the one.

If you don't have it installed then obviously it's a non-problem for you :-)

I don't know what GUI you're using, and I don't use one myself, so I can't answer that with any certainty. But if you run cpufreq-info, it should tell you which governor you're using. If it's "userspace", and the CPU frequency is at maximum, then you should be fine. "Performance" is *not* the same thing, IIRC. The "performance" governor will still change your frequency and might cause glitches. Then again, it might be fine for you. For example, I've seen advice to remove the kernel modules completely in order to assure that there is no throttling going on, but that hasn't been necessary for me.
