What play speed do you use most often?

I play a lot of challenges so I'm usually speeding through just so I can advance a little further into the challenge that day. I pause a lot for screenshots. Honestly, I have a bad habit of using Ultra speed. It's really bad for simulation lag. FYI: Simulation lag as nothing to do with game requirements (all though not meeting them I'm sure you're going to encounter more issues). If you're hardly ever fast forwarding then you're likely to never encounter it.
