A person I follow did this and I was wondering if this was known about. Apparently, he scoured the net and couldn't find anything about it, so I thought it might be a good idea to ask, just in case it's actually not known about/undocumented

Now, HOPEFULLY many of you are aware of this, but if you aren't, you will be now. PC Disc runs at a faster speed, or has a higher capped speed than the other versions EXCEPT during cutscenes. It's cap is 63 frames per second which is about a 5% increase in speed. Just to be clear, if the game adds an extra 3 frames per second, after 20 seconds, the person will gain 1 extra second off of any of the other versions. Obviously, you'd need a damn good PC to keep the framerate constant enough to do that, but this can factor in for about an entire minute in Sonic's Story alone. Possibly even more.

For a clearer picture of how much is affected by this, here's a comparison between a run I did on console versus one of CJ's older runs (where we had the same time in a level):

Now, CJ's game doesn't run at a constant 62 frames per second. I want to make that completely clear. Most people's PCs would run the game between 60 and 63 FPS most of the time, with some lag spikes here and there. Now, there is a problem with this, or it impedes on something I've wanted to happen for a while... Switching over to RTA without loads. Even with this, PC disc would have at least a minute of advantages, and people with the faster PCs would reign supreme anyways.

So... What? You want to know what this means? Well... Not very much, really. Separating the versions would be stupid and kill competition/motivation for competition and removing PC disc in general would pretty much be even worse. The only proposal is a mod for PC disc to have a continuous timer in the HUB world that doesn't count cutscenes, results screens, and loading screens. Then you could just manually count everything in the other versions for RTA without loads and it'd be very accurate. However, not sure if that's possible, or even worth doing anyways, so... Yeah...
