The main problem with any game removing loading times is how will you do it? Autosplitters can work for PCs if they are correctly and accurately made, but making the boundaries of where loading begins and ends for console is a fair bit harder. This is especially true if the loading is hidden, such as loading in enemy spawns during a playable cutscene.

I do not directly know what the differences in versions would be. The first thing to check would be in 360 runs at 60 FPS. Another note is that the PC version is widely and cheaply available. Lastly, I have always felt that good runners will know what a good run is regardless of medium used to play.
