Up until now, I believed that all five versions of the game were similar enough. Over a little more than a month I've been looking into the game on all five platforms for the purpose of comparing them graphically, but I've in turn found differences that affect speedrunning the game I'd like to share, so I'll talk about just those and will update the guide if I find anything else. I can't reliably cover loading times because I have the PS3 and 360 copies physically and every other version digitally, but the game's autosaving makes the game hang for the same amount of time whether your game is digital or physical, as Xbox One and 360 hang for the same amount of time, despite Xbox One being digital-only.

Xbox 360/Xbox One - Probably the only two platforms that let you avoid signing in. This avoids the hanging that occurs when the game is autosaving, which occur five or six times a level and saves 66 or 99ms (3 or 4 frames) of time on average and up to 192ms in Sandstorm when you shoot the second obstacle. On 360, Showdown's scene where the bear fights the wolf slows down, taking 19 seconds to play instead of 16 seconds. This is fixed on Xbox One.

PC - Essentially graphically identical to the 360 version with 60FPS support. Autosaving should only last 16ms (1 frame) on capable hardware. This version doesn't experience the slowdown found on 360.

Wii U - No collidable objects have been removed. Autosaving normally hangs for 462 or 495ms (7 or 8 frames), hitting 693ms in the aforementioned Sandstorm autosave. This version doesn't experience the slowdown found on 360.

Playstation 3 - Some collidable objects (trees) are missing in this version. This is mostly notable in Respect Your Prey as shown here - https://imgur.com/Onxi6IE . This version hangs slightly longer while autosaving in comparison to 360. On average it's 99 or 132ms (3 or 4 frames), reaching 264ms (8 frames) in the aforementioned Sandstorm autosave. This version doesn't experience the slowdown found on 360.

Wii - Weapons in the story mode have the faster reload speed they have in the shooting gallery mode. This version also has the collidable trees missing that the PS3 version does - https://imgur.com/Onxi6IE . Autosaving normally lasts 96-128ms (depending on the framerate the game's running at), reaching 192ms in that Sandstorm autosave. This version doesn't experience the slowdown found on 360.
