All console versions of Arkham Knight run at 30fps by default. Framerate for the PC version cannot be capped manually from the .ini files, but there is an in-game limiter that can cap fps to 30, 60, or 90.
Zips behave differently at different framerates, however the speedrun is done at 30fps for all versions.
All glitches are possible on all versions, except for rail zips, which are PC exclusive and are not used for anything in the run anyway. Therefore, the route is identical on all versions.
Gliding is significantly easier while using keyboard and mouse, and offers greater precision than is available with a controller. Though, all glides can be done on a controller.
Proper divebombing will let you gain height, if done correctly, you can keep gaining height infinitely. In theory, this should be easy to do, but in practice it is much harder to pull off, especially on a controller.
Gliding towards a level will auto-adjust and boost Batman's height (This is more noticable while OoB), making it very useful in case you lose too much height and need to recover.
Some Extra Notes:
- Holding the aim button while gliding will move the camera up.
- Falling is faster than divebombing.
If you cancel the animation of picking up the neutralizing agents you can run while holding them only when using keyboard/mouse. On controller you just walk a little faster (If you try to run, the canister explodes).
After Gordon gets in the batmobile Alfred will give you an analysis of the Arkham Knight's forces, his dialogue can only be skipped on keyboard.
Due to the introduction of the 'Gadget Wheel', switching gadgets is slower and much less convenient on controller.
