The basic gist of the quicksave glitch is that everytime you quicksave the game jumps forward a little bit. I don't exactly know why that is, but every animation is sped up. NPCs move quicker, the next line of dialogue at the end of mission debriefing appears quicker, timers, like in Pavlov's house, pass quicker, and, most importantly, player movement is faster.
All you need to do is to constantly spam the quicksave button, which is rebindable. Mouse-wheel seems to work aswell.
Just comparing Sawyer's 1:18 in Pathfinder without quicksave-glitching
to a quick, sloppy attempt of mine, with quicksave-glitching
makes it pretty obvious.
Appearently it's been known that it speeds up NPC animations, but seemingly no one bothered to test if it works for player movement and things like timers.
Asked in the discord but lol discord, where does scripting fall into this? a wait script is allowed in CoD4 runs, would a similar script be allowed for quicksaving?
Manual QS spam would be a pain for SS runs and it's horrendously inconsistent in comparison to a script where you can set it to QS at the optimal frequency.
I deleted my earlier post in this topic, but someone mentioned the CoD4 script so I thought it worth bringing up again since there seems to be some precedence for allowing scripts.
Apologies, wasn't asking if it's necessary, but if it's allowed.
In my testing using a script was a lot more consistent and bearable, and demonstrably faster by quite a lot. There's also the issue of the peak performance gain from QS spam being dependant on the drive you're using, since faster spam leads to faster times, but there's a limit at which you QS too much and the game will lag, this being dependant on one's drive.
Since the script is very similar to the one used in CoD4 for the elevator glitch, I can't see any reason to ban it on grounds of being a script.
Edit: tested the above in MW2, you can QS with it but it doesn't make things go any faster as far as I can tell...at least, not by as large an amount.
