Someone asked on the comments of my previous video if I could record showing the keyboard and mouse inputs to do the fling. So, I should as well post it here.
What framerate are you running at penta? At 60fps I tried for quite a while and couldn't get the boost at all, but with vsync off I can get the boost about 95% of the time. It seems the higher your framerate the higher you get boosted but I might be wrong? At 400fps I pretty much get boosted to the ceiling.
If the community is going to allow > 60fps your new glitch is 22 seconds faster than my previous best segment:
I know quite a few of the other popular FPS speedruns need high framerate for certain glitches (Half Life, Dishonored, BioShock Infinite) but at the moment I believe most people run BioShock 1 at 60fps? I can't get this glitch at all at 60fps although perhaps it's just a lot harder.
