Jokun, I've been playing vex 4 for 3+ years and only recently I tried speedrunning again just to release that my game was running faster than previously. The runner won't be using different hardware (purposely) instead it is a glitch with the newer version of the game, I guess. it is an interesting problem as don't know how to prevent it and maybe that is why they are allowing the runs. It does beg the question about where they draw the line with glitches in the speedrun, because there is way to beat acts in negative time with a glitch.
