I agreed speeding up at the initial loading screen would result in longer loading times.
The GG speed hack in duel world speeds up at the VS screen, coin flip screen, draw phase screen, you win screen, rewards taking screen, xp receiving screen.
The pvp duel process is almost the same as the aforementioned, so I think pvp speed hack could be optimized more??!!
Actually, the GG doesn’t speeds up at those screens is the reason why I choose to have it always x3 (with GG speedhack on automatically, it takes longer to finish a pvp duel than always x3)
