Hello! We have done a lot of testing over the years and with new tools and more data from multiple consoles and newer emulation versions we have found that IGT is very stable overall. I have retimed all the runs on the board I am pretty sure. This has the largest impact on Story Mode in that scroll management in both NG and NG+ will be more chill and you can equip mid stage without losing a bunch of time. This should allow for some new strategies as well. Lag frames are compensated by the games IGT so if you lag a lot due to inferior hardware or degradation it should be compensated a lot. Lagging on purpose has some time saving qualities in places, but its fairly insignificant and only matters in places where you arent moving but rather waiting on audio timers. This occurs in a few spots but its really sparse overall and often lagging while in these sections arent very possible.
