How annoying is it to have to replay a song just cuz of silly lag it ruins the game there should be a System where if it lags it Pauses the game at the spot ur at not near a note so it does not interrupt ur gameplay
It's difficult to recover from a pause in the first place, I doubt it would be much better. Not to mention, I have no idea how you'd implement this, or even have it be lenient enough to not affect regular gameplay yet strict enough to be useful.
Sorry but I suffer from lags too. I have a MacBook mid 2010 (so ~5 years old now at the time of writing). Even though I upgraded to an SSD and twice the RAM it used to have, it still stutters from time to time. However even if it's been implemented, someone somewhere will exploit this feature for there own good. Especially if it's a feature that lets you recover from a combo break.
