Happened to me all the time on PS3, missing out on recording those momentsUnfortunately, no. It happened when I was playing the 360 version and I had no recording capability. I've been thinking about trying to recreate it on the new version, but I'm guessing it was a lightning in a bottle type thing.
Has the online been fixed at all since release? I wasn't able to enjoy GTAV online on Xbox One at all when it first released. My strategy since then has been to pretend it doesn't exist.
Can't comment on XB1 but I play PS4 GTAO and I'll get some laggy sessions here and there. Seems like it's caused by individual players or just temporary spikes. Pretty playable imo. Fair amount on my FL are playing online.
