I gave up on playing GTA:O because everything took so long to load, having never spent a dime. I have to imagine there is so much lost revenue because of this bug; I hate to be harsh but it is truly an embarrassment that someone external to R* debugged and fixed this before they did (given they had 6 years!).
Load times is absolutely the primary reason I quit playing.
Same here, being slow as molasses really spoiled the game for me. I wonder if the same software quality caused other unnecessary in-game loading times. I felt that time spent playing GTA:O was about 60% waiting in lobby/playing, and the remaining 40% actual play time. Same with RDR2 by the way.
