Even if I was to "get a grip", do you believe this: https://www.youtube.com/watch?v=2SmDUHekjMc

is acceptable game?

Similar problems were in GTA V PC version, people hated it for it until they fixed them 6 months later.

But xbox/ps crowd were happy because they got that game over a year earlier and with not such big bugs.

Here it is different PC gamers got a better game and mostly console players are complaining.

I have played GTA 5 on PS3, PC and Xbox One. I haven’t experienced any such issues on the slightest, nor remember any widespread reports. GTA4 has optimization issues, which were never solved, but not GTA5.

They've reiterated the same promises for years and years. Stop fanboying, mate.
