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.
