I've might've already said this, but I can't find said post; I've only played GTA Online once. I wasn't exactly fond of it, and considering I have mods installed, I'd rather not play online because...I am being a paranoid forget.
Plus, GTA 5 runs weirdly on my system. I usually start out going smooth with a perfect frame rate, and then it starts stuttering...and then eventually it'll become horrible and broken and can't load parts of the map, leaving massive voids here and there.
