I'm getting performance drops even with my pc on TS4, sometimes i get tearing on the screen, othertimes it stutters a little. My computer can run TS4 two times over quite easily and GTA 5 with plenty to spare, so it isn't an issue of hardware and my software is more or less up to date. It might be assets loading and unloading but it could also be a lack of overall polish to the product in the form of optimising the games graphics, like they got most of the way and decided to release it like that and then move on entirely to other tasks.
i don't really know if there is truth to that or not.
