Yep, I remember the same thing happening on gta4. Most notable when you would swap your own vehicle to something in a different 'set' and suddenly you'd start seeing a totally different type of traffic.
I understand how this all relates to limited memory, the bit I dont understand is why the problem only seems to manifest in the late game. It suggests to me that less memory is available than at the start, either because something else has slowly started hogging it, or there is some kind of coding problem with memory allocation.
Also begs the question why, one the game has progressed far enough / been played long enough, loading older saves doesnt seem to make a difference.
If it was consistently occurring from the very beginning I think I'd just accept it, but that isnt the case here.
Any ideas? You seem like you know about this kind of thing.
All I could think of are precisely 2 different types of scenarios.
The first one is actually more realistic but does also kind of... falsify your statement that it first appeared later in the game.
It´s simply that people might have been focused on the Gameplay and all the "new" and "hyped" stuff that we were all waiting for.
Once GTA V came out people went ape-sh*t about it and posted 10/10 Ratings everywhere, told me how much they love the game and so on.
In general it showed me how OVERhyped that game actually was to that day. (September 16th actually...)
Then over the next two weeks people have calmed down and looked at it in a more critical way, found bugs, and for the first time began to see what the game is like for real.
So it might all have been there from Day 1 on ... and you just didn´t notice it because you were too busy hyping yourself more and more whilst the game and story built up.
The second (highly unlikely...) Scenario would confirm that there is a problem with the game's Memory Allocation - to sum it up shortly - a bug.
It could be due to overload of "dead" or unnecessary files that are mistakenly loaded onto the Ram and thus tear down the once so solid looking Performance of the Game.
It could have to do with small things... like the Logos on the Map, that usually only appear once you are close to them or even something as big as the texture-set which changes throughout the game.
Short example : That house you and Lester burnt down after the completion of that very first heist... it means that the Game will from then on "offer" the System's RAM another fileset, including the textures of the burnt down house instead of the "intact building" textures of before.
All of these things could cause a Texture- and Model-Reload Bug sooner or later in the game.
I didn´t really see that certain Problems of the game became worse over the time... so I do not really believe that there is a bug with it but as I previously stated, that it is all related to a very very low amount of memory which needs to manage so much that you could hardly imagine it to work at all.
To be honest with you guys... I am still impressed what my PS3 is able to do with well-coded Applications like GTA V... not quite sure how it still runs on a 7 year old platform, but it certainly does.
I know this doesn´t really help you guys but that´s all I can tell you with my knowledge about GTA´s Engine.
Have been modding things for GTA IV since the Day it came out on PC and before that I was busy modifying stuff for GTA : SA.
