@Willief23 After using that gameconfig there is 100% an improvement, although, with a few Add-On cars spawned in, the map loads slower in the distance which isn't too bad, but certain cars and always the same ones loose their interior texture and sometimes things like the engine bay and exhausts? I guess I will just have to stick to one car at a time lol.
Really strange, I haven't had this problem in the past.
Thanks again though helped a lot!

@EDGeNA Hahahah, yeah i didn't think it would be

@Willief23 Yeah definitely, you have described my issue perfectly there! roads, building and their textures blinking on and off, and even some areas of the map completely disappearing. I will definitely try your gameconfig, and yeah I tend to stay away from map mods anyway, I have nothing like LA roads on/installed.
Thanks a lot for your help I'll try the gameconfig and if all goes well ill let you know!

@EDGeNA I thought it could have been RAM too, but I have 64GB DDR4 @ 3200Mhz, surely that is not the problem? And yeah okay, I understand they have better textures and will be more demanding. Although I don't believe this issue used to be a problem, I think it has occurred since one of the latest patches?
anyway thanks for your help much appreciated!

After spawning in 5 or so added cars, the world's texture goes, only some of the cars (added/modded) loose their interior texture and the map loads slow with it constantly disappearing and reappearing?
All the cars I have added are Add-on, I have no graphics mods or any other mods and my PC specs are more than enough to handle GTA?
Does anyone have an idea why I am getting this issue?
Thanks
