GTA 3 Developer Explained Why He Had to Slow Players Down
Vice City, the following title in the series, didn’t have the same issue as the code was improved, providing better compression of models and textures: “Smarter code that would load the detailed versions of buildings only if the player was not flying.”
Then San Andreas arrived in even better shape. The abundance of low-detail countryside between parts of the city helped the streaming a lot. It had its own peculiarities, though. You could see small planes flying (or crashing) around to perform a fly-by. Vermeij explained their existence as well along with how mirrors worked in SA. We might have seen more GTA secrets in Vermeij’s blog, but Rockstar didn’t like him talking about the development there, so X/Twitter is our only chance to know more now.
