modifying GTA 5 allows players to import almost any vehicle imaginable, from hypercars and muscle cars to bikes and trucks. However, the base game has a limit on how many "add-on" vehicles can be loaded at once. Exceed this limit, and the game will crash on startup. This is where the comes in.
The "Game Config" mod is a modified version of the standard gameconfig.xml file found within Grand Theft Auto V. This file controls various internal limits for the game engine, such as how many vehicles can be loaded into memory, how many ped models can exist, and how the game handles resource pooling.
Not all gameconfig files are equal. The “top” or most-endorsed version usually includes recent patches for the latest GTA V game version (1.0.3028.0 as of 2025) and compatibility with other essential mods like PackfileLimitAdjuster and HeapAdjuster .
