1.0.877.1 is not a patch. It is a .
Rockstar Games, in their infinite wisdom, built Los Santos with a budget. They said, "The streets can hold only 200 cars at once. The sky can hold only 10 helicopters. The pedestrian AI can only track 50 souls at a time." These are hard limits, baked into the binary like concrete.
Without these companions, the 1.0.877.1 gameconfig will work, but you will hit "Heap" errors after installing ~50 mods.
The 1.0.877.1 gameconfig solved this by significantly increasing these internal limits. By modifying the XML values within the file, developers were able to tell the game engine to allocate more system RAM and VRAM to handle additional data. This specific version was tailored to match the 1.0.877.1 patch architecture, ensuring that the offsets and memory addresses remained compatible with the executable file of that era. It focused on increasing the "Ped" and "Vehicle" limits, which are the most common bottlenecks for modders. 1.0.877.1 gameconfig

Vanilla GTA V supports roughly 300 vehicle models. The 1.0.877.1 gameconfig typically raises this limit to . This allows you to install massive car packs (e.g., "Realistic Vehicle Pack" or "LSPD Fleet") without the game refusing to load new models.

The 1.0.877.1 GameConfig has several use cases, including:
The primary function of the gameconfig file is to manage the memory allocation and limits for various game engine elements. In the standard, unmodded version of GTA V, Rockstar Games sets these limits to accommodate the base game’s assets efficiently. However, when users begin adding "Add-On" content—most notably car packs and high-resolution textures—the game often exceeds these hard-coded boundaries. Before the widespread adoption of custom gameconfigs like the 1.0.877.1 version, users would frequently experience crashes to the desktop during the loading screen or shortly after spawning a modded vehicle. This occurred because the engine reached its "heap" limit, or the maximum number of simultaneous assets it was allowed to track.
