Packfile Limit Mod

The Packfile Limit Adjuster mod is there to prevent a specific error: ERR_FIL_PACK_1. However after the Criminal Enterprises update, other errors related to this mod appeared such as unable-to-find-pattern #15 or unable-to-find-pattern #9 and the Packfile mod, originally released in 2018, was updated for the first time in July 2022. These pattern errors, which previously were rarely reported, were fixed for most users by the update.

There is only one version available. Like the heap mods, it isn't mandatory but it also should be considered such.

What are packfiles? This refers to dlcpacks, the mods we install as folders containing an archive called dlc.rpf (as mentioned in first post) as well as the dlc packs from Rockstar updates. This includes all addons for vehicles, MLOs, maps, and some Ped mods. Replace mods and xml mods are not in dlcpacks.

 This mod includes one plugin, to be installed in the game folder (root) and a configurable ini file. It will be loaded by dinput8.dll as will all asi plugins.

It is set by default, packfile_list_size = 5208. The author claims this is twice the amount of the default size in build 1493 which included After Hours for GTA 5 Online in 2018.

Once more, increasing this limit might not lead to stability gains, particularly with a PC lacking adequate RAM and VRAM or other hardware resources.

The author recommends grouping dlcpacks. This is optional and like everything else has pros and cons. The pro is obviously that grouping dlcpacks into single folders reduces the total number of packs. This applies to vehicles.

The cons are numerous: the grouping process, either manually or through a mod, requires careful attention to detail and time and can be a huge PITA. It also increases complexity when editing files in OpenIV and makes troubleshooting more challenging - in other words which vehicle in the pack is causing a crash assuming you have crashes - and you will.

For those who aren't into game dlc or GTAO, you can delete the Rockstar dlcpacks as an alternative. Backup your files first.

Of course grouping or deleting isn't a substitute for a properly configured game with the appropriate hardware. Keep in mind that modding is pushing the game beyond its recommended state.

For the curious, you can view the packfile settings in the vanilla gameconfig.xml (the one in your games folder) for your specific build. As an example, using build 2372 it is 3672. Archive is Rockstar lingo for dlcpacks, which are archives - similar to zip, rar, and 7z archives (and also OIV installers).
