PerformanceMaximizer BETA v1.0

IMPORTANT DISCLAIMER: This plugin is brand new and is my first creation. It works surprisingly well, but i do not own a standalone enterprise e-mail address or a discord server. All inquiries may be re-directed to my discord DMs (see below).

Description

PerformanceMaximizer is the lightweight and automatic performance ASI plugin I designed for GTA V. PerformanceMaximizer monitors the game's frame rate and automatically adjusts ambient traffic and pedestrian density when frame drops are detected which helps a lot with maintaining smoother gameplay during demanding scenarios.

How it works

When running heavy mod packs or high-density traffic/pedestrian setups, FPS drops and crashes are frequent. PerformanceMaximizer tracks your average frame rate and scales down game world complexity (peds, vehicles, etc.) when your system struggles to keep up. It is based on a tracking system that determines whether your game is stable or not by analyzing the frame rate. The plugin works by monitoring your frame rate and comparing it against thresholds defined in your configuration file:

* State Monitoring: The plugin tracks FPS over a rolling average to avoid constant state switches (performance states listed below).

* Performance States:

-Normal: Default game behavior, density isn't changed.

-Moderate: Triggered when performance dips, slightly lowers traffic and pedestrian density to achieve stability.

-Critical: Triggered during severe performance drops, drastically reduces world density and performs targeted "purges" of distant ambient vehicles and peds to reduce CPU workload and RAM usage.

DISCLAIMER:

Compatible with most SHV/GTA builds, provided that your SHV (Script Hook V) and game build versions (e.g. v3788) match. Tested on build 3788 with a heavily modded LSPDFR setup.

I AM NOT RESPONSIBLE FOR ANY KIND OF HARDWARE OR SOFTWARE RELATED ISSUES. THIS PLUGIN IS PROVIDED "AS IS" WITHOUT ANY KIND OF WARRANTY.

PerformanceMaximizer does not increase GPU performance or optimize third-party mods. It focuses on dynamically reducing game world complexity when sustained FPS drops occur, which stabilizes and slightly increases frame rates, no matter what mods you're running. It also helps avoid memory related game crashes. DM me if compatibility issues with other mods are found (see above).

On lightly modded setups, you may see little or no improvement. This plugin is primarily designed for heavily modded setups where ambient entities contribute significantly to performance drops.

AI was used in the making of the logo and certain parts of the script.

Requirements:

Script Hook V by Alexander Blade - https://www.dev-c.com/gtav/scripthookv/

ASI loader included with Script Hook V (dinput8.dll)

Installation:

Simply drag and drop PerformanceMaximizer.asi and PerformanceMaximizer.ini in your main GTA V directory (e.g. where GTA5.exe is located).
Consult the .ini file and configure it to your needs.

Recommended for heavily modded setups:

A modified gameconfig.xml, preferably one labeled for heavy modding.

HeapAdjuster - https://www.gta5-mods.com/tools/heapadjuster

Packfile Limit Adjuster - https://www.gta5-mods.com/tools/packfile-limit-adjuster

Resource Adjuster - https://www.gta5-mods.com/tools/resource-adjuster (ONLY IF YOU'RE HAVING TEXTURE LOSS PROBLEMS)

fwBoxStreamerVariable and decals limit patch - https://www.gta5-mods.com/tools/ymap-load-list-extent-limit-fix-fwboxstreamervariable-patch

Little disclaimer for the recommended mods section: Those mods are not needed for PerformanceMaximizer to work properly (except gameconfig.xml which helps with ped and vehicle culling but is still not required), they just help with the general optimization of GTA V, especially with heavily modded setups.

Hi! Thanks for the report. Peds or your character freezing walking in place is an aggressive symptom of the plugin working.

When FPS drops, the script lowers density and performs purges entities. In BETA v1.0, these density changes and purges happen instantly. The engine sometimes glitches the animation loop right before an entity is removed or while it's adjusting, which causes that temporary freeze. The high FPS you're seeing means the logic is running fast enough to glitch, which still means it's kinda working (lol).

To try to fix this, open your PerformanceMaximizer.ini and try these adjustments:

-Increase [THRESHOLDS] Critical a little. This makes the "instant purges" less frequent, triggering only during very severe drops.

-Do the same for moderate, that way the purges only happen during worse performance drops.

A future version will hopefully feature less aggressive culling (reducing density over 2 seconds instead of instantly), which should eliminate these animation glitches.

Most advanced LSPDFR users know that new mods like this tend to cause more problems than they are worth. If you are still having performance issues with a 13 year old PC game I highly recommend you consider upgrading your hardware.

It is separate and will run alongside it. PerformanceMaximizer performs purges of entities (NPC vehicles and peds) to help with performance while Resource Adjuster allocates more ressources (VRAM and RAM) to the game engine. No compatibility issues so far, both run just fine alongside each other.
