GTA Online can easily consume over 12GB of RAM; upgrading to 16GB in a dual-channel configuration is considered "non-negotiable" for a stutter-free experience.

This is the largest performance killer. Disabling MSAA entirely and using FXAA instead can provide a massive FPS boost (up to 30-40%) with minimal visual loss.

Found in Advanced Graphics, setting this to 0.500 or 0.667 lowers the internal render resolution while keeping the UI sharp, providing a major performance boost for weak GPUs.

Moving from "Ultra" to "High" or "Normal" can reclaim roughly 10-20 FPS , particularly when driving through Blaine County.

Create a commandline.txt file in your main GTA 5 folder to add parameters like -disableHyperthreading (for older CPUs) or -FrameQueueLimit 1 to reduce input lag.

Enable Game Mode and Hardware-Accelerated GPU Scheduling in Windows settings to prioritize the game's access to hardware resources.

Boosting your FPS in GTA 5 for 2023 requires a mix of aggressive in-game setting tweaks and specific system-level optimizations to stabilize the aging but demanding engine. While GTA 5 is generally well-optimized, it can encounter severe stuttering if pushed beyond hardware limits or if the engine exceeds its "engine cap" of approximately , where it becomes unstable.

Installing the game on an SSD is highly recommended to improve asset streaming and reduce micro-stutters while driving fast.
