GTA FPS Calculator

This tool provides a domain-focused FPS estimation model for GTA Online on PC. It translates hardware specifications, display settings, and quality presets into a credible FPS range by applying a calibrated, multi-factor formula. It supports common game resolutions, refresh rates, and graphic presets, enabling quick comparison of configurations without real-time benchmarking.
The model combines CPU and GPU indices, available VRAM, and resolution-driven scaling, applying preset multipliers, anti-aliasing penalties, and optional features like ray tracing to adjust FPS expectations. Outputs include a numeric FPS estimate and a recommended settings profile, with flags indicating potential bottlenecks (CPU, GPU, VRAM).
Inputs are structured as fields: cpu_model, gpu_model, system_ram_gb, vram_gb, resolution, refresh_rate_hz, graphics_preset, and optional advanced controls (msaa, rt, frame_cap). Outputs include fps_estimate and suggested presets. The tool uses a transparent, rule-based algorithm so builders can audit the math and reproduce results across similar hardware families.
Use cases include planning upgrades, validating purchase choices, and optimizing GTA Online play for consistent frame rates. Distinguishing value comes from explicit GTA-friendly scaling rules, documented input validation, and the ability to export presets for reporting or benchmarking exercises. It is best used as a first-pass estimator rather than a substitute for live measurements.
