This calculator helps you estimate the potential frame rate (FPS) you might achieve in a PC game based on your hardware specifications and game settings. Frame rate, measured in Frames Per Second (FPS), is a crucial metric for a smooth and immersive gaming experience. A higher FPS generally means a smoother visual experience.
function calculateFrameRate() {
var cpuScore = parseFloat(document.getElementById("cpuScore").value);
var gpuScore = parseFloat(document.getElementById("gpuScore").value);
var ramSpeed = parseFloat(document.getElementById("ramSpeed").value);
var gamePreset = parseFloat(document.getElementById("gamePreset").value);
var resolutionMultiplier = parseFloat(document.getElementById("resolutionMultiplier").value);
var resultElement = document.getElementById("result");
resultElement.innerHTML = ""; // Clear previous results
if (isNaN(cpuScore) || isNaN(gpuScore) || isNaN(ramSpeed) || isNaN(gamePreset) || isNaN(resolutionMultiplier)) {
resultElement.innerHTML = "Please enter valid numbers for all fields.";
return;
}
// Basic formula – this is a highly simplified estimation.
// Real-world FPS depends on many more factors (game engine, specific optimizations, CPU/GPU bottlenecking, background processes, driver versions, etc.)
// This formula attempts to give a general idea by weighting components and game settings.
var cpuFactor = cpuScore / 10000; // Normalize CPU score
var gpuFactor = gpuScore / 10000; // Normalize GPU score
var ramFactor = ramSpeed / 1600; // Normalize RAM speed (assuming 1600MHz as a baseline)
// Game preset impact (higher preset means lower FPS)
var presetImpact = (6 – gamePreset) / 5; // 5=Ultra (low impact), 1=Low (high impact)
// Resolution impact (higher resolution means lower FPS)
var resolutionImpact = resolutionMultiplier * 1.5; // Higher multiplier significantly impacts FPS
// Combining factors – GPU is usually more impactful for FPS, followed by CPU. RAM has a smaller impact.
// This is a heuristic approach.
var estimatedFPS = (gpuFactor * 0.6 + cpuFactor * 0.3 + ramFactor * 0.1) * presetImpact * (1 / resolutionImpact) * 100;
// Add some randomness or a minimum baseline to make it look more dynamic, though real-world is complex.
// For simplicity, we'll cap it at a reasonable range for high-end systems.
var finalFPS = Math.max(15, Math.min(estimatedFPS, 200)); // Cap FPS between 15 and 200
resultElement.innerHTML = "Estimated Frames Per Second (FPS): " + finalFPS.toFixed(1) + "";
resultElement.innerHTML += "Disclaimer: This is a simplified estimation. Actual FPS may vary significantly based on the specific game, its optimization, driver versions, background applications, and other system nuances.";
