How MyRigCheck works

1. Rig Power Score

Your Rig Power Score is the average of two calibrated hardware scores — one for your CPU, one for your GPU — normalized to a 0–100 scale where a top-tier modern build lands at 100. The score is then bucketed into one of five tiers: Elite (88+), High (70+), Mid (48+), Low (28+), or Minimal (below 28). It's a quick way to compare rigs against the 350,000+ titles in our catalog without running each one.

2. FPS Estimates

FPS estimates are computed from your hardware scores, the game's documented minimum and recommended requirements, the resolution you're checking, and a performance-scaling profile that adjusts for resolution cost. Results are calibrated against observed benchmarks for popular titles; for less-tested games the estimate is approximate. We surface a confidence percentage so you can tell the difference between a 90%-confidence estimate and a 60%-confidence one.

3. Bottleneck Detection

We estimate the relative load your CPU and GPU are under at each resolution. The component that hits 100% utilization first is flagged as the bottleneck. If both are near their limit, we report the system as balanced. Laptop thermal adjustments are applied automatically when you mark your rig as portable.

4. Hardware Auto-Detection

When you grant permission, we read your browser's WebGL renderer string and User-Agent to identify your GPU. CPU detection uses the User-Agent CPU hint where available. The detected hardware is then matched against our reference database of canonical SKUs. Hardware we can't match falls back to manual entry.

5. Data Sources & Update Cadence

Game metadata, genres, themes, and platforms come from IGDB. Steam review counts, peak concurrent users, and pricing come from the Steam Store API. We re-ingest and re-index our read layer weekly; the data-refreshed timestamp in the footer tells you when the last build completed.

6. Limitations

Estimates don't account for every game build, every driver revision, or every background process. The model under-estimates on games with heavy CPU single-thread dependence and over-estimates on poorly-optimized ports. We do not currently support console platforms. If you spot a result that's badly wrong, the community FPS report button on each game page lets you submit observed numbers — your reports feed the next calibration run.

Frequently asked questions

How accurate are the FPS estimates?

FPS estimates are computed from calibrated hardware scores and the game's documented requirements. They're calibrated to within ~15% of observed performance for most modern titles, but they are estimates — actual frame rates vary by in-game settings, driver version, background processes, and the specific game build.

What is the Rig Power Score?

Rig Power Score is a single number from 0 to 100 derived from your CPU and GPU hardware scores. It buckets your rig into one of five tiers — Elite, High, Mid, Low, or Minimal — so you can quickly compare against the database of 350,000+ games.

How does bottleneck detection work?

We compare the relative load your CPU and GPU are under at each resolution. The component that hits 100% utilization first is flagged as the bottleneck. Balanced systems are reported as such, with no dominant bottleneck.

What data sources do you use?

Game metadata and system requirements come from the IGDB (Internet Game Database). Steam review data, peak concurrent users, and pricing come from the Steam Store and SteamSpy-style estimates. Rankings and community benchmarks are recomputed weekly.

Why did auto-detection fail to find my hardware?

Hardware auto-detection uses WebGL strings and browser User-Agent hints. If you're on a browser that blocks WebGL, a hardened privacy browser, or have an unusually new GPU that isn't in our reference database, detection will fall back to manual entry.

Is my rig data shared with anyone?

No. Your rig profile lives in your browser's local storage and a small anonymous cookie used for server-side compatibility scoring. We never sell or share individual rig data, and you can clear it any time from the My Rig page.
