  2. Lvl 02

    Score

    GPU matched to a benchmark score

  3. Lvl 03

    Compare

    Score vs the game’s requirements

  4. Lvl 04 Goal

    Grade

    A verdict from S to F

Step 1

Instant Hardware Detection

Your browser already knows your hardware. We just ask it the right questions.

WebGL

GPU Detection

We create a hidden WebGL canvas and query the WEBGL_debug_renderer_info extension. This returns your exact GPU model — no downloads, no plugins.

console
UNMASKED_RENDERER_WEBGL
"ANGLE (NVIDIA, GeForce RTX 3060 Direct3D11...)"

Works in Chrome, Edge, Firefox, and most Chromium browsers.

Navigator API

CPU & RAM

navigator.hardwareConcurrency returns your CPU’s logical core count. navigator.deviceMemory reports available RAM (capped at 8GB in Chromium).

console
hardwareConcurrency → 12
deviceMemory → 8

Firefox and Safari don’t support deviceMemory. Use the manual dropdown to set RAM.

Manual Override

Select Your Exact Hardware

Browser detection has limits. That’s why every spec has a dropdown — select your exact GPU, CPU, and RAM from our database of 182 GPUs and 97 CPUs for precise results.

How We Grade Games

A simple ratio-based comparison weighted by component importance.

Try it: move your GPU

Example game: Game’s rec. GPU 15,000 · RAM 16 GB

B Solid
Your GPU 17,050
Game’s rec. GPU 15,000
Ratio 1.14x
Your RAM (game asks 16 GB)

GPU only 1.14xFinal 1.14x

The S/A/B/C/D/F Tier System

Every game on the site gets one of these six stamps for your exact hardware.

  1. S

    Overkill ≥ 2.0x

    Your PC destroys this game. Max everything.

  2. A

    Smooth ≥ 1.3x

    Runs great at high/ultra settings.

  3. B

    Solid ≥ 1.0x

    Meets recommended specs. Solid experience.

  4. C

    Tight ≥ 0.75x

    Between minimum and recommended. Medium settings.

  5. D

    Struggles ≥ 0.5x

    Below minimum specs. May struggle at low settings.

  6. F

    Won't run < 0.5x

    Hardware too weak. Don’t buy this game for this PC.

Understanding

Minimum vs Recommended Requirements

Game developers publish two sets of requirements. Here’s what they actually mean.

MIN30 FPS · low

Minimum Requirements

The absolute lowest hardware to launch and play the game. Expect low settings, 30 FPS or less, and possible stuttering. The game "runs" but the experience may not be great.

Typical example: GTX 1060 · 8 GB RAM · i5-6600

REC60 FPS · medium-high

Recommended Requirements

The hardware the developer targets for a good experience — usually 60 FPS at medium-high settings, 1080p. This is what CanIRun.gg primarily compares against for grading.

Typical example: RTX 2060 · 16 GB RAM · i7-8700

Our own data

Share of Steam players who can run each game

Every game page shows what share of Steam players own a graphics card that meets the game's minimum and recommended GPU. It comes from crossing the Steam Hardware Survey with our GPU scores.

01

The survey

We take the all video cards table from the Steam Hardware Survey for September 2026. It is the Windows PC table, the one that matches the requirements we grade.

02

The matching

Each card is matched to our GPU score table with the same rules the site uses to read requirements. Reasonable variants are grouped (the RX 580 2048SP counts as an RX 580) and a laptop GPU only matches its laptop version.

03

The math

For each game we add up the share of users whose GPU scores at or above the minimum and, separately, the recommended. We divide by the matched part, so the result is a share of the GPUs we identified.

September 2026 Survey The month the site uses today.
82.6% Coverage Part of the survey we matched.
78 GPUs Models from our table that show up in the survey.
17.4% Unmatched Left out of the math.

Limits

  • It only measures the GPU: not the CPU, RAM or disk. A PC can have the card and still fall short elsewhere.

  • The Steam survey is a voluntary monthly sample. Valve does not publish its size and the shares can jump from one month to the next.

  • 17.4% of the survey stays unmatched: Steam's own "Other" bucket, generic integrated graphics and models not yet in our table (NVIDIA GeForce RTX 4050 Laptop GPU, AMD Radeon Graphics, Intel(R) UHD Graphics). Many are modest GPUs, so the real share can be somewhat lower.

  • When Steam doesn't name a GPU in the requirements, the game's score is estimated from VRAM or the DirectX version, and the share inherits that estimate.

  • We update it every month, when Steam publishes the new survey.

FAQ

Frequently Asked Questions

01

Is this really free?

Yes, it is free to use. No subscriptions or premium tiers. CanIRun.gg is built by a solo developer and supported by affiliate links (for example, Amazon) at no extra cost to you.

02

Do I need to download anything?

No. CanIRun.gg runs entirely in your browser. It uses WebGL and Navigator APIs to detect your hardware. No software installs, no browser extensions.

03

How accurate is the hardware detection?

Very accurate for GPUs — WebGL reads the exact GPU model from your browser’s rendering engine. CPU detection is limited to logical core count, and RAM may be capped at 8GB in some browsers. You can always override any value manually using our dropdowns.

04

What games do you support?

CanIRun.gg currently tracks 13,000+ Steam games, including the most popular, trending, and anticipated titles. The database grows daily via our automated data pipeline.

05

How do you check if my PC can run a game?

We detect your GPU, CPU cores, and RAM via browser APIs. Your GPU is matched to a performance score in our database. That score is compared against each game’s minimum and recommended hardware requirements to produce a grade from S (overkill) to F (can’t run).

06

Can I check for laptops and handhelds?

Yes! We have 67 gaming laptops and 30 gaming handhelds in our database. Select your device model and instantly see compatibility with thousands of games.
