DESCENT: measured
We loaded DESCENT in a real headless Chrome, played it, and recorded what it did. Blank cells are facts we could not measure, not zeros.
| Download | 632 KB | Total bytes fetched on first load. |
|---|---|---|
| Loads in | 25.8s | Time to the load event on a desktop connection. |
| Frame cost | 161 ms (~6 fps) — 9.6× over the 60 fps budget | Cost of one frame while playing, sampled in a headless browser with vsync off — so this is how long the game takes to draw, not the rate your screen refreshes. A 60 Hz display allows 16.7 ms; 95th percentile 430 ms. |
| Renderer | ANGLE (AMD, AMD Radeon(TM) 610M (0x0000164E) Direct3D11 vs_5_0 ps_5_0, D3D11) | What the game draws with. |
| Requests | 3 | Files fetched — a low count means a self-contained build. |
| On a phone | Fits a 390px screen | Measured in a 390×844 viewport. |
| Source code | Open source on GitHub | github.com/sjwebster-bne/downhillmtb — you can read or fork it. |
