Just hit start (or the enter bar, in this case) and get to collecting stars. Yep, the classic game is available right now at this website for free, unlimited play, no downloads or emulation back-end required. Once the intro is finished and the start screen is shown, though, the frequent compartmental GCs start again (I suppose it would stutter, too, but there's not enough movement to see that): During the intro, there are only two short global and one compartmental GC, which cause a slight stutter (but that's less noticeable than in the Mario Bros. The Lemmings ROM runs with a slightly higher overall FPS than the Mario Bros. It seems like, while the GCs are very fast, they are enough to cause a very noticeable stutter because the CPU is already maxed out even without them. While a ROM is running, I get very short compartmental GCs almost exactly every 500ms: In a clean profile with today's nightly, I get 54-58FPS, but movements stutter every few hundred ms or so. Unfortunately, on my mid 2009 MBP (2.8 GHz) with OS X 10.7 the ROMs still don't play without stuttering.

This is an unfortunate side effect of developers typically having machines much faster than the average user.Ĭan someone else without a superfast machine do the same test as above? Reopening for now. So on my machine, Fx is about 100% slower (2x) than Chromium in this testcase.

When the game gets to the start screen note the current time.

Click Restart and note the current time.Ĥ. Select Lemmings and wait for it to download.Ģ. Some of the simpler games hit ~58 FPS but Lemmings shows a significant difference.ġ. If you get 58-60 FPS in Fx then your computer is probably fast enough to hide any performance difference because the source has:įx version: Mozilla/5.0 (X11 Linux x86_64 rv:12.0a1) Gecko/20120118 Firefox/12.0a1Ĭhromium version: 15.0.874.106 (Developer Build 107270 Linux) Ubuntu 11.10
