Chrome Experiment "Liquid particles" runs extremely slow compared to chrome without hardware acceleration enabled. Chromium provides fluid animation on particles, while Minefield runs approximately 10 fps. Scenario "Liquid letters" runs equally slow on both, regardless of hardware acceleration 

Reproducible: Always

Steps to Reproduce:
1. Load the web page
2. Click around to manipulate the particles
Actual Results:  
Very slow redraw rate compared to chromium nightly.

Expected Results:  
Ideally, Chromium and Minefield should be equal speeds.

No noticeable difference when hardware acceleration is off

So, I don't understand. The two above sentences seem to be contradictory. Is it with or without HW acceleration, that you noticed a large speed difference between chromium and minefield?

Also, it's always useful to include the name of your graphics card and driver version.

Sorry. There is no noticeable difference in "Liquid Letters" regardless of hardware acceleration or browser. Liquid particles is slower than chrome without hardware acceleration, but there is no noticeable difference between minefield and chromium with hardware acceleration on

Here's my graphics info:
