-_* With Firefox 27 about:config adjustments webgl.prefer-native-gl = true, and
-layout.frame_rate = 500, asm.js can do 4913 @ 60Hz._
+To test browsers in 60Hz mode following changes were made:
 
-asm.js build is here: [https://gist.github.com/bkaradzic/9594247](https://gist.github.com/bkaradzic/9594247)
+ * Firefox 27 about:config adjustments: `webgl.prefer-native-gl true` (on Windows),
+   and `layout.frame_rate 500`.
+ * Chrome 33 command line option: `--disable-gpu-vsync`.
+
+#### 30Hz (test for browsers)
+
+By default browsers are using vsync, and don't have option to turn it off
+programatically.
