Am I the only one who gets poor performance?
When I drag around the first map quickly, I get about 5 FPS, and the "chrome" process on my system jumps to 100% CPU usage (running Chrome 35.0.1916.153). The same with Firefox Nightly (33.0a1), although the FPS is higher here (10-15 FPS). My CPU is an eight-core AMD FX-8320.
