Using firefox, the game stuck when matching with some guy, spiked to 12% cpu usage (one full thread/core) and 2.2gb ram usage (the most a 32bit app can allocate.) if i didn't have the computer i have, this would have been unpleasant, Yeah did some more tests, here's what i found: When the peoples' names is displayed after selecting the order or chaos, and you click the screen, memory usage spikes by 90-120mb per click. I'm guessing there's some intensive stuff going on, but if you're impatient, you can quickly go from using 300mb to using 2gb.
