RAM usage:
The game off, 1.6GB used
turn on the game, 3GB used
start a 1v1 game, 5-6GB used

I already changed all my graphics settings to Low when i do the test
From my memory, before the October Patch came out, when i'm playing 2v2s for 6 hours, memory usage is only around 3-3.5GB (the game flushes it after every game); now it seems like it doesn't do its job correctly = memory leak
Anyone experiencing similar symptoms?
If it is, then Relic's patch screw up something else again
