I'm a big fan of XQN, but I seem to be having some problems with the wallet...
When I'm playing a game online, I get serious lag and rubberbanding, making most of the games I play completely unplayable (Call of Duty series, Battlefield 4, Titanfall, Path of Exile, etc.) unless I close my wallet. I can still have half a dozen other wallets running with no impact (I spent the last two weeks trying to figure out why my games wouldn't play anymore).
Has anyone else had this problem? Does anyone have any ideas of how I may be able to fix it?

Thanks!

This is probably because the Quant tab auto-updates every 2 minutes in the background, and it is doing drawing operations to update the graphs. Next update there is a checkbox to turn off the auto-update just like on the profit explorer tab, and that will probably solve it for you (just uncheck it before playing your games).
