Appears to be some sort of a leak with CPU usage, over time it spikes randomly.
Just fired it up and uses mere 1,5% off my i5 3570k.
Before rebooting it, DeepBot was running for ~24h and usage was on idle (not streaming) around 10%.
On active usage (streaming, giving points, having bets, heists etc) it spikes between 10% and 20%, after several days it's consistent usage seems to be around 25%+.
