I noticed on version 1.19 its taking some 3% to 5% of cpu usage, so going back to 1.18.
I dont mind the ram usage at all, both use 15mb wich is nothing and perfectly fine:
1.18 task manager shows its process 0%
1.19 task manager shows its process 3% (this will increase cpu heat a bit and afect performance while testing it for gaming)
Next version hope your able to make it run like in 1.18 (process 0%)
Forgot to mention im using: Windows 7 Home Premium 64 bit
