Generally my HEM2 is doing fine but it becomes very laggy if I open HEM2 notes during the gameplay to write down some info.
Entire system becomes barely responsive and it takes quite some time to write down notes and close it, making me not able to react to other tables.
System: Windows 8.1
HEM Version: newest
Hardware: i5-4670k, 8GB, SSD, low temps
I am not using NoteCaddy.
