It depends. On my Main Computer on which i play LOL i can run 8 VM's at the same time
Specs:
CPU: I5
[email protected]
RAM: 16GB
GPU: Nvidia 660GTX
HDD: 3TB 7200RPM
I Tried more then 8 Bots but the CPU is at 100% with 8 Bots already and the Ram is at like 10GB
However if im sticking to 5 Bots at the same time i can even play LOL outside of the VM with still 100fps.
I still guess the Bottleneck is my HDD which sounds like an Ferrari on Crack when they are running. So im Planning on buying a SSD
Update is out and Bot is already in Queue
