Okay. I have another ISBoxer update that should help.
- Code:
ISBoxer 39.1.810.1
* Improved the default CPU Strategy for dual core (or fewer) processors, by not using a Master Slot. Also fixed a bug with not using a Master Slot, where it would still reserve a dedicated CPU
Download it through the About window (Help->About)
After the update, the CPU Strategy wizard should a) automatically select <NO SLOT> during the wizard, and b) generate a different strategy than you're currently using.
I think this is the only difference between 39 and 38 as far as any of this is concerned. ISBoxer 39's default CPU strategy -- from 39.1.807.1 and earlier -- assigned your cores like this:
Slot 1: 1,2
Slot 2: 3,4
Slot 3: 3,4
Slot 4: 3,4
Slot 5: 3,4
39.1.810.1 will instead use this by default:
Slot 1: 1,2
Slot 2: 3,4
Slot 3: 1,2
Slot 4: 3,4
Slot 5: 1,2
You can configure these yourself at any time per Slot in your Character Set. To do so, select your Character Set in the top pane, then in the bottom left pane select each Slot number. Highlight numbers in the CPU list to assign those CPU cores.
Your dual-core i3 is Hyper-threaded, so your 2 cores will show up as a real core and a fake "logical" core. As I understand it, they are designed to be used in real+logical pairs, and if you assign a game instance only to logical cores, it will be slow. So that's why they each get two cores, and why 1 goes with 2 and 3 with 4.
Also, I usually recommend getting as close to 1 core per game instance as possible. A quad core processor would handle 5 characters a lot better than a dual core.
Hope this helps
