Weird Performance Problem

Hi Guys,

I'm experiencing a strange problem. I have three regions and I swap between each region on separate dual monitors for two characters (1 main, and 2 overlapping home regions on the secondary monitor for swapping so the secondary window is always in the same place). I'm finding whatever is my "Slot 1" character has excellent FPS performance when in my main region however "Slot 2" character seems to take a very large performance hit in the main region while "Slot 1" character in its home region still seems to have the same performance as it did when it in the main region.

In-case this is confusing: (Because when i re-read it i even confused myself a bit)

Region 1 = NO SLOT (Active and Reset Region within swap group)
Region 2 = Slot 1
Region 3 = Slot 2

Slot 1 in Region 1 & 2 has excellent performance
Slot 2 in Region 1 & 3 has consistent reduced performance

Is this normal? I would have thought that whatever is in your main region would be given full performance whereas a character that is not in the main region is set to have decreased performance.

Can anyone advise how i can resolve this issue? I am running Windows 7 SP1 x64

EDIT: I should also note that Slot 1 is using CPU core 0 / 1 / 2 and Slot 2 is using CPU core 5 / 6 / 7 on an i7-2600k

Windows lists your cores 0 - 7, and ISBoxer lists your cores 1 - 8. Since you mentioned core 0 I'll assume you're using the Windows label to describe what's going on. If that is the case, then core 5 is a virtual core and shouldn't be assigned to Slot 2 w/o having assigned core 4 to it as well.

As Windows shows it:
Real cores - 0, 2, 4, 6
Virtual cores - 1, 3, 5, 7
Cores paired up with each other - 0/1, 2/3, 4/5, 6/7

If you assign a virtual core without it's counterpart, you're going to see some weird performance. You'll want to keep them paired up with each other and the CPU Wizard should have taken care of this for you.
