In the nvidia control panel set the "threaded optimization" option to on (options are auto, on and off)

I suppose it will work with quads but may be you need to add more processaffinitymask=0-15

Next table gives an explication on which cores will be used so that A= active core and X= non active core

ProcessAffinityMask CPU-Usage
0 A A X X ....................(cores 0+1 used)
1 A X X X ....................(core 0 used)
2 X A X X....................(core 1 used)
3 A A X X....................(cores 0+1 used)
4 X X A X
5 A X A X....................(cores 2+4 used)
6 X A A X
7 A A A X
8 X X X A
9 A X X A
10 X A X A
11 A A X A
12 X X A A
13 A X A A
14 X A A A....................(cores 1+2+3 used)
15 A A A A .................(cores 0+1+2+3 used)

For core quads I would test:

processaffinitymask=1
processaffinitymask=2
processaffinitymask=4
processaffinitymask=8
processaffinitymask=15



Let me know
