ProcessAffinityMask

So on a hexacore machine it's: 1+2+4+8+16+32=63 ?

Thanks

Here's how you calculate those affinity mask numbers:
128 64 32 16 8 4 2 1

So if you wanted the game to use only the first two cores you would set it to 1+2=3. If you wanted it to use all 4 cores on a quad core machine it would be 1+2+4+8=15.

From my experience with other games, hyperthreading on a quad-core is counter-productive so turn it off. In addition freeing up the first core for windows seems to reduce micro-stutters (in other games I'm talking about here like FSX)

I've found 14 to be the sweet spot for my system (using cores 2,3,4 core 1 free for windows)

Yes, you got it! (111111 binary to decimal conversion = 63)

Good to see you around again Flushy!

Well,

at least for me it doesn't work.
I changed it to 14 but still my first core does most of the work.

the ; in front of it is removed i assume. Does it save it or does steam put the files back to original?

Only for the rest of my life! It just keeps getting better and better. The pits seem to be really squared away this time round too, (Slotted screw heads and all!)

Yeah, what he said. So on a hexacore machine it's: 1+2+4+8+16+32=63 ?
Anyone have an answer for this? With an i7 980X extreme is there really any point in turning off Hyperthreading? I mean I would love to optimize but it is running prettty good right now. Guess more is always better? Nah, sometimes that isn't true.

Since the patch I am sure the multicore support is working, and I think it works regardless of the settig you have.. I left mine with the semi colon in front and all 4 cores worked fine...
