Launches Gw2-64.exe with thread affinity
Guild Wars 2, like most games, appears to run better when only using one logical core per physical core. This program (once compiled) will execute the included batch file, and launch GW2-64.exe so that it only uses cores 0, 2, 4, and 6. Since I designed this program for quad-core hyperthreaded processors, you will need to modify Gw2-64-affinity.bat if you want to specify different cores. I've split the program into two files so that users can specify which cores to use or which exe to launch without having to recompile the program.
start /affinity 55 Gw2-64.exe -mapLoadInfo -autologin
exit
"/affinity 55" selects which cores to use. How? Each core is tied to one bit in what I'm presuming is a one-byte value. You must convert these values (1, 2, 4, 8, 16, etc.) to hex, and then add them up.
Core 0 = 1
Core 1 = 2
Core 2 = 4
Core 3 = 8
Core 4 = 10
Core 5 = 20
Core 6 = 40
Core 7 = 80
It may be possible to go higher for 6 or 8-core processors, but I haven't tested it. Here are the numbers you'll need for different CPUs:
Single-core: 1
Dual-core: 5
Quad-core: 55
"-mapLoadInfo" and "-autologin" are launch parameters that I like to use, feel free to remove them or add your own. If you don't use the 64-bit beta (which you should), simply erase the "-64" from "Gw2-64.exe".
