Hi there,
perhaps someone could use a working app_info for running MW optimized? Here are two versions, the former reserving an entire CPU core/thread for four WUs, the latter reserving as much as stock:
First go here and download the application and an included app_info you will have to replace by the contents following later (click)!
Second here is the first app_info content reserving an entire thread/core for MW:
Code:
milkyway
Milkyway@Home
milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe
milkyway
102
2.5e11
0.250000
0.250000
opencl_amd_ati
ATI
0.250000
--process-priority 4
milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe
Then there is the version that will reserve only as many cores/threads as the stock application:
Code:
milkyway
Milkyway@Home
milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe
milkyway
102
2.5e11
0.050000
1.000000
opencl_amd_ati
ATI
0.250000
--process-priority 4
milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe
Hope this helps some people here! 
And btw, be warned that MW atm does not really like OC on GPU cores, at least for my two setups with OCed CPUs and stock OC editions of 7970s! I had a huge bunch, in fact entire sets of 80 tasks each fail this morning due to OC... 
And desynchronizing the tasks may help at other times, but right now there are three different types of WUs (*free*, *sample* and *edge*, each for basic types *ps* and *de* IIRC) taking entirely different average times, so they will synchronize and desynchronize all by themselves again and again, if they do not fail first...
