I would like discuss here some gaming tweaks, which don't give sense to me.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games]

For example "Priority"=dword:00000001
On msdn they mention, that priority 1, means low priority.
I know, that high priority is not recomended, because it might affect stability of system, but low make no sense as well.
In process lasso appears below normal, like low.

"SFIO Priority"="High" i have that in registry and process lasso showing me still normal, weird.

"Scheduling Category"="High" this i understand, you want more priority to sheduling your game at first place, what makes stranger, that priority is recomended to low.
I don't understand much what priority alone does, especially if you want keep it on low.

And what do these 2, affinity you set at launch parameters with mask today times, or ingame, so that probably doesn't matter.
"Clock Rate"=dword:00002710 (default: 2710, recommended: 2710)
"GPU Priority"=dword:00000001 (default: 2, recommended: 1)
Again i don't understand why 1, it is lowest priority from 1-31.
