How does Process Lasso work?

Anyone use Process Lasso?

Wondering if it's all it's cracked up to be. Apparently, it does some OS "tweaking", dancing around program/thread/processor priorities.

My knee-jerk reaction is that any type of program that messes around with Windows' core CPU/thread management is asking for trouble. But I don't know much on the matter.

Is Process Lasso useful? Will you see much benefit, if any? In particular, besides overall system use (like browsing with 150+ tabs open, pushing 10GB of memory), I'm interested in whether using Process Lasso would help one's framerate when playing GPU-intensive games, like Far Cry or Starcraft.

Who the hell has over 150 tabs open?? I usually have 20 or 30 at most.

Personally I'd be wary of that software.

The same as you said.
Windows has a particularly bad problem dealing with threads that decide they want to consume every bit of CPU time they can get their hands on (a CPU bound thread). A single 'CPU bound' thread running at Normal priority can bring an entire single-CPU system to a stall, as demonstrated by our graphical proof of concept below. Yes, it is true - believe it or not! It is this worst case scenario that Process Lasso was originally written to address. By temporarily lowering the priority of the offending process, your PC can be saved from a virtual stall. It was later discovered that, with a few refinements, our algorithm could improve system responsiveness during periods of high CPU loads - in addition to saving the PC from a worst case scenario.
