Just commenting to all the "This is placebo" and get the better "free Lasso" blablabla



What does the program do?

It's main purpose seems to basically chooses the cpu cores/threads for the games/programs to use. You can do it manually without any program in the task manager (or in case using cpucores, you can also see what cpucores chooses to use). Windows default is allow appllication to use all cores/threads.

Task Manager(ctrl+shift+esc) -> Details tab -> right click on application -> Set affinity ->select cores you would like to use and click ok



Now why does this matter for me?

In my personal case, I don't use it to "gain perfomance" but to fix problems in many cases. Many older games have problem with running on too many cores. GTA SA has mouse "bug" where it just sometimes won't change character direction after exiting the menu, if I don't limit the amount of cores used. Prototype doesn't even load to game (just closes it in the middle of loading) if i use all the cores.



So why not do it manually in Task manager?

Because my experience is that Task Manager does not retain the affinity values of the programs. CPUcores can be set to autostart



So where does all the alleged "extra performance" come from?

Since operating system mainly uses the first core of the the cpu for it's own processes, loading the the game process on same core also, may impact the game performance negatively. Not using the operating systems main core for game or application process(es) adds the possibility of "extra performance" since it does not have to compete with operating system on the same core.
Second thing is Hyperthreading or SMT; using every single physical core as 2 virtual cores (threads). This will basically make possibility to consume single physical core with the worth of 2 core workload and in some game cases having those workloads on separate physical cores will have the possibility of "extra performance" since it won't have to compete with itself on those physical cores.



So why not Process Lasso?

To be honest, could not care less if you use Lasso, cpucores, do it manually or use some other program; everyone chooses what he/she uses. The comments about lasso "is free" is not correct. It's trial is free, it's paid lifetime version is more expensive than cpucores deluxe. Is it better or worse can't say; I don't require the additional functionality Lasso offers and I like the easy solution that cpucores is: It is downloaded and started from where my games also are and it is not with too many options, that i will never use anyway.

That is my experience using it, hope it helps someone
