I wasn't able to get this posted yesterday, but I hope that maybe it'll still help. Judging from the comments on the download page, Lots of people seem to have a problem or two with the concept of different hardware capabilities, & here I mean chiefly what I most often refer to as horsepower -- horsepower isn't really accurate at all, but it's a term most people can understand & relate to.
Generally, cheaper hardware has less horsepower, if for no other reason than manufacturers can charge more for more powerful systems & components. Nowhere is that as apparent as with graphics cards, where they often start with a higher end model, then create cheaper models by disconnecting &/or removing stuff [in many cases their cost is the same]. And if you've got less capable hardware [with less horsepower], it's going to be slower than top of the line versions, period. Nothing will ever change that. CPU manufacturers' cheaper products are most often CPUs that fail their tests for the top models -- when they don't have a high enough failure rate, they go to extremes to make sure you cannot unlock that added power [occasionally they've failed, creating legendary products BTW].
No software can possibly be a cure for a lower horsepower laptop or PC, & that includes Process Lasso. That laptop or PC is what it is, & the only thing you can do is use it that way, or ask it to do less, e.g. run a more stripped down version of Windows or Linux. I got a stripped down version of XP Home running on a old win98 laptop just as well as [if not better than] minimal *nix installations. With Microsoft trying to port win8.1 on everything imaginable, there's hope there too as they keep reducing its requirements.
Where Process Lasso might make the biggest difference is on mid range hardware -- those systems have got enough horsepower that users tend to load them up a bit more with background apps, services, & processes that the lowest end stuff can't reasonably run. There Process Lasso can often juggle resources better, so those apps & services don't cost as much in terms of performance.
If you've got a more powerful, i5 or i7 gaming rig [which are often overclocked as well], you probably don't have a lot of background stuff running, because the stuff other people have running that way just doesn't interest many serious gamers. At the same time those rigs are often powerful enough that the stuff win7/8/8.1 has running in the background is hardly noticed, so even if Process Lasso eliminated their load on the system entirely, there would be no real perceivable gain.
So, long story short, does Process Lasso work as advertised? It certainly does. It just doesn't make sense for everyone.
