Well, I don't trust IObit at all. Not after what it did to my computer. I had the Advanced System Care program and it screwed my laptop over. had to reinstall Windows and all my stuff. Thumbs down for me. However, there IS another program that can shine upon Frame Rate laggers.
Tune Up Utilities beats GameBooster like a 1000 times more.
You can disable programs running in the background (it tells you what it is).
You can create a Turbo mode like GameBooster but more in depth.
You can set your windows appearance to reduce graphic load.
It's a five star program and 96% customer satisfaction rate with over 4300 reviews.
This program costs about 60 bucks but you can easily get pass with a cracked version (hint: just search on youtube).
QUADRUPLE THUMBS UP FROM ME!!! (I'll just have to find some kind of radioactive mutation chemical to grow myself another 2 arms lol)
However, there is a 15 day trial (full features). Feel free to just get the trial even though you won't buy it because free is free and you can just somehow get the trial and use it again. ALSO, it modifies your internet connection if you wish it to for a faster download + upload rate. FURTHERMORE, you can disable programs at start-up for a quick start.
