After years of having dealt with laggy issues due to Computer performance. I have finally come across something that helps a tremendous amount. Its called GameBooster.
GameBooster has a simple button called "BOOST" as soon as its opened up. This is a description from there site;
"Game Booster 3 is capable of delivering the best gaming experience to you even if you have an old PC. One-click to boost PC performance is not enough, Game Booster 3 also allows you to tweak your system for top PC performance. By temporarily shutting background processes and unnecessary Windows services, cleaning RAM, and intensifying processor performance, Game Booster 3 concentrates every little system resource for gaming only."
I recommend this as I am sure you have heard me complain about my computer's ability to run minecraft.
Specially those of you from the mineology Era.
Anyways this helped me out and I hope it's of good use to those whom have the same problem as I.
