All Technic Launcher Modpacks Lag

[CommanderPrimeYT]

Hi,

I am having a problem which is really annoying me. After upgrading to windows 10 my Minecraft (Vanilla) has been acting really slow and nothing I can do can make it work like it should do. The only thing that helps a little is by using the default setting (1GB RAM, I was using 4GB RAM) and on technic I have the same problem but when I run vanilla minecraft on technic with 4GB RAM it works perfectly fine with no problems at all. I am slightly stumped by this and was wondering if anyone could help me.
