Mouse freeze

Hello there,

During my games since 2 weeks ago,every 2 or 3 min i'm experiencing a mouse freeze for 20 secondes. it's not exactly a freeze but the path of my cursor isn't smooth anymore it stops for 1 sec then goes instantly to another direction and doesn't move for 0.5 sec etc...

I thought my mouse had a problem , but i changed it and my touchepad reacts the same way. I encounter this problem only in LOL. I also updated my drivers, do you have any solution?

Thank you in advance,

Best regards,
