WOW poor performance on Y50-70

Hi!

I own a Lenovo y50-70. It's not any good machine, but it still has a decent organs, like gtx860m, 8bg ram and i7.

Even though, the organs are okay, the recommended settings in WOW are on 6/10. Even on those settings I lag on raids, in populated areas. Not to mention brawls, on which I cannot even move.

Are there any tips on running WOW smoother?

Thanks in advance!
The gpu is the biggest bottleneck. It's only a bit better than a low end GT 1030.
Yes, but World of Warcraft is 14 years old...
The current iteration of WoW is less than a year old. Actually, Zinthax, and yes, it requires a modern PC to run well. Just like any other game less than a year old.
