I recently got a new comp with windows 10, 32g RAM and i7 processor. Internet is fiber. Tried every browser I could think of to resolve meter issues. Initially the most stable ended up being Comodo Dragon. Maxathon in retro or other settings was manageable but not great.
Then I tried Vivaldi from the creators of Opera. Ridiculous meter like butter and consistently stable. Better than anything I had prior to windows 10. Hope this helps someone, only one I found and I've tried just about everything:
