What are those numbers?In gaming I don't see any sudden performance drops/loss. So to me, that's "acceptable" and what I'd expect from a gaming laptop that was before the the NVIDIA Max-Q design, running a (terrible) Kaby Lake chip, and in a 13.3" chassis. I guess we just have different expectations...
You've tried calling any of these?
Also, my games crash frequently on the laptop, and I think a sudden 95c+ peak and throttling flickering on an off - all before the fans can react - might be the cause.
