Which core is 90*C? Is it Core 1?
( It goes Core 0, 1, 2, 3 )
I don't like 90*C. But if that's only one core, apparently it's a thermal probe not being so accurate on that specific core. I always have a core that's like 5*C hotter than the rest.
Doesn't matter if you're plugged or not, your card will automatically be throttled as far as I'm aware and will use the Intel GPU.
I have a G750JX, WITHOUT Optimus, so I am not sure.
