yep pretty sure that is what's causing it, been browsing on mx450 for an hour now, not a single time has it lagged, meanwhile on integrated gpu it would have done it a lot by now
also i wanted to mention, the suggested way of installing igpu drives and the screenxpert software just doesn't work for some reason, after some time it starts lagging,
how should i go about stopping that, a complete reset works fine until some update destroys it.
