It doesn't make sense to choose the GTX card on battery - not this generation anyway - what I was asking was does the Intel GPU, sometimes, run instead of the GTX discrete card on AC power - while plugged in? And, is there a way to force GTX Graphics only when plugged in? Maybe a Power Plan option? Discovered this by accident one day.īIOHAZARD9519, I didn't exactly mean the CPU will run "hotter" as in MAX temps, as the CPU cooling will prevent high temps, what I meant was the CPU die will generate more heat due to the on CPU GPU running alongside the CPU - both generating heat, whereas on the G750JW/JX/JH the Intel on board GPU is inert - and the Graphics tasks heat is generated and cooled on the other cooler.Īnd, as far as the Optimus disabling, I meant on AC, not on battery. Basically 6:45 down to 3:00 battery life. A work-around would be to keep Nvidia Shadowplay running, which forces the GPU to stay on even at desktop, but it consumes a lot more battery. When running on it, the fan still blows relatively warm air, sometimes cool.Ībout optimus disabling, I went and checked and couldn't find any way to. I doubt the CPU would get that much hotter. I wonder if side by side the new G750's are noisier - run the fan more often, doing the same tasks - that only use the CPU compute/graphics and don't use the GTX card / cooling?Ĭan the new laptops disable the switching between the CPU / discrete GPU on AC power, forcing all graphics to use the GTX discrete card / cooling? That means the CPU will run hotter, since it is doing the work of both the compute and graphics, no wonder Asus increased the cooling capacity of the new G750's by changing from the lighter heat sinks to solid copper heat sinks.Īnd, that means the CPU fan will run more often on the new G750's.
