99% utilization of the GPU can of course result in increased temperatures, and I can see why that would be less than ideal in a laptop.
But since you don't mention anything about it, I suppose you are not dealing with overheating issues or any other negative impacts from the increased GPU utilization?
I don't see why very high GPU utilization is a bad thing, it should help increase game performance and give you a better gaming experience.
So if it isn't resulting in negative consequences like overheating and / or potential thermal throttling issues, the high utilization should be a good thing.
If the performance was suffering from very high temperatures and temperature related throttling problems, naturally it would be different...
