Laptop at 99% performance, nowhere near 100% performance, why is this?
edit: When I talk about CPU performance % it is not the load but the max usage setting.
I have a laptop with windows vista, AMD turion dual core, 3GB ram, and Nvidea geforce 8200 GPU. I use power plans to limit my laptop CPU to 95% performance. This keeps the temperature down and I never notice much difference in most games or outside of games.
With the minecraft beta update that came today, the game was unplayable. 1-2 FPS, previously it worked great. So I tried setting my performance to 100%, it ran great, 30+ FPS it was just amazing. Set it to 99% and it ran horrible again.
My question is, how does vista's built in processor speed limiting system work. Is it really 99%, or a much less accurate rating, because I cannot believe 99 and 100% could make this much of a difference. I have experienced this with a few other games as well, but usually it seems to make no noticeable difference.
edit: also could I somehow be lowering my GPU performance unwittingly? I took the balanced power plan and just lowered the CPU slider to 95 and 99% everything else was the same.
