I did change the GPU settings and nothing changed. I did recently upgrade the GPU to see if that would fix the problem with no luck. It is from the same company though . I have been itching to upgrade to an I7 CPU with a new motherboard and even more memory, this might just push me to do it. That might not fix my problem but it might keep the CPU form hitting 100% when working in lightroom . I am running windows 10 and not sure if i will go back to win 7 or not when i eventualy upgrade.
