Ive noticed when im playing in normal areas where there next to no one my gpu runs at around 100% and i get good frames, roughly around 70-90 but when i get to an area such as a fate that needs alot of ppl to complete (Svara) or when i enter a town such as revenants toll, the frame rate goes to s***, BUT so does the percentage of how much resources and the such the game is using on the Gpu. its drops down to 30-40 % usage like a cap has been put on automatically depending how many players are in the area.

This cap is active when you start to here the mass player sound effects such as the chattering and the war cry's and all. Is there anyway to turn this automatic cap off so the gpu can use 100% so the frame rate doesn't go to the shi*s during these situations?
