Is there a reason for this, something being bottlenecked somewhere in the game engine? For example on Borderlands 2 I have set the FPS to cap at 120, yet a lot of the time it hovers around 100FPS with only 40% of the GPU (RTX 2080) in use and only 30% of the CPU (i7 9700k). Its the same on Elder Scrolls Online, sometimes it dips below 60fps in heavy action scenes despite the fact its only using 40% of the gpu. VRAM isn't an issue either, both only seem to use 2gb, leaving 6gb spare. Temps are also fine with the GPU hovering around 58-60C I also have 16GB of RAM.
