Yeah something is very wrong.
Standing at the second shrine, and at 1080p "Max" settings in windowed mode, I'm getting a fluctuating 50-55 FPS with the following specs:
i5 4670k
GTX 1080
32gb RAM
Windows 10
GPU sitting at 50% utilization and CPU at around 60% utilization.
Edit: While there's still definitely some weird fluctuations going on, disabling fullscreen optimizations and then imposing a 60fps framerate cap with RTSS have led to drastically more consistent 16.67 ms frametimes.
