Hookshot version

v2.1.0

What kind of problem

Low fps or stutter

What happened

the game runs like a dream with occasional stutter, with my average FPS at 60-80 no FG.
Assuming that DLSS 5 usually only cut 10- 20 fps, I was expecting around 50-60fps, because even on an emulator where the average FPS isn't that high, DLSS 5 runs smoothly at 45-55 average.
But when I run the FPS sits around 20-40, barely reaching 40 most of the time, the CPU and GPU utilization is starkly underperforming; on a vanilla run it utilizes 70-80%, but with reshade/DLSS 5 on, it sits at around 50-60%, for both CPU and GPU

Where in the game

I'm on the newest release, or the problem is still there on it.
I searched the open issues for this problem.
I'm not attaching game files, keys, hookshot.exe, the .bin caches or saves.
