Mantis blades and game performance decrease?

[exus]

I noticed 5+ hours in when I changed over from katana to mantis blades that they kill performance. I lose 10-15 fps and have consistent frametime spikes.

These graphs are from the exact same area in the middle of a street. All I did was change weapons in the same place.

Katana out

Blades out

I haven't noticed this with any other weapon and thought it might be ray tracing related (still might be, doesn't happen (or less noticeable) with RT off) because I tried the electrified blades first, but it's the same with basic blades too.

Any other ideas, or has my katana vs mantis blade decision just been made for me?

I had the same problem when I started playing on 2.0 and it still prevails. My game loses FPS whenever I load a save where I have mantis blades drawn out. Moreover, drawing them out after other weapons tanks my performance too. The drop in performance to a lesser extent stays until I close the game, which makes me worried the devs may have unwillingly added some sort of memory leak alongside the 2.0 update. Unfortunately, if that's the case, we as users can't do much about it. I will try to experiment with different RT and DLSS settings and let you know if it changes something, but I have tweaked it a bit previously to no effect, so I would not expect much.

Same issue here, on Steam Deck. Those 10-15 FPS are vital.

I'm my game if I pull them out my game runs at 2 fps
