Hi. What is the limiting factor in this game, what can I do to increase performance? I get horrible slow-downs and stuttering here and there and especially when jumping or hitting an enemy. I tried setting EVERYTHING to as low as it went and it did have an effect, but only a reaaaally small one.

Personally, I don't think a game like this, and looking like this should stutter on my rig at all.

I have a i7-4790K @4GHz, RTX2060 6Gb, 16Gb DDR3. Game is installed on an SSD, but it shouldn't matter anyway if I just stay on one screen.

I get random stuttering as well. Did you try maybe turning off v-sync and frame smoothing, and seeing if being fullscreen or not makes a difference?

So I think I found a fix:

1.Delete the system data save file. It's located in appdata/local/Bloodstained/saved/savegame
It's a hidden folder so make sure you have hidden folders viewable. I simply removed the System_slot.sav and kept my story saves.

2.Start the game up and go to Configuration before you load any saves. Turn off voices by lowering the voice volume to 0

3. Load a save and you should be free of stuttering. DO NOT turn voices back up! It will start the stuttering again. You'll have to play without voices till a proper fix comes by. There's probably a bug or memory leak in the system save that causes this.
