There are scenes that run at 20fps (in the new remaster mode) instead of 30 in the original according to Eurogamer. Sometimes the frame rate drops to 15 or even 10fps.
You can play the game also in the classic mode with no visual upgrades. Then the game runs like on PS1 with 30 to 10fps depending on the scene.
Even on a high end PC the game has the same performance issues, so the horse power isn't the problem. It looks like the game is emulated instead of remade from the ground up for modern systems.
Unfortunately it's another quick made remaster with a bit of a visual upgrade, but the performance disappoints.
