This is my first post here and im making a PSX-style game.

I'm very divided on something - do i make the game in a high resolution but use a filter to make it look pixelated or do i just put it in a low resolution like 320x240?

This is not a "correct or wrong" question. I'm just curious on what gamers think is best.

I don't have much experience with the PS1, besides a couple a games like Silent Hill, but both options might work just fine. The low res one will likely be faster due to not rendering extra pixels, but I don't think it will make much of a difference in speed due to the style being low in system requirements.
