Though I did notice traversal stuttering when I played Silent Hill F, the biggest technical issue I had was unrelated to the framerate. On a semi-regular basis I'd see everything suddenly shrink to fit the top-left quarter of the screen, except for the UI, with a flickering smear of colors filling the rest of my view. Others on the team didn't experience this bug, but I saw it pop up all the way through my time in haunted Ebisugaoka.
Turns out my habit of switching off motion blur without even thinking about it whenever I see it in the options menu is the problem, which I wish I'd known 20 hours ago when I started the game. Leave motion blur on and apparently you'll never experience this particular glitch.
