ThreeSon: The last time I tried my disc version of The Suffering a few years ago, there was some pretty bad texture problems where garbage would cover the screen at certain moments. Specifically, in the opening jail cell, if you look at the toilet and flush it, the whole screen glitches out for a second or two.

Have these games been updated at all or are they just straight ports?

Darklord666: I can't remember this glitch in the past and now I haven't experienced it.
But there are graphic glitches later in the game.
Especially when you're in the courtyard of the prison! There were textures on the floor missing in the past and that is still not fixed.
