I have noticed maybe the physx collision is a tad iffy!
Doing a project of my own,i noticed stuff going straight through walls on a certain angle, looking into it i noticed also that the example in projects\dark physics\demos\ragdoll\shooter also has the same affliction, on a certain angle the balls go straight through the floor!

Hail to the king, baby!

Have a look at the CCD commands. They help stop objects tunneling through other objects.

There are a few tips, here, but this is a general issue for ALL physics engines.

1. Have walls that are thick. Makes it easier for the engine to approximate a correct solution; objects caught "inside" the wall will bounce back out.

2. Look into the continuous collision commands; CCD, as suggested by NickH.

3. Make sure that you don't apply insane forces. Using physics to calculate projectile movement, for example, is NOT a good idea.
