Random Overture Slowdowns?

[alucardwcd]

So I renamed /lib to /lib.bak and filled /lib with symlinks to my system libraries. libCg, libCgGL and libfltk are not available to me as 32 bit through gentoo, so I reused the stock libfltk and downloaded libCg/libCgGL from nvidia's site. This did not fix the problem, however when the slowdown occurs it no longer drags the esc menu down with it, so I can actually quit the game.

For example, I previously explored shaft 12, and then subsequently shaft 13 in Chapter 3. I then found it necessary to return to shaft 12, but upon entering the door to 12 the game instantly drops to 1FPS at which point I have to just quit. Up until this point I have been able to fix these slowdowns with a mixture of game restarts and playing with the game video settings, but this has been unsuccessful for this point and I cannot advance in the game.

The game runs perfectly smooth at highest detail until these slowdowns occur btw.
