This is not a generic performance problem stemming from demanding graphics. The issue is tied to a specific bug triggered in that particular area, causing the game to stutter and slow down drastically until the player limps through the mission.
Which released your version (e.g., FitGirl, ElAmigos)? Your graphics card model (Nvidia or AMD)? The exact operating system you are running?
