Is anybody else experiencing EXTREMELY low-fps in the Red Square level of Metro: Last Light? The game was running smoothly with all max settings and SSAA until I got to this section. FPS has literally tanked to single digits and is completely unplayable now. It only started happening in this section and lowering the resolution and turning off SSAA and everything else makes zero difference in performance. This seems to be either a major bug in the game, or we need a new driver for Metro LL asap.
