Description Zach Kelly 2011-12-15 22:24:40 EST 
I have been getting minor to major fps drops/lagging/skipping in the same areas every time.
Minor occurring with fans, such as jumping over the gap in 2-5 (The Big Empty), and CHAD, when the screen moves up
Major occurring whenever there are a lot of locks are being unlocked, making levels with them nearly unplayable, leaving a lot of things up to luck.

This bug can be seen in this video: http://www.youtube.com/watch?v=3NCDoMjqMoU

Note how it only happens when the player is at certain areas in the level.
Also affects other characters I have unlocked.

This makes some parts of the game truly unplayable.

I noticed I have the same bug as shown in your video (Level 2-11) when I get the key, I get major lag.

I just reported this same bug as bug 5738, and somebody commented, there, suggesting that I check here. In my own bug report, I explained that I can circumvent this lag by turning sound effect volume down to zero, and so I believe that this is a bug with sound effects. I haven't tested this with the fan lag, but it resolves the "key" lag on level 2-11, which prevents me from finishing the stage, otherwise.

I hope that this bug gets addressed soon, but, in the meantime, I suggest that you turn off the sound-effects for levels that are too laggy to finish otherwise.

Confirmed to stop when sound-effects are turned to 0. This includes fans

I had the exact same issue (frame drop in 2-12 made the level unplayable). I confirm that disabling sound-effects works. So, it made me wonder if it was not the fault of libopenal.

I removed the amd64/libopenal.so.1 file so that my system version of the library would be used instead and it completely did the trick for me. I can play with the sound, and have experienced no lag so far.

I gave the trick to a friend of mine and he confirmed that it also improves things quite drastically on his computer.

Regards,
Tony

This should be fixed in the latest Steam and Humble Bundle builds.
