I didn't know where to put this, but since Firestorm is in the AUR, I figured this was the best spot.
I'm having problems with extreme lag and freakishly low FPS that I have never experienced on Windows or LMDE. Firestorm support said it was probably related to my graphics drivers. Well, as far as I can tell, I'm using the propitiatory drivers for my on-board Intel graphics, so I'm not sure what is causing this. If I need to add more details, please let me know.
