The Impossible Lab.

Just now the Lab is for me Impossible to complete...
i dont have the best pc/wlan so there are Fps drops.. thats okay
But the lava riddles are just now impossible to play.. after 4 seconds when i see the lava on screen the fps drops to 0 abd for 20 seconds i ca do nothing.. and the game crushed(log in screen)
In the first days in the lab the fps drops "just" to 4-7 fps..
i am so lucky i dont play Hardcore._.
