 **-f renderfile**: Render each frame to **renderfile** in addition to the screen.
 
-**-H**: Launch a HUD with running timers for each demo. This HUD can be moved or closed with the mouse.
-
 **-k**: Inhibit use of the alternate screen. Necessary if you want the output left on your terminal after the program exits.
 
 **-c**: Do not attempt to seed the PRNG. This is useful when benchmarking.
