Doom timedemo 3 on an Amiga 500

If this doesn't work on real hardware, I blame the upload date. 😛

In this version, all enemies are Spectres.

good job! though shouldn't it (theoretically) be running as fast as the Mac Plus version, seeing as they are running on the same CPU with a comparably similar video mode?

[@DookNookim]

The Macintosh version reaches 2 frames per second, the Amiga version 2.5 frames. The Amiga version is faster because it uses double buffering and page flipping, and the vertical resolution is half of the Macintosh resolution.

@@DookNookim huh good to know. i wonder if Agnus could help with doing some of the UI stuff and border

@@shadowchasernql The demo uses two screen buffers. When the status bar changes due to receiving damage etc., it's converted from 256 colors to 2 colors and drawn on to the first screen buffer. And then the Blitter is used to copy the status bar from the first buffer to the second buffer. I've tried not drawing the status bar, but that hardly increases the frame rate.
