Doom port for DOS, based on PCDoom by @nukeykt. The goal of this port is to make it as fast as posible for 386/486 personal computers.
- Added FPS ingame viewer. Enabled with "-fps"
- Added FPS calculation after timedemo runs
- Added option to render visplanes (ceiling and floors) without textures. Enable with "-flatsurfaces"
- Added option to render Spectres and invisible objects like real transparent objects (harder to see, a little faster to render). Enable with "-flatshadows"
- Added option to render sky as a flat fixed color. Enable with "-flatsky"
- Added option to render Spectre and invisible objects like the Sega Saturn port did. Enable with "-saturn"
- New option to show only objects that are not far away from the player. All the enemies are still rendered as they're important. Enabled with "-near"
- PC Speaker uses all sounds available (just for fun!)
- Lot's of optimizations to make the game run faster / smoother
- Removed low memory limit (may cause crashes with low RAM)
- NEW DETAIL LEVEL: POTATO. It renders the full scene with a quarter width resolution (max 80x200). 16-bit ISA video cards can play the game full screen much better!! My Western Digital Paradise PVGA1A ISA (1989) can render the game at a constant >25 fps with a 486DX-50. Enabled with "-potato" command parameter and low detail enabled.
- New option to allow more than 8Mb of memory allocation. Enabled with "-ram"
- Removed network gaming support
- Removed joystick support
- Removed Y mouse movement (move forward/backwards)

FastDoom 0.3 Live Demo:
FastDoom 0.2 Benchmark Demo:
- Get more FPS! (assembly, optimizing loops, etc)
- Add option to remove long dead monsters, as lesser sprites are faster to render
- Add option to render up to X distance
- Rewrite sound library (lump cache is not working right, all sounds are being uncached after 0.4 seconds of not being used, which causes major stutters)
- Add uncapped framerate support (up to 70 fps)
- Add a realtime performance viewer (FPS, frametime, total R_DrawColumn and R_DrawSpan calls, ...)
- Add more drawing modes (VESA?, linear VGA?, ...)
- Optimize drawing engine (front to back renderer?, ...)
- Install Open Watcom C version 1.9.
- Install Turbo Assembler 3.1, which is distributed with Borland C++ 3.1 (1992, not compatible with x64, use DOSBox or a real DOS environment).
- Add Watcom's bin folder (binnt on Windows, binw on DOS) to the PATH.
- Run make.bat.
