Doom port for DOS, based on PCDoom by @nukeykt. The goal of this port is to make it as fast as possible for 386/486 personal computers.
- Added FPS ingame viewer
- Added FPS calculation after timedemo runs
- Added option to render visplanes (ceiling and floors) without textures
- Added option to render walls without textures
- Added option to render Spectres and invisible objects like real transparent objects (harder to see, a little faster to render)
- Added option to render sky as a flat fixed color
- Added option to render Spectre and invisible objects like the Sega Saturn port did
- Added option to render Spectre and invisible objects like Heretic/Hexen
- New option to show only objects that are not far away from the player. All the enemies are still rendered as they're important
- PC Speaker uses all sounds available (just for fun!)
- New mode for PC Speaker (digitized sound!)
- Disney Sound Source support
- COVOX LPT DAC support
- Adlib OPL2 PCM support
- OPL2LPT and OPL3LPT support
- Tandy 3-voice PCM support (SN76489)
- Creative Music System / Game Blaster support
- Audio-CD music support
- PCM music support (through sound fx device)
- Hercules automap support
- 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). Much faster rendering, specially on 386 cpu's and slow 8-bit VGA ISA cards.
- Better use of system RAM (full memory allocation)
- Removed network gaming support
- Removed joystick support
- Removed Y mouse movement (move forward/backwards)
- Added autorun support (F12 key)
