Bug for FDOOM2 (486) - start up Map01, kill some zombiemen on the stairs. Take out chainsaw and saw away. Bulletpuffs will appear in mid air when standing on/near a corpse.
Also music support for Gravis UltraSound appears to be broken.

Current Project: new GUS PnP compatible soundcard

I tested it and the problem is not with chainsaw and zombiemen, but with chainsaw and any stairs (use the chainsaw near any wall and it will show the bulletpuffs). Punch it's not affected by this bug. I tracked back this bug to version 0.66 and upwards, so i will try to fix it in the next version. It also seems to be only a visual problem.

Anyway thanks for reporting this bug!

Forgot to post this, I made some benchmarks with FastDoom 0.666 in one of my testbenchs.

FastDoom 386 build, Doom shareware 1.9 WAD, Demo3, default fullscreen + hud.
CPU: Cyrix CX486 33Mhz (8Kb L1 WB)
Mainboard: CH 498B (512Kb L2 WB)
RAM: 32Mb EDO
Video card: Generic S3 805i VLB (1Mb)
Sound card: None
I/O card: Generic IDE ISA
HDD: Generic CompactFlash 256Mb

Main conclusions:

  • FastDoom 0.666 is 20% faster in high quality, and 28% faster in low quality compared to Doom shareware 1.9 (fullscreen + hud)
  • FastDoom low quality is ~1.7 times faster than FastDoom high quality (fullscreen + hud)
  • FastDoom Potato quality is ~2.5 times faster than FastDoom high quality (fullscreen + hud)
  • Flatter surfaces isn't faster compared to flat surfaces with low quality and high quality. Flat surfaces gives 20% extra performance in low quality, and 17% in high quality. Flatter surfaces is faster with potato quality, giving 26% extra performance.
  • Reduced screen size gives an important boost
  • The other visual optimizations have minimal impact in performance
