Re: DOS32AWE - DOS/4G compatible DOS Extender with Sound Blaster AWEUTIL MIDI synthesizer support for Protected mode,V

Posted on 2021-10-06, 12:25

The game is obscure because it is extremely buggy. Of course, it does not use expanded memory at all (try EMS:N qemm parameter) so it is unclear what it needs (ironically the Asian readme tells not to worry about the memory). Several possibilities come to my mind -- it needs more conventional RAM, …

Too bad, but thanks for testing! Instead of spending time on DOS Glide further, I looked into making the 320x200 VGA mode faster by implementing a small rasterizer of my own instead of relying on OSMesa. A quick test in DOSBox gets me ~ 3x the performance in the title screen, in-game it can also be …

Ok, here's one last try. This removes the SB code and the interrupt 1C (timer interrupt) handling, so has a fixed time step (10 ms per frame hardcoded), and no FPS counter (as this relies on measuring time). Input handling is done via kbhit() and getch(), so no fancy keyboard interrupt hooking like …

and with any luck, Gmlb256 could have just had the splash screen disabled via environment variables, seeing that it was always a black screen there You guessed it right that I have disabled the 3Dfx splash screen by setting FX_GLIDE_NO_SPLASH to 1, I just like to get the game started already as …

What are the system requirements? Tried it with a 486/66 and got 1 fps. Tried also with univbe but couldn't get the vesa modes to run. I've feared that it would run much slower on such CPU considering the FPS I got, UniVBE won't improve much on that situation. Also certain older video cards doesn't …

It might be that the statically linked Glide 2 kind of requires a Voodoo 1. Have you tried setting environment variables similar to what made the Tomb Raider 1 3Dfx DOS version work? See this posting here: https://www.vogons.org/viewtopic.php?t=52516 (SST_GRXCLK, SST_FT_CLK_DEL, ...) I had set …

in Windows
There are some parts in SIGIL where you will experience slowdown even in 320x200 on DOS, I witnessed that on a P233MMX prior upgrading.

i think that this machine is a little bit overkill for fast doom, why not use the standard dos versions on dos mode, or in windows they should work too FastDoom is also faster for that kind of machine than the vanilla executables. You can see the benchmarks that I did with a K6-2+/450 CPU here . …

Nice arcade game! Tested it on a K6-2+/450 computer with write combining enabled and got around 27-29 FPS average in-game on 320x240 32bpp in DOS. I got some feedback: The 3Dfx version didn't work for me and froze the computer with a black screen with a single Voodoo2 12MB card. Video modes above …
