IIRC the "Voodoo Series" drivers from late 2000 has issues with VB/V3 and drivers from earlier (late 99/early 00) should work better. 3dfx pulled an nVidia with regressing prior hardware in driver updates :( any specific examples of that? the final drivers for V3 worked well for me so far and the …

the CT2230 has jumpers to set the i/o ports (by default 220h for the SB16 part and 330h for the MPU-401 part), while DMA and IRQ are configured in software. if you reboot from win95 to DOS you shouldn't have to do anything, provided your SET BLASTER line in autoexec.bat matches whatever resources …

it's probably best practice to always run aweutil /s before any game, given the quality of some of those drivers... if anyone wants to hear some real "advanced" effects, try running the music test in descent 1.4a setup (or maybe any version), then doom2 with AWE support, but you might want to turn …

i've recently come to notice that just running CTCM is not enough to make the AWE32 music option in games play on the CT4520, despite it saying that 3 devices were configured. while it does appear to play (no "no sound driver" message in descent setup, which appears when the card isn't initialized …

one aspect that i don't commonly see mentioned is that the isa pnp initialization in bios was a practically pointless addition, at least for sound cards, because if you take AWE cards for instance, it only initializes the sb16 part but not the AWE synth. there is no reference of what resources are …

my CT2290 (V4.13 CT1741) definitely has the bug in doom engine games and on some maps it occurs often enough to be annoying, i have a worst case example as well in case someone wants to verify: doom2 map14. this weird loud square wave at the very end often gets stuck at the loop and the following …

well you haven't mentioned anything about the first notes after the loop being played too quickly, you just said it's skipping some silence at the end. your example matches the issue i mentioned in my previous post, i have also checked it in dosbox (old 0.74 version) and it's somewhat present there …

what makes you think that that particular track should have silence at the end? there is some kind of OST version with extra reverb on youtube that does, but ingame i don't get the silence either. or maybe it differs between versions of the game, because the audio driver changed over time as well. …

cB1 and cC has the new 350 nm process (3,3V). B5, C2 and E0 is the 600 nm process. Pentium 120 with 600 nm has a TDP of 12.81W, the 350 nm version has a TDP of 10,2W.

yes, that would explain the difference - so then it would be the other way around and they tried to compensate for the presumably lower quality textures in glide by running a negative LOD bias. could this be a case of 8-bit paletted texture usage reducing the quality in glide?

well, if you're inclined you could try to dial in a value that will make the D3D renderer display similar faraway texture detail as in glide and post another shot of that pond. apart from running SSAA negative LOD bias settings usually aren't useful, due to the shimmering they cause, but if a game …

i was about to say it's a texture LOD difference, as it's pretty clear the glide shots exhibit more texture detail far away, like on the ground on the other side of the pond, and that would fit with what you tried to describe as a "lighting box" (which would be mipmap banding). however, looking at …
