Thanks for the clarification. I should also specify for clarity that the modified v11 here isn't based on the release but on an interim version off the repository from around october last year. I'm fairly sure however that I removed the videomemory flag off the release version source as well, and …

My observations of running pcem for win v11 in wine 1.6.2 on ubuntu 16.04. See reference video there. If legally possible, obtain a local copy of the video for continued access. https://www.youtube.com/watch?v=K4KvWN6Ov1s Immediate issues: - release version crashes, modified version runs - …

Hence my case for mending the windows version.

I don't have the modified source handy, but I'm guessing it was the DDSCAPS_VIDEOMEMORY flag in ddraw_init() (win-ddraw.cc/win-ddraw-fs.cc) that had to go.

Last year, I tried to run pcem v11 for windows in virtualbox (linux host, windows guest), and it crashed on launch. This was easily fixed in the pcem source by removing an initialization flag off a pixel buffer. The details escape me now, and in any case I don't know the implications of this fix for …

RallySportED, the only known publically available track editor for the cult DOS game Rally-Sport. (Only supports the game's demo version.) Implements a 2.5d zarch-like engine to mimic the game's, though no polygonal objects. Runs in DOS and certain flavors of Linux. Target audience: creative DOS …

What was the market share of agp motherboards in 1998? Mine had no such thing then.

My creative (msi?) 2 ti came with vram rated for ultra speeds anyway. Not with ramsinks though.

Earlier, I had a look to see whether it's usual for manufacturers to provide end-user programming interfaces to access their capture cards' output, and it seemed to me that it was. Therefore, and given that there are such capture cards on the second-hand market for not much money that also handle …

A vga capture image quality comparison between the voodoo 3 and geforce 2 ti with the visionrgb-pro. Windows desktop, 640x480, and brief outcast gameplay, 320x240. The capture card appears to output 320x240 as 640x480, but requires tweaking the phase setting from 640x480 lest artefacts appear with …

Wrote a program, vcapturescaler, for the datapath visionrgb-pro card to do better-quality capture than what you get with the datapath viewer. https://github.com/leikareipa/vcapturescaler So is this a problem with your capture solution or a general issue with the Voodoo3 ? I can not remember having …

It's the agp version. This particular phenomenon was a phase issue, easily suppressed: https://www.youtube.com/watch?v=nkfsZYzGN_g. It's not fully eliminated in that example, but it seems possible with some tweaking.

Some vga test capture with the old datapath visionrgb-pro and a voodoo 3. Vga mode 13h: https://www.youtube.com/watch?v=zj8z5D9bGdE Dos text mode: https://www.youtube.com/watch?v=2dFnF2YtRbU The datapath card is fed via pci passthrough (vfio) from ubuntu 16.04 to a windows 7 guest in kvm, and …

Booting the pc after a few days gave a blank screen on windows' desktop, rebooting gave a cursor and some corrupt icons. This was running the v3 at 92 mhz. I suspect an inverse relationship between temperature and minimum mhz here. Didn't perceive errors once it was booted at 100 mhz. Measured some …

The practical value of underclocking the voodoo 3 here is a ca. 10% reduction in temperature at no cost in performance, given certain hardware and resolutions. You can relate this to the 10% or so increase in performance many people are content with from overclocking their hardware, something that …

As to what limits the underclock, I'm only guessing, and with a sample size of one, it's especially hard to guess. This particular sample says that below 92 mhz (reported as 93 mhz by the 3dfx info screen), screen corruption occurs, and below 85 mhz or so, a blank screen.

Can't desync core and ram frequency on the voodoo 3 as far as I know. 3dfx's own overclocking utility, at least the one with v. 1.07 drivers, won't let you go below 100 mhz, not sure whether that's arbitrary or a general limitation of the hardware.

On a K6-2 300,* the Voodoo 3 2000's performance is bottlenecked, as is common knowledge. At resolutions up to 800x600, the game Need for Speed 5 (below) at medium settings is capping at an average of about 35 FPS running a 120-second replay of a race on the game's first track regardless of whether …
