Re: CD-ROM drive not appearing in Windows 95?

This happens when something confuses Win95's IDE controller device drivers (like changing motherboards), try removing them and restarting a couple of times to redetect them. If that doesn't work and you're really desperate, you might want to try a real-mode driver (of the mscdex + oakcdrom/nec_ide.s...

Re: PCem v17 running slow/lagging

The AMD K6-2 has 3Dnow! extensions and 3dfx Voodoo2 and Voodoo3 drivers after 1999 can take advantage of them for performance gains (which can lead to heavier emulation). The achilles' heel is the VIA MVP3 chipset on the actual boards (historically, they'd skew agp compatibility towards 3dfx cards a...

Re: Close PCem after Windows Shutdown

If you've started PCem with the --config parameter, and the guest uses a newer APIC supported motherboard and Windows 98+ is configured for that, then it should completely exit.

Re: Trouble Installing Win98 PCI-128 Drives With Epox P55

Win98SE doesn't come with any AudioPCI 128/ES1371/ES1373 drivers (win98se drivers are generally current to Dec 1997+DirectX 6.1). They started adding those in Windows 2000 and Me. Also remember, if something's asking for the Win98 cd, you'll want to correct the path to read D:\WIN98 rather than the ...

Re: Maximizing PCem performance

When V17 came out with the official tuned build, I made myself a spreadsheet table of all the CPUs I can benchmark for 100% execution with a Voodoo Banshee using the second (visible) half of MDK2's benchmark and standing in place on Q3DM17. This was enough for my general use cases. (My fastest 100%'...

Re: [Patch] Voodoo 3 WinUAE merge notes/patch

Re: [Patch] Voodoo 3 WinUAE merge notes/patch

I wonder if this emulates Amiga's terrible Quake2 performance with one of those (where there's a vertex lighting hack that doesn't really help matters IIRC). I can't imagine the bus being too great for 3d acceleration (akin to using a laptop's docking station)

Re: Voodoo 2 Total Memory Size?

Just know there's many older games that don't understand multitexturing/second TMUs and effectively use the V2 as if it were a 4MB Voodoo1 card. The number is also consistent with driver's control panel itself. There's a checkbox to restrict the texture memory to 2MB (for the 4MB tmem models) to reg...

Re: Voodoo 2 Total Memory Size?

The option's there for curiosity (a 2mb framebuffer Voodoo2 would've been for arcade machines) A Voodoo2 always have two TMUs, and that chosen texture memory will be multiplied by 2 always on the Voodoo2 option. Same goes for the Obsidian SB50 above it. Consumer V2s always had a 4MB framebuffer, and...

Re: Voodoo 1 vs. Voodoo 3

Even at that speed, there will be performance differences from the multitexturing capabilities and fill rate alone. Also the greater amount of texture memory on the Banshee and Voodoo3 will make for far less thrashing (especially against a "24MB" V2SLI) A good place to show the Voodoo3 off is Quake3...

Re: Game Terracide won't recognize 3d card in pcem

Well.... there's no texture corruption on the VG emulation, and the Voodoo Graphics is still multitudes faster than a ViRGE. Whether it's worth the trouble to play Terracide itself is up to you. Dealing with a little driver shuffle is mildly inconvenient compared to playing Terracide.

Re: Game Terracide won't recognize 3d card in pcem

Does something "bad" happen if i just switch from voodoo 2 to vo0doo1, driver wise? It won't initialize the card and will just annoy you with warning popups.

Re: Game Terracide won't recognize 3d card in pcem

Given the poor reviews it had, I wouldn't doubt they'd have some hacky voodoo secondary D3D device detection routine that isn't futureproof for recognizing '3dfxv2' in 1997 (much like Jet Moto). V2 drivers work slightly different to V1 regarding D3D HAL behavior though... On the other hand, it does ...

On the SBLive emulation, should it ever happen, would it also emulate the performance penalties?
