Re: [Req] Creative EAX emulation?

Half-Life has its own reverb/echo DSP system fyi, so EAX isn't necessarily required. PCem would need the EMU8000 feature finished first, since Live is also EMU based maybe it could be jerry-rigged with the OpenAL EFX stuff in the meanwhile (it might require separate buffers for opl/midi/pcm/pcspkr f...

Re: Thank you! (Dithering)

That's right. 3dfx was also once in an ubiquitous state that 16-bit dithering/grain was a common complaint on anything that wasn't a 3dfx card (was well as the default gamma being kicked up to 1.3/1.7 on 3dfx, causing its rivals to be "too dark" when they're actually correct). The filter was definit...

Re: PCem Host System Requirements - Pentium MMX

Shock's one of those cache-heavy self-modifying code games that perform poorly in the V11 release. Try compiling your own from the latest tree and see if it runs better. EDIT: Thought it was shock 1, but still, the same advice applies. also it ran in the 20s-30s on Pentium II+V2s of its day so i'm n...

Re: Thank you! (Dithering)

A real voodoo wouldn't expose the dithering as pristine and intact in the screenshot though, as it had a undithering filter on the DAC which gave 3dfx their characteristically blurry/waxy look. You'd only usually see those unfiltered, dithered pixels in windowed mode on a Banshee/V3/V4/V5, or screen...

You don't. Both emulators are misleading (with the "better" marketing and its "beta forum" fan club to echo that) and bring false expectations and inaccurate bug reports towards PCem, and thus neither are supported here.

Re: Development on Voodoo2 or 3 and OpenGL output.

I see it feasible as well. It's more similar to a Voodoo Graphics (no multitexturing) but with a decent 2D core this time around (unlike Rush), and much stronger Windows driver support (also including third-party drivers) also like all of the newer Voodoo cards it can do 3d from 320x200 to 1600x1200...

Definitely not on any Infinite cache setting. The Voodoo recompiler should be fine though

At the time of this writing, an i5 (i7 on laptops) @>4ghz should get you to PMMX166 Infinite nicely.

You'll also need to install 3dfx drivers ( here is a nice page of various drivers , stick to V3.01.00). Also 3dfx shouldn't discriminate the video card (as long as it supports DirectX for setting video modes and 16-bit color IIRC) And if you need "proof" of 800x600.... here is a relatively more adva...

Cross the 4ghz mark with it and you should be sailing in the PMMX166 infinite territory at least. Self-modifying code (i.e. Eradicator) will still be very slow however

Unsuccessful because i'd need to work with two lines, and the threaded lines makes this impossible. 2x2 would be best for a proper post shader system instead

That's to be expected. The SVGA drivers aren't supposed to be compatible with everything. On a real PC i've only had the SVGA driver work on Tseng and Realtek video cards, in my experience ~93-94.

Re: [PATCH] Fake Cyrix 6x86

FWIW my models list was based on what I saw here. The earlier 6x86 models definitely did have an identification issue so it's not expected to have XP (or even Windows Me) working on them. You can't install Creative's WaveGuide on them either.
