Re: Problems with some Origin games

I don't use a starter pack; just a stock 6.22 install + the official Creative Sound Blaster 16 floppies from 1993, which install a bunch of devices and TSRs to initialize the card and mixer. It's a little more involved than a simple SET BLASTER line.

Re: Problems with some Origin games

Just tried your config with a DOS 6.22 + SB16 drivers + OAK CD HDD image and the intro+game sound works there too.

Re: Few newbie questions

Until I noticed I can't run the slowest MMX even in W98 desktop for some reason, which I find really odd (opening windows, navigating, etc) makes it all drop below 100%. They'll all do that at startup on the current recompiler. I found running Rain helps a bit (your preference on HLT-spamming win9x...

Re: Voodoo2 on Windows XP

I never said it didn't work at all. It still has Glide support, just no Direct3D HAL driver. 3rd party drivers are your only option because, well....... 3dfx closed a year before XP released :roll:

It could happen eventually. There are bits of code in PCem already to support 387 detection. But "should" I wouldn't think so.

Re: 3DFX compatibility list

Yes. PCem doesn't frameskip. That triple core Athlon II won't give you much V2 SLI action. I'd expect it to only ever do well with Pentium 75. To get V2 SLI going great you would need a relatively recent Intel Core i5-i7 @4GHz+.

Re: 3DFX compatibility list

Unreal runs fine (and better starting from version 218). It's your host computer that's slow and can't handle all the frames at once. Adding (actual) Pentium II emulation won't fix this for you. Perhaps there's also a generational issue with regards to performance acceptance as well, as getting 25fp...

Re: [Patch] 3dfx rendering accuracy

I assumed the 3dfx V2 driver already dioes validating as i've managed to make the card detection fail while trial-and-erroring very slightly different dither tables. I don't have doubt for PCem's current 2x2 table. I would guess you are missing the conversion to RGB565 that is done after the ditheri...

Re: CD rom images will not load and freeze the GUI

I'd assume this is the WX mouse locking problem with the window focus, reproducible by doing this:

- open a CD-rom or shader manager window
- Tab to another window
- Close another window
- Witness your mouse get stuck in the center of the PCem window

Re: Having trouble installing Windows 98 SE

Sounds like 430VX - Try going into the BIOS and enable "reset configuration data" in the PNP/PCI config screen. Sometimes that'll get around a freeze on post. It's also important to have absolute paths to your hard drive images and CD-ROM image. and finally, not all 98SE CDs are bootable - only the ...

A lot of the special OEM machines PCem emulates also emulates their built-in video chipsets that sometimes doesn't have separate selectable emulation or have quirks/features of their own.

Here's a naive attempt at recreating the double-sized dither, which apparently only should apply to the 4x4 dithered triangles when they are blending (2x2 dithering, mostly seen under 3dfx's Direct3D HAL, and UnrealEngine should not be affected by this patch at all).
