Re: i7-3540M or i7-3632QM better for PCem performance?

PCem uses several threads:

- one for the CPU and sound emulation
- one for the video emulation
- one/two for Voodoo emulation, doubled with SLI enabled

Re: Thank You SarahWalker for PCem

Pretty much all of my early computers (long dismantled since) have been recreated in this pretty well, save for a couple of specific ISA/PCI video cards and boards (one of them's a MegaPC just for the familiar Phoenix parts for an unrelated US OEM currently undumped, and the M919 isn't there as the ...

Re: PCem starred in my retrobattlestations contest entry

It *might* be possible to do a (forbidden, unsupported) DOSBox 0.74 Win95 guest to run DOSBox 0.74 with that emulator in there within a PCem Win98 guest. (Maybe, at the highest K6 you can run) There's also the old "dosemu" to consider on the Linux guest side. oh how I don't miss those old "dosbox po...

Re: [Patch] Intel PIIX3 southbridge (including USB controller)

USB passthrough would probably be a huge headache for platform support. I can see it being a big benefit for emulating the better USB version of the Interact Hammerhead (vintage and close enough to the typical modern gamepad and carries the 3dfx brand cult appeal), as the gameport version drivers br...

Re: Most affordable CPU to emulate the most powerful CPU without stutter?

In reality though, about *all* 1997+ 3d cards are "bottlenecked" by the CPUs of their time; the Voodoo2 just gets added mysticism because of certain high benchmark numbers from simpler looking games *cough*forsaken*cough* from certain enthusiasts because it makes the Voodoo2 look like it ages well (...

Re: Most affordable CPU to emulate the most powerful CPU without stutter?

An intel Core something beyond 4.2GHz after 2013 should be enough for the PMMX233 stuff.

Re: PCem infrared emulation

You've got to look at it from a practicality standpoint. Console/handheld emulators emulating IR is more important for functionality than how infrared was for PCs as there's plenty of games that rely on IR functionality (i.e. for linking, wiimotes etc). PCs weren't the same. There's probably some co...

Re: Future graphics card emulation

Probably because it's not worth the effort for all the funny wonky affine texture mapping the Laguna3D's notoriously known for. That's all it would lead to. No further video cards could derive off of that point. Direct3D support is common with about every 3d card already listed, and basic support of...

A HLT-spamming "cooling" tool like Rain and Waterfall should help. Remember that in Win9x at idle, old processors were constantly loaded which doesn't get along with PCem's dynarec.

Re: Future graphics card emulation

I had a Rage Pro somewhere. I recall it did alpha blending through software and it'd look noticeably noisy (especially in motion). The GL ICD on the last driver would bring flashing textures in idTech3 stuff. Turok looked awful.
