I don't how easy this would be to implement, but it would be really nice if there was a hotkey to open a dialog to change CD images so you don't have to exit fullscreen to swap discs. Would be especially helpful for multiple CD games so you don't have you break the immersion factor when changing dis...

Yep

Discovered when having issues running the War in Heaven on a Voodoo 2 that even emulated the card goes nuts when you try and run a heavy game with a version of DX that doesn't match the installed driver. So latest VD2 driver + DX7 is the best combo.

https://i.imgur.com/uAzVsf1.png I was seeing how a P2 on my system could handle a realistically heavy load by opening a quicktime based sampler after even torture testing running Half-Life at minimum everything on a Voodoo 3 3000 to max frames only dropped emulation speed to 95%. I don't know what'...

Are there any plans in the pipe for speeding up or optimizing the emulation any? As of now even with CPU tweaks via a batch file (disabled SMT and forcing high-priority) I'm topping out at a Pentium II 233 on my 5600X and it would be nice if I could at least iron out the brief second of emulation la...

Navigate to the Video section of the PCem's menu which is right below its status bar. Here you will see an entry called Render driver. Try different render drivers to see which one works best for you. Another thing to try: in your Windows Task Manager navigate to the Details tab. Look for the pcem ...

My CPU is AMD Ryzen 7 5700U with Radeon Graphics @ 1.80 GHz. I have a RAM of 16.0 GB and my OS is Windows 11. I have a laptop. It sounds like you're thermal throttling because that chip should be capable of up to 4.3Ghz How can I fix that? There's not much you can do with a laptop unless you try ru...

It sounds like you're thermal throttling because that chip should be capable of up to 4.3Ghz, about enough to do a Pentium MMX 200

I used most Pentium CPUs and some AMD CPUs. What do you mean by "your PC specs"?

What Mike said

What hardware is in your actual PC you're running PCEM on

What are your PC specs and what CPUs have you tried to emulate?

R5-5600X (PBO enabled, all-core turbo of 4.5Ghz, single-threaded 4.6Ghz) DEEPCOOL GAMMAXX 400(With Coolermaster 120mm Sickleflow fans) 16GB 2400Mhz DDR4 MSI MPG B550 Gaming Plus Mobo RTX-2070 Windforce Full ATX Case with Dual Intake and Dual Exhaust Windows 10 Professional (latest update) Via gettin...

I had been vaguely pondering the idea of running the Voodoo emulation as a compute shader. Might be unworkable, but possibly worth considering for some point in the distant future. Might get PCEM up and running later 9x games on systems that are running fast quad cores and entry level GPUs that can...

I'd like to post a final update that using that "hack" of forcing PCEM to run without SMT I now have a Pentium II 233Mhz with a Voodoo 3 3000 running at 100% speed on an R5-5600X. I think I've discovered something beneficial here.

I've been using The Mummy: Return of the Pharaoh. The game uses quicktime video files for literally everything, so it hammers the virtual CPU hard.

In theory, your CPU should do at least Pentium II 233 if not 266 flawlessly considering that the upper limit of flawless operation on my i7 6700 non-K is Pentium MMX 166. I can play several games at 100% on Pentium II 233 and some 3D-accelerated ones (e.g. The Need for Speed III) work most of the t...

Ryzen 5 3500 U is unfortunately too slow for proper Pentium MMX 233 emulation which is why you're getting stuttering sound. Try selecting Pentium MMX 166. OP might be able to get away with a Pentium 200, that's the limit of what I could do on my 3600X and currently can do on my 5600X. 233Mhz is def...

So, I'm running a 5600X over here and I can emulate up to a Pentium 200 with a Voodoo 3 3000 flawlessly. However, when I try to step up to a Pentium 233 I'm noticing PCEM is actually leaving a lot of power on the table. My CPU can sustain a clock speed of 4.5Ghz all core when it's turbo kicks in but...

Good the see the project has found a new dev with Sarah's blessing and been resurrected.

I look forward to seeing what kind of improvements and features future builds bring

It sounds like you're describing a horrible complicated way of implementing a frame rate lock. Something that doesn't work because the reasons CPU speed can break old games is more complex than that. Like what happens in the 7th Guest where access to a CPU that's signigantly faster than it was desig...

Did you do some footwork to see if it's real behavior?

It's not many but there actually is a couple odd DOS games that pitch a fit on Windows 9x operating systems.

If you have a different bug, it is a general forum etiquette to make a different thread for it. "Windows 98SE Freezes" seemed in the ballpark to me =p A reboot freeze typically happens for much different reasons that freezes when playing specific games. OP of the thread here Stealth is we...

It's about experimenting and tuning to figure what CPU you go into most things without noticeable slowdown with. For me that's so far turned out to be a Pentium MMX 200Mhz on my 3600X that hits 4.1Ghz PBO all core. 233Mhz if I'm not planning on running anything that uses Quicktime that particular se...

Posted this in my thread as well but there seems to be a bug in the Socket 7 CPUs where they take a lot more host CPU than they should and lag when decoding Quicktime video of any kind. Pentium II/233 works flawlessly in Quicktime heavy games Pentium MMX 233 has noticeable slowdown and I have to dro...

Re: mouse: I ended tweaking the mouse acceleration options in windows 98 to the minimum. I am assuming that the problems are currently a double-acceleration caused from the real OS + emulated OS. Also, I am not sure if it is correctly compensating for high-dpi or fullscreen. (Never checked). Back w...

At a guess, probably the same issue as http://pcem-emulator.co.uk/phpBB3/viewtopic.php?f=3&t=3577 So I've done some testing and confirmed it's a problem with the faster Socket 7 CPUs. The Pentium II/233 works flawlessly in Quicktime content. The Pentium MMX 233 has noticeable slowdown in the sa...

Then how come the disc works fine when the installer asks for it on other motherboards?

I'm trying to use the Epox P55 motherboard to test something and ran into this issue where it can't find the drivers the Soundblaster 128 needs on the WIndows 98 SE ISO. This particular failure only happens when I try to build a system with this particular motherboard. The ASUS boards also get stuck...

Update again

It is not fixed

However with the fact it doesn't happen on the Pentium II/233 I can confirm it's a specifically with the MMX CPUs on Socket 7.

Here's configs from one of my machines, to.

The FIC VA-503+ is the one I happened to use but it was also doing it with the Gigabyte Slot 1 board when I tested a Pentium II.
