Re: Audio Glitches and Awkward Video Speed

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 ...

Re: Audio Glitches and Awkward Video Speed

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...

Re: Running PCem emulation in GPU

Might get PCEM up and running later 9x games on systems that are running fast quad cores and entry level GPUs that can...

Re: Weird Zen 3 Behavior

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.

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...

Re: Stuttering sound in Win98 machine

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...

Weird Zen 3 Behavior

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...

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.

Re: Maximizing PCem performance

It's about experimenting and tuning to figure what CPU you go into most things without noticeable slowdown with.

Is sub-par FPS on Some 2.5D Games Normal Behavior For a Voodoo 3?

I'm running an MMX 233 and a Voodoo 3 3000.

Some 2.5D games like Outlaws and Doom 95 have surprisingly mediocre FPS on anything much higher than 320x240 and I was wondering if that was normal for the hardware or a PCEM bug.
