I could have gone with the 486 in place of the Pentium to attempt to reduce the load on the host CPU, but the BIOS of each 486 motherboard emulated by PCEM didn't show/detect the CD drive.

I can't find the option to disable SMT in the BIOS of my Dell Inspiron 15 laptop.

Maybe Windows 98 more demanding than Windows 95. I might consider turning off SMT, but does Windows 11 require SMT?

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 ...

Would a different motherboard (for emulated systems) impact performance as well?

So do I have to turn SMT off when using PCEM?

You mean when SMT is on, it negatively affects performance?

My number of logical processors are twice the number of cores. How can I find the render driver that I'm using?

While emulating both CPUs, the percentage is mostly in the range of 70%-100% and it rarely got higher than 100%. While running the game, the percentage dropped below 70%.

Make sure that you are not running any applications that take too much CPU resources. As suggested before, the power plan settings shall be set to maximum performance mode and let the laptop be plugged in the whole time when using PCem. The only power plan I can find on my laptop is Balanced, so I ...

Try, for example, any of the first five Need for Speed games to see if it makes any difference.

I meant what OS for your emulated machine.

So how do I reduce the load on my CPU? What OS did you try the games on?

I'm using v17. Windows 98 and the games I run on it (including Putt Putt Joins the Parade and Magic School Bus Explores the Rainforest) gave me problems.

I did use CPUs lower than Pentium 200 from Pentium 75 to Pentium 166 but they have similar results (awkward video speed and audio glitches).

So are you suggesting that I have to use a CPU with slower speed for my emulated machine?

On my Acer laptop with i5-10210U processor I was able to squeeze out more performance from PCem by switching the Windows power plan settings from "Balanced" to "Ultimate performance". Make sure that your laptop is plugged in the whole time when you use PCem. Did Ultimate perform...

It sounds like you're thermal throttling because that chip should be capable of up to 4.3Ghz

How can I fix that?

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

I have Windows 98 installed at the emulated machine. The motherboard that I'm using is Shuttle HOT-557. I'm also using Sound Blaster 16 and Phoenix S3 Trio64. Every time I try to play a game on the emulated machine, the audio glitches and skips. The video plays at an awkward speed level because of t...

That means I can't make pdfs from files on the emulated machine either, especially the ones printed from games.

I'd like to have PCEM print from an emulated machine directly to a host printer. I saw that some PC games and applications can print files via printers.

I wanted to print a file from the emulated machine on PCEM v17, but I don't know what printer PCEM emulates, and I can't find any printer options for printing to a real printer. Can PCEM emulate printers?
