Just one or maximum two.

also there is a similar emulator called "86BOX" ported from PCEM or the other way around,I'm not really sure
both have similar features I tried both and Id say they are the same

in both cases you can't use a higher cpu than a 75 mhz or 90 mhz pentium
under DOS ,not even having the faster and expensive INTEL cpu due these emulators are very slow very CPU intensive , it seems were done for accuracy
DOSBOX is faster than these but not much faster

in the last 10 years CPUS have not grown very much in single core performance which is the most important thing for emulators
INTEL and AMD focused adding cores which are useless for most programs or games is a marketing issue

ie I have a core i5 8600 which is one of fastest cpus in single core performance today, however it's not twice as fast as a CORE 2 duo 8500, which is 10 years old
to get an idea what I'm talking about , try "CPU-Z" and check single core performance of your cpu and compare with new and old cpus, also you can try Cinebench or check scores on the web etc

so my main config is a Pentium 75 because all faster CPUS don't works fine
can anyone confirm this??

Even Pentium 75 is overkill for DOS 6.22. I remember using MOSLOW even on P90.

You have percent measure on top of pcem screen - it shows at what speed you are running, and it top speed will be limited by how much juice you have in your computer.

I have 2 i7 computers 2nd and 8th generation processor, both with 32GB memory.

First one is 4 core, 8 threads, 2.2GHz, max turbo boost 3.1, but top speed I can emulate with emulation being 100% was Pentium 90.

New i7 can run Pentium 233 with 100%.

Send me 1 of those, so I don't have to emulate MAC OS 7.5 and 8.1....

Actually, never mind, I would still emulate them.

Just for your info, I have nothing against Macs and specially nothing against Amigas.

I don't think so, they have'nt enough single core performance

I am at work, so can't make you picture, but here is retroplay playing Sega Rally2 on P233 with MMX @ 100%:

Mrz · 16 November 2018, 13:24

sega rally 2 is a windows game
virtual pc can play this game perfectly even in a old pentium 4

emulating windows is not the same thing than DOS, which requires much more cpu power

Anubis · 16 November 2018, 13:33

You got that wrong somehow. Reason retroplay mentioned this works well for him, it is because it is first emulator that he can use his wireless pads to play without issues.

Back to your issue, if he reboots to MSDOS, it will play any DOS game @ the same speed. For example, even on P90 Wing COmmander is too fast, some games I played on this and got good results - Warcraft, Warcraft 2 (both DOS versions), and did not have any issues.

Just make sure you have DOS part installed correctly with correct settings and drivers (if you are using DOS6.22 or Win95)

For Win98, I always suggested creation of DOS shortcuts with different configurations. For example one with CD ROM and EMS, other one without CD ROM and EMS, 3rd one without EMS. It is easy to do it in Win98 and you can even go step closer and use DOS choice to create menu in single shortcut that will prompt what specs to run.

Let us know if you need help with any of it.

BTW, what game are you trying to play?

ps. Here is my old topic on Win98 shortcuts, how to create them and set them up:

nope
there is no cpu in the market which can run DOS games at pentium 233 speed under emulation

no game in particular
I was testing PCEM just for DOS games
for windows games there are better options like VIrtual PC, VMware etc

also for sega rally 2 you can play it direct on win 7 or win 10 using Nglide or DGVoodoo

Depends on the model.
My trusty Haswell i7-4790K has no problems staying on a solid 100% all the time (ranked 15 on the list below).

Right (see attached images)

Image made with game running in DOS 6.22.

While both VMWare and and Virtual PC have their purpose (I use VMWare on daily bases), neither are meant for gaming. DirectX in Win98 is not supported for either one. VMWare supports little bit of it ONLY for WinXP client. Processor is not emulated in either one.

PCem main purpose is gaming, it supports retro hardware and it excels where both of those fail.

He he, you show em Anubis

Try with Duke3D too I would say, Prince of Persia runs even on an Apple II but Duke3D made my 486 melt.

LOL....

what was that song - look what you made me do...

This is with munt still running, not being utilized by game, as I did not find roland in sound setup.

gimbal · 16 November 2018, 16:02

Great! So If you're really ready to push the envelope then Carmageddon needs to be put to the test

That game melted higher-end Pentiums.

(Disclaimer: at this point I'm just curious what I can make you do).

Anubis · 16 November 2018, 16:13

LOL...

Thanks, but no thanks.

You can show us results from P166 tho.

[ Show youtube player ]

One game that I am planning to run is Privater 2: Darkening

On my good ol' P2 450 game was unplayable fast, while on my good old Packard Bell P200 worked just fine. Can't remembering it running it on P233 (had 2 of those until few years back)

Another game I never completed.

Mrz · 29 December 2018, 10:08

btw,

I was testing VMware workstation emulating DOS 6.22
is very fast compared to PCEM which is slow , emulates a pentium 75mhz

in my computer according to a DOS bench tool called topbench, is has the speed of a Pentium III 1 ghz

The problem is that VMware DOS emulation is not very complete, it have soundblaster emulation but not MIDI emulation, so those games which use midi for music ie goblins 2, monkey island, doom etc , the music will not work

anyways I was surprised by the speed of this, I tried Fusion DOS which emulates a MAC, this DOS emulator need a fast CPU worked fine and fast here
also I tried DOSUAE which needs a fast CPU but not worked, it crash

lesta_smsc · 29 December 2018, 10:27

I was under impression that the processor power of PCEmu was enough for most DOS games?

I've used VM for DOS. I wasn't aware of MIDI issue as it can run MIDI within Windows interface. Maybe it needs Soundblaster drivers configuring?

I recall my old PC having a specific autoexec.bat that it ran when it went into DOS mode that would configure soundcard for DOS. Maybe something similar would help?

yes midi works in vmware if you install any version of windows, I have installed winxp for testing purposes and I confirm it works
but midi in DOS not works, or at least I could not make it work

here is link I just found, it says you can get you can either have AdLib/OPL3 emulation, OR the PCM/Wave.
but you can’t do both at the same time.

VirtualBox does Soundblaster emulation. I've not tried it for DOS yet but seems like it might work.

virtual box is a turtle I don't think will be faster than PCEM
anyways if you already have installed in your computer install DOS and report here if worked fine etc thanks

What? The performance in VirtualBox is almost as good as running the OS natively.

Virtualisation is much different (and much more efficient) than emulation.
