Re: A design suggestion for PCEM

I like to see disk activity all the time. That is why the engineers who designed the computers put the hd led. Any virtualizer offers this. Fair enough. :) I don't have enough experience with emulators to say how many, as a percentage, offer that option. But I'm willing to accept an assertion that ...

Re: PCem v17 running slow/lagging

I don't know what options are available for Ryzen machines, but on my Xeon machine, turning off hyper threading and disabling the clock down feature (so the cpu is running at full clock constantly) improved performance noticeably. Interesting. What CPU(s) could you run with hyper-threading and cloc...

Re: A design suggestion for PCEM

I find it very uncomfortable to have to keep bringing the machine window forward all the time to see disk activity. Why do you need to see disk activity? If it is spending 10+ seconds to display the contents of a drive, that may be cause for a bug report. Otherwise, I find it strange that disk acti...

Re: dos program like prime95 to stress emulated CPU ?

Which indicates that the problems reported with Daggerfall in this post:

are due to a PII/233MHz CPU being too fast for Daggerfall.

One ongoing thing I've noticed in PCEM is issues with the mouse movement feeling weird like the acceleration or scaling isn't quite right. At least in Windows 98SE.

Is there a fix or setting for that I'm missing?
Did mouse acceleration exist in Win98? you might want to turn it on/off.

Turning off 'internal cache' is a proxy for disabling the dynamic recompiler. PCem doesn't have any cache emulation.
That does leave me confused over where the speedup is coming from, then.

Re: PCem v17 running slow/lagging

Turning off cache doesn't make performance miracles. Here's a P2 233 caches.jpg So so far, based on information around the forum, turning off the CPU's internal cache has sped up Daggerfall and Civ 2, but slowed down Quake 3. Neither Daggerfall nor Civ 2 use the Voodoo/3D graphics card (Daggerfall ...

Re: Request - Rendition Verite V1000

Why would you want Verite support in PCem only to emulate Rendition APIs? IMHO, a PCem with Verite support would emulate a real PC with that card, on which the APIs would run natively, provided you install the drivers :) If you really want to emulate the APIs, then current PCem should do, but you w...

Recompiler cache constantly creating and removing blocks when running games

So far I've only tested this in Civilization II and Interstate '76, but the results are consistent with both: Whether sitting in a menu or playing the game, recompiler blocks are constantly being created, removed, and sometimes evicted. I'm not an expert on caches; however, this seems strange to me....

You can see how much CPU time the Voodoo threads are taking in the PCem status window.

Re: Pentium MMX 200 emulation problem

Ok, so your graphics card is basically irrelevant here - PCem doesn't use it. OTOH, your CPU is very old. Even at 5-7% uplift IPC for a single core per generation, an equivalent Intel 9X00k CPU beats it by +34-50%. The 9X00k will probably also run at around *4.5-5.0 GHz (so +28-31%), and use modern ...
