Re: Dynarec execution rate plummeting drastically at DOS pro

Yeah, I get it. Check out this post, though: http://pcem-emulator.co.uk/phpBB3/viewtopic.php?f=3&t=85&start=90#p1077 That's Tom's most recent dynarec performance summary. Note, right off the bat: DOS prompt - 96% faster (55% / 108%) 108% at the DOS prompt! And I believe that Tom was running the fast...

Re: Dynarec execution rate plummeting drastically at DOS pro

ecksemess, could you post your CONFIG.SYS and AUTOEXEC.BAT files here? There may be something there causing slowdown, most of my benchmarking was done on a clean boot. In general though, idling (on pretty much any operating system) hits all the weak points in the current recompiler and hence doesn'...

Dynarec execution rate plummeting drastically at DOS prompt

In general, I've been getting great performance out of the dynarec, but I've noticed that the execution percentage plummets strangely while idling at the DOS prompt, in ways that suggest that something other than the usual issue of an idle loop hitting one of the dynarec's weak points may be the cul...

Patch: Fix for error in re-ordering of ROM set enum

An oversight in the re-ordering of the ROM set enum in r346 has caused problems for the Phoenix 386 and the DTK 386, which have now lost their 386 classification. Actually, the problem was worse than that, as there were several misclassifications even before the re-ordering in r346 (IBM PS/1 Model 2...

Re: Cache size?

Granted that the cache simulation feature obviously has its shortcomings, I've found it incredibly useful as an auxiliary speed- and performance-tweaking feature when the main settings on their own aren't quite allowing me to get the emulated system to behave the way I want it to. I've spoken to sev...

Re: r328: OS/2 Warp 3 format error; CD access crashes PCem

Return to Zork required 19,519 *KB* of RAM for its sound drivers?! No wonder I had so much trouble getting that game running! ;) In all seriousness, yes, 580-some KB was an incredibly daunting requirement back in the day. I remember. Oh god, do I remember.

Re: r328: OS/2 Warp 3 format error; CD access crashes PCem

Don't install quemm. or emm386 or anything else like it. try to keep the configuration as PLAIN and SIMPLE as possible. More like, the bug in PCem needs to be fixed. Again, I did I=B000-B7FF on real hardware all the time and never had these problems. Only in PCem does that cause problems. PCem's me...

By all means, give it a try--I personally have only had the issues after using fullscreen, but what you describe sounds very much like something that this patch might fix.

Bugfix patch: host mouse pointer behavior after fullscreen

Attached is a patch for win.c which should fix several annoying glitches I've noticed that sometimes cause the host mouse pointer to disappear, freeze, or behave badly after switching into or out of fullscreen mode. The bugs only come up under certain circumstances and on certain host configurations...

I'm sure I speak for many when I say that your "insanity" is one of the better things to come along in the emulation scene in many years, Tom. ;) You've single-handedly brought the current state of PC emulation up to something respectable. It's actually been quite something to observe the progress y...

Re: Dynamic recompiler

I see. For what it's worth, I've greatly enjoyed having the setting there to mess about with, hack or no hack. I'd be sad to see it go, even if its value is more as a semi-novelty than an actual respectable feature. Thanks for the info.

Re: Dynamic recompiler

Understood. Speaking of which, if/when you ever turn your attention toward improving the cache emulation, would it be feasible to make it settable to actual values, instead of simply "a little/some/a lot", etc.? It's a relatively minor thing, but it is somewhat jarring in contrast to the highly accu...

Re: Dynamic recompiler

rflego, now that the bug has been fixed, are you getting a consistent 100% or a consistent 30% when you run the MMX 233 on the Windows desktop? If 100%, can you try a bunch of high-intensity games and applications to see if anything you do ever makes the execution dip below 100%? You do appear to ha...

In theory, you should be able to use a build with SA1988's NE2000 emulation patched in to do exactly what you describe with no major difficulty.

Re: Dynamic recompiler

Wow! You weren't kidding. Your execution speed for sound playback is dropping from about 1.0 to 0.15 MIPS, and recompiled speed correspondingly from 100 to 15 MIPS, just by your opening and closing of the config. I'm nowhere near familiar enough with the recompiler to know how to interpret that, but...

Re: Question about the audio

I totally agree, Tom. Actually, I consider the audio stuttering upon slowdown to be a feature, not a bug. I strongly value accuracy and authenticity, so I like to avoid running below 100% whenever possible. It's very convenient to have an unmistakable cue to alert me to the fact that that's happenin...
