WARNING! WARNING!
Many of these utilities could break your system. It's going to take some searching that can find anything that works in Windows 2000 / XP. I doubt anything could do it.

But if you want to test them, test them. Wink

List of Slowdown Utlities
-------------------------------

AT-SLOW - AT-SLOW is an alternate slowdown utility that works well on 286, 386, and 486-class machines, utilizing the Real-Time Clock chip found in 286's and above.
http://www.oldskool.org/pc/help/oldonne...slo410.zip

Bremze - Bremze (Latvian for 'brake') slows down PC performance by controlling the speed of execution of programs. This feature can be useful when running old processor-dependent programs on new PCs, particularly to decrease the speed of games for 'better results', or when wishing to gain a better understanding of the sequences and functioning of programs, etc. Big diapason of braking coefficients (enough to fastest PCs), braking level control and switch on/off by hot-keys, control output trough PC speeker and screen corner. Full command line control. Slows down DOS and Windows programs. Versions for both interrupts are available - 08h and 70h.
http://ansis.folklora.lv/bremze/

CPUKiller - CPUKILLER takes the control of your processor and makes the resource occupancy grow enough to slow down the execution of other applications . When you want your computer to return at the normal speed you have only to stop CPUKILLER!.
You can even configure CPUKILLER to launch automatically your old programs and to terminate itself when they exits!
http://www.cpukiller.com/

ICD/ICE - ICD and ICE disable and enable a 486 or Pentium's internal cache, which can result in a smooth slowdown.
http://www.oldskool.org/pc/help/oldonne...icdice.zip

MIPS - MIPS is the speed benchmark Trixter uses when he is trying to get his PC down to a certain speed (and if he uses it, you know it's got the oldskool seal of approval Wink. It has "1.0" ratings for a 4.77MHz 8088, 8MHz AT, and 16 MHz 386, so you can gauge how close you are to a certain speed. For example: If you were aiming for an 8MHz 286 and your "number" according to MIPS was 1.7, you'd know that you were too fast and had to slow down your PC a bit more. Conversely, if your "number" after running MIPS was 0.6, you'd know that you slowed down your PC too much and should try again. Just run it and you'll see what he means. Note: This utility reports absolutely wacko results on anything over a 486/66's speed, so if you get numbers that don't make sense, you'll know that your machine is over a 486/66's speed and you need to slow it down further.
http://www.oldskool.org/pc/help/oldonne...s/mips.zip

MoSlo - Mo'Slo is used to slow a specific application or batch file.
http://www.hpaa.com/moslo/

MySLOW - MySLOW is a public domain utility for slowing down MS-DOS games and applications run under Windows 95, Windows 98 and Windows ME.
http://www.csclub.uwaterloo.ca/~rridge/myslow/

PentSlow - It disables branch prediction and the v-pipeline, maybe even the internal cache. There is one drawback: To speed up the system again you have to reset the machine. Still, any hardware slowdowns are more preferable to software, so it's listed above for your perusal.
http://www.oldskool.org/pc/help/oldonne...ntslow.com

Slow486 - Slowdown utility; disables the L1 cache on a 486 and Pentium for a significant and smooth slowdown. Locks up some Pentiums and non-Intel CPUs.
http://???

SlowDOS - SlowDOS is a software based slowdown utility, similar to Mo'slo and Bremze that allows you to customize the amount of slowdown in 0.10ms increments. A combination of throttle and SlowDOS should allow you to put any machine down to the good ole 4.77MHz days.
http://www.waste.org/~winkles/throttle/

SLOWDOWN - SLOWDOWN slows down a fast computer so you can run older programs, or as a troubleshooting aid.
http://members.aol.com/bretjohn/

Throttle - Throttle is a program that, provided your computer meets certain requirements, can slow the CPU speed down in variable steps.
http://www.waste.org/~winkles/throttle/

Turbo - Turbo is a free Windows slowdown utility that lets you slow down your CPU in resource chunks/percentages. It's free, and works pretty well, but lacks many of the advanced features found in shareware Windows slowdown products, like CPUKiller.
http://www.oldskool.org/pc/help/oldonne.../turbo.zip

I recently purchased Mo'Slo 4BIZ, and have tested it under Windows XP and VirtualPC 4.3 with DOS and WFW 3.11. Mo'Slo 4BIZ has two slowdown methods - the second one is supposed to be better for some video applications, but only works on Win 9x / Me. The second method, however, does work with DOS on Virtual PC, even with XP as the host. Also, 4BIZ lets you not only select the percent speed you want - it let's you select the exact speed you want (ie. a var set to 6400 = 166mhz), but that feature doesn't seem to work 100%. I haven't done all the testing, though, that I would like to on it...
Also, it should be noted that the free version of Mo'Slo - Mo'Slo 1.32 only works on computers slower than 700mhz. Mo'Slo Deluxe 2.1 (i've seen it on a few abandonware sites) only works on computers 550mhz and slower. 4BIZ has been fixed to work on computers 1THz and slower...

Ugh, you purchased it? Guess that means no freebies for us. Wink
Sounds like something that should be considered more thoroughly -- that is, something that should be investigated further.

Just to add: MoSlo 4BIZ isn't free, but it does work well. I've had very fast feedback from the author, too, when I was trying to get WipeoutXL properly slowed down, as well as a free upgrade to the latest registered version.

Bremze works really well, but also isn't free (stops working after 5mins). Has anyone registered this program? Is the address still valid.

Neither program works as well under Win2K as they do under 98SE, however.

Shouldn't this be in in Deep Thought? Confused

Any Thoughts? Wink

No! It is (supposed to be) receiving comments. Deep Thought is for (semi-)STATIC CONTENT, not for stuff that is supposed to receive changes/updates/etc.

I need a slow down program that slows down a specific Windows application. Anyone know of one?

Just one? No. Slowdown programs just eat up clock cycles in order to slow down stuff, which means the entire system will be slowed down.

If it helps anyone, I just spent a minute researching SlowDOS, and it looks like it's a bad option if you're running WinNT/2K/XP because it requires the use of GIVEIO.SYS, which I've heard is bad mojo if you're using VDMSound.

It might be nice if we could come up with info on what slowdown methods each utility uses (e.g. software, hardware...) and under which OSes they work (e.g. some don't like NT, or require weird drivers, and some are Windows-based rather than DOS-based). Just a thought.

[EDIT]Whoops! That's Throtte, not SlowDOS... SlowDOS is a software slowdown utility that compliments Throttle's hardware-based slowdown features.

My 2 cents...

Use a secondary (old/slow) PC or PC emulation that will actually run the program at a slower speed (DosBox or sometimes...Bochs). Every experience I've had with "slowdown" utilities has been unpleasant.

The thing is, DosBox chokes BAD on even the 286-level games that I try to run on it (Hyperspeed, Wizardry 7) with my PIII-550, so I have a strong aversion to using it. In addition, a lot of games that I have needed to use slowdown utilities with require 32-bit protected mode (e.g. Daggerfall). Just my 2 cents Wink

Try any of the mid-year SCI games (Police Quest 1 VGA, 3; Space Quest 1 VGA, 4, 5). I played PQ3 through beginning to end on a Celeron 450MHz with DOSBox.

But I got SQ4 working just fine with WinXP+VDMS, with MIDI and everything (of course it uses MT-32 so it sounds a little off). I think I may have needed to use speedset or something though.

But DosBox doesn't yet support MIDI right? So I don't see the point unless there's no way to make it work under VDMS.

MIDI support implemented in DosBox v0.58 Happy
