When you're working on a project, the time comes to find the minimum hardware requirements for it, for example :
Intel Pentium or AMD K5 processor with 166 MHz 16 MB RAM etc.

Clearly, how to define this using PB with MS API under x_86/x_64 (windows/PB) ?

Thanks.

"normal", you have the same requirement as the used OS

Sorry ts-soft, I explain badly what i mean.
Minimum hardware requirements is not for me but for peoples who want to use/try my app.

Well, you can look at the DLLs which your application uses (DependencyWalker), watch the Windows Versions of the API commands that you or libraries of your program use, ... watch the taskmanager to see how much RAM it uses at extreme points etc..

in general, what is the standard minimum hardware requirement these days?

There is no such thing as a standard minimum hardware requirement, it depends on the software.

is there any simple method for determining the minimum specs a program needs, or is just a case of hand-wavery-a-wizard-did-it*?
*by that I mean just deciding on something that seems "right"

As a base rule, I'd suggest Windows XP 256 MB. I've done some experimenting with Windows XP on low-end machines...

... and that seems to be the bottom line for acceptable performance of XP. Unless you've creating a power starving kind of program you'd be fine I guess.

I don't think there is a hard and fast rule or easy tool, to be honest. When in doubt, install your application on a poorly endowed computer and just try it. Yeah, I know. You never expected to have any more use for that ol' P3 clunker, now did you?

I guess I'll have to find something else to keep the table level

i dont think so that its so imp. 2 know it!

It's easy to work out requirements. Check how hard drive space it uses when running, and how much memory in the Task Manager. That's basically it! What other requirements matter? Speed? Not an issue unless it's a hard-core FPS game; apps can use any processor speed as long the user doesn't mind any delays.

I had an app refuse to install on one of my older PCs due to it being a P4. The funny this is, I would've PAID for it if I could install and run it, because I didn't care how long it takes to process; but the author, in his infinite wisdom, has decreed that PC to be "below" his app. That's fine, you ain't getting my money then, biatch.

Never alienate your customers. Recommend a CPU if you have to, but never deny the user the ability to run it anyway.

Thanks guys for your answers.
