Installing an executable with limited execution priority

(1/2) > >>

superticker:
I have one game program that sucks CPU time, but it's only this program. It's so bad, that after quitting this program, the time-slice quantums are adjusted by Windows XP to make all the other programs sluggish. The only way I know to reset these quantums is to log out, then log back into Windows again. Is there a resource kit program that can be used to install this one program (executable) at a lower priority?

I also have exactly the same question for the Firefox plugin-container executable that seems to hog CPU cycles when visiting certain web pages with many DoubleClick Flash ads. The Chrome browser doesn't have this problem.

--- ---C:\Program Files\Mozilla Firefox\plugin-container.exe

Other than that, all programs behave well on my Windows XP system, so I would like to avoid solutions that would affect all other well behaved programs.

What? :huh: - is that actually what happens? (there is - or at least used to be - some quantum/timeslice config you could go at in the registry, but afaik that required a reboot, and I'm not sure the settings work any longer... and if a game messed with them, it would seem weird that logging off/on would restore if quitting the game didn't).

Differently privileged stuff on XP (and everything before it) was a headache, Vistas UAC is actually quite a godsend in that regard. You could probably create a non-privileged user and use "run as user", but it's been years since I messed with it (thankfully!) so the details are hazy. Other methods to drop privileges are flaky.

But are you sure it's a high vs. low privilege thing? Could it be something else, like the CPU/GPU overheating and causing thermal throttling - and that "logging out fixes it" is because of the time it takes doing the relog jig, rather than the act of relogging?

As for flash, it's a well-known hog, and I doubt there's much you can do about it in Firefox (apart from uninstalling :D) - Chrome doesn't use the default Adobe plugin, they have their own tweaked version. If Process Tamer on plugin-container doesn't help, I dunno - my experience is that flash is generally a pretty sluggish hog.

Well, what else can it be? Sometimes (75% of the time) I can run the game and exit without any problems. Other times, if I enter, then exit the game for 5 seconds, things are sluggish afterwards. Logging out and back in always fixes it immediately.

It might be the game latches on to a Windows resource and fails to release it upon exiting. Logging out simply releases that resource. I've tried debugging it with process explorer without success. What other monitoring utility would you recommend that shows system resource allocations?

I've never used Process Tamer. I was hoping to setup some special priorities on these problem executables so I wouldn't need Process Tamer in the first place.

That is a very good question :) - I just wouldn't expect anything as "near kernel level" as thread scheduling to be fixed by a mere relog.

Process explorer would be my best bet to start with. There's nothing fishy to spot? Is CPU and memory usage (both the overall as well as looking at individual processes) at normal levels, or is anything spiking? Can you describe the effects of the sluggishness?

Ah, I thought you had already tried PT since you posted in this forum :)

Anyway, would you care to name the game? Perhaps somebody else could take a look at it and try to reproduce, or perhaps there's known quirkiness or something.

Shades:
A quick search through the "tubes" made me find:
- open the command prompt
- type (for example): start /low notepad.exe

Put the above in a batch file, associate the desired icon with it and done.
There is one problem with this way of starting an application. The use of quotes is not allowed...So if the executable is stored in a folder with spaces in its name, you will have a problem. Solvable by putting the folder into the PATH variable, I would think.

Or did I understand the request incorrectly?
