associating data types with high priority

[Ric]

Hi,

I have a few programs I like to run in high cpu priority. I can launch them
in this state using "start /high filename". However, I also want them to
start in this space when they are launched by double clicking on a data file
associated with the program. I've tried editing the "open" event in
folder/filetypes options, changing it from "filename %1" to "start /high
filename %1". While this still launches the correct program, it doesn't
start in high priority mode.

Is there a way to do this?

Thanks

Process priorities aren't something you normally want to change. It won't
improve the performance of most applications, since most applications spend
their time waiting for you to do something, and then when there is work to
do, the time is available. Process priority is more meant for things like
sound and video which are trying to give uninterrupted playback, and they
set themselved automatically. You may find that by making these changes,
other programs will stop working correctly.

I set high priority for video capture and my video player (Cyberlink
PowerDVD). In the former case there's no file association so starting with
high priority is easy. In the latter case I often play video by double
clicking on the video file, which launches the player in normal priority. I
couldn't find any options in the player to choose high priority so I have to
do so manually.

Running in normal priority, these applications sometimes stutter or pause
while other programs are very active or doing a lot of disk manipulation.
Setting the priority to high allows them to function smoothly even with a
high cpu load in the background. Since most of the time these applications
are only using 30% or less of the CPU, setting their priority to high has
virtually no impact on the OS or other running processes.
