How can I use .bat files to run games with different power plans?

Hello,

I have created two .cmd files where I can change power plans really quick.
The code in the .cmd files looks like this:

powercfg /s 381b4222-f694-41f0-9685-ff5bb260df2e
exit

This works fine. But now I want to have a .bat file, which activates a power plan until the game is closed.

For example:

I want to change the power plan to high performance. Then a game out of origin or steam should start. When I close the game, power plan should switch back to balanced.

I tried following code, but this still does not work:

start /b "c:\users"username"\desktop" performance.cmd
start /d "d:\games\origin" originclientservice.exe
start /d "d:\games\origin" originwebservice.exe
start /d "d:games\origin\origin games\mass effect andromeda" masseffectandromeda.exe
start /b "c:\users"username"\desktop" balanced.cmd

The game starts, but the balanced power plan is still active. How can I say, that the .bat file has to wait until the game is closed?

Usually putting Pause on the line after a command keeps the .bat file open but the usher has to hit Enter for the file to complete. Don't have a solution for the game program to control that.

I changed code to this and this works but is not optimal:

start /b "c:\users"username"\desktop" performance.cmd
start /d "d:\games\origin\origin games\mass effect andromeda" masseffectandromeda.exe
start /wait "" "c:\users"username"\desktop" balanced.cmd

But now desktop directory opens and I have to activate balanced.cmd manually after closing the game.

Do you find it makes a difference? Certainly for me games don't run any better using high performance compared to balanced.

You can't really do this easily (except for clicking on something manually) as the OS doesn't have a trigger for ending a process AFAIK.

You could write a program to see if d:\games\origin\origin games\mass effect andromeda was running or not and switch power plan.

Something like this - powershell - How to Correctly Check if a Process is running and Stop it - Stack Overflow but add a pause every 5 seconds or something.

There would be a minor (probably negligible) impact and may not actually be worth it. You could do it though.

Technically of course you could put a rocking horse on a Porsche but unless you have a reason to do so it may be pointless.

I don't find Power Plans make any difference personally as Balanced will take whatever resources it needs anyway.
