Hello,

Whithout using Task manager or registry modifications

Thanks in advance

test ....

@Emile , why do you want to do this? I’ve never used anything other than a standard shortcut with Admin privileges. Anything more than that is unnecessary.

Hello,

Without using Task manager or registry modifications

There are a couple of ways I use to manage various CPU/GPU priorities.

• Scripting the P3D startup process to start itself with a defined priority.

• Process Lassoo can manage CPU/GPU application priorities, however I use it more to define CPU core usage across multiple programs.

tasklist /nh /fi "imagename eq Prepar3D.exe" | find /i "Prepar3D.exe" > nul ||(START "PREPAR3D" /ABOVENORMAL     /D "H:\Lockheed Martin\Prepar3D v4" /I "E:\FSX Addons\DisplayChanger\dc2.exe" -configure="E:\FSX Addons\DisplayChanger\P3D-DSR-60HZ-2560x1440.xml" "H:\Lockheed Martin\Prepar3D v4\Prepar3D.exe")

Here I start P3D with an "/ABOVENORMAL" priority, the script also automatically changes screen resolutions as defined in the xml file of "P3D-DSR-60HZ-2560x1440.xml" using a small application named dc2.exe (Display Changer).

My main script also kills various running tasks, clears memory and starts various P3D related programs like landing rate monitor, Little Nav Map, JoyToKey, Active Sky and a few other bits and pieces.

Also you need to be aware programs started by P3D will inherit P3D's priority and too much priority will actually slow things down and can result in stuttering that wouldn't otherwise occur. This is because Windows is not a great platform for true multitasking and is certainly not a realtime O/S.

The below links have info, noting Microsoft will redirect the links to whatever links they are using now, as MS are known for changing for change sake (and usually breaking something in the process).

My idea was to check if changing the game priority has a positive impact on the FPS

And I try to avolid changing the registry ...

Hi Rogen

I use Wise game booster to remove "all" the unneeded...

Thanks for your information but it is to complicated for an old progammer (85)

I doubt you’ll see anything significantly better. If you want to boost your frame rates the most effective way is to buy Lossless Scaling on the Steam platform. For under 10 euros it will double them.

I purchased Lossless Scaling on the official website https://losslessscaling.com/ for 7 bucks. And it does not require mandatory launch of the Steam client. For me, this way is more convenient.

It`s here: Lossless Scaling

If it's all too complex (and your CPU isn't already pegged when P3D isn't running) then just leave it alone. You will NOT get any frame rate improvement, and are far more likely to degrde something else.
