GPU performance while unplugged

[huey_placard]

My GPU performance drops dramatically (by approximately 75%) while on battery.  While benchmarking using Unigine Superpostion at 1080 High setting, while charging I get an average of 57 FPS, and while on battery I get an average of 14 FPS.  Before doing this test, in the Nvidia control panel I set the Power Management Mode to "Prefer Maximum Performance", and the results aren't very different from "Optimal Power" mode.

I found the following link with suggestions for a different model, but the issue seems very similar. Are these the best suggestions here as well?   Should I first just check for later Nvidia drivers, instead of all the other stuff?

I normally don't care about GPU performance while on battery.  In fact I was upset to learn that my model doesn't support Optimus, because I wanted ability to switch to iGPU while on battery.  But I do expect there will be situations once in a while where I'll need to have good GPU performance while unplugged (at the expense of terrible battery life).

I'm also kind of worried that if I do fix this issue, I won't have a way to throttle back GPU performance while unplugged, for times where I'm more concerend about battery life than GPU performance.  So if I fix this issue, is there a way afterwards to manually dial back the max GPU performance while on battery?

Update:  @Praveen196, thanks for the suggestions below.  I don't want to try the solutions just yet as I've been kind of busy and I want to go through it carefully.   So I'm going to go ahead and mark this as resolved for now.  If when I try it, it doesn't work, then I'll come back.    Thanks again.

@huey_placard Welcome to HP Community!

I understand that you are facing a GPU performance issues while unplugged.

I will need a few details to provide an accurate solution; 

When was the last time it worked without these issues (date)? 

Which games are causing these issues and are they online games or installed on your PC? 

Have you attempted any steps on your own before posting on HP Forums? 

What is the product number of your computer? (Ensure you don't share any personal information such as serial, phone number, email ID, etc..). 

  

In the meantime, you may try the below steps, as even if the game is compatible with your system hardware it may have a slow performance because you are using the windows 8, 8.1 or 10 as the OS uses most of the CPU & graphics card usage, you might want to reduce the visual effects for windows to save the amount of CPU & Graphics card usage required to run your game properly. 

  

Here's how you do it: 

• Go to Start Menu > click on Settings. 

• Type performance > choose to Adjust the appearance and performance of Windows.  

• In the new window, go to the Visual Effects and select Adjust for best performance. 

• Click Apply and ok...this should do the trick.
