Hi there,

I'm having an issue with the dedicated GPU.
Laptop model: MSI GT70 2OC.
Integrated GPU: Intel HD 4600
Dedicated GPU: nVIDIA GTX 770m

I've tried the following things:

I've set the global GPU to high performance nVIDIA GPU.
I've reinstalled the nVIDIA Driver.
I've set the power setting to high performance.
I've tried doing this from this thread:

Quote:

This happens when these services are stopped :
1. NVIDIA Driver Helper Service
2. NVIDIA Update Service Daemon.

Start Task Manager .Click the tab "Services" .Click on a button named "Services ..." .Find them.their names .Right click on them .then Properties . Then Click on "Start " and then select Start-up time :
for the first ->Automatic
for the second -service > Automatic(Delayed Start)


Unfortunately, I couldn't find those two services in the registry, and couldn't set them.

I guess now, the only thing I can think of is to do a fresh install, which is a huge inconvenience due to university and work...

Any other ideas?

Thanks in advance.

Make sure you have downloaded the correct driver for the 770m, which is this:

And then follow the instruction at the following link under CLEAN driver installation using the driver you already have or downloaded from the link above. Be sure to select the Nvidia option during the DDU uninstall.

I found the solution.

It was in fact the power setting. I had assumed I switched it to high performance. However, I double checked last night and found that it was on power saver, and before that I kept it at balanced.

Performance is as it should be now.

Darkbreeze, I gave you best solution because although your solution didn't help me specifically, I'm sure it will help others in the future :)
