ROG Strix G614JI Screen / Lag Issue with GPU?

[Ciprus0]

 I have included a picture with the issue I am describing. This lag/screen issue happens all the time. When my computer isn't plugged in, it will have this issue more often AND eventually blue screen with the reason "Video Memory Management Internal". 

When playing Subnautica the screen "lags" every 5 seconds usually, which is not the same issue in the screenshot. Would assume this is a GPU issue. I also have Ghelper and it sometimes helps but the issue still occurs.

Worth noting that in Armoury Crate the GPU would shift between 0% and a higher % power, same time that the screen lagged.   

Any help?

Hello,

The laptop when on battery mode is usually using the intel GPU as the primary display adapter, gaming it's suppose to switch to the nvidia.

So maybe you have 2 issues or just one but you can try something to run on the nvidia only even in battery mode, enter the bios and set the primary display output to dGPU only and see what happens.

Whilst you do that how is the laptop thermal performance, temperatures and stuff?

Hardware monitor will show more and log the temperatures as min, max so you can see how hot it gets when playing a game, if it's overheating you will get lag / stutters pretty much all the time.
