I'm using laptop Alienware 17 R2 (early 2015), with optimus NVIDIA GTX 980M and Intel HD 4600. Using the latest driver from both Intel and NVIDIA. I have been tested it for several days, I enabled Hwinfo sensor OSD and use MSI Afterburn to display the sensor info of my NVIDIA GPU when I'm playing games. I saw that in the game, sometimes Hwinfo report everything is 0 with NVIDIA GPU, but MSI Afterburn itself report the GPU working continuously. I play GTA V, so I can say that it use NVIDIA all the time, nothing related to Intel here. But I don't know why Hwinfo report thing differently.
Do you think you can fix it? Or maybe because windows 10, nvidia, intel work independently and cause such thing like this?
The first 4 line is from MSI Afterburn itself. HWinfo report 0 in the line 5 - GPU temp, 6 - Clock. sometimes it report correctly
