When playing games, I noticed that my iGPU is under load, as well as my dedicated card, when the game is running on the dGPU. It shows in the game that it is using the dGPU, and there is a significant difference in fps when it does show that is is using the dGPU compared to when it isn't, so I know it is not because I have not told the program to use the dGPU. I am wondering why it is using both, and if one is able to make it only use the dGPU and not the iGPU, as I think it is slowing my game down. The only game I have seen this is Minecraft 1.8.9.

I have linked a screenshot that shows my problem http/
