Question Any way to disable iGPUs (and any significant performance gains in the newest iGPU)?

[Gamefreaknet]

Hi. I have currently a Alienware M17 R1 (OLED 2019) with:
i7 8750H (Intel UHD 630)
RTX 2070 MQ
etc...
and I have set all system preferences so it should use my 2070 most of the time for games however it still tries to offload some of the graphical load (in games) to my iGPU (normally resulting with around 20% - 40% usage on my iGPU and around 50% - 70% usage on my 2070). According to HWinfo my 2070 can run at a maximum of 85 degrees but it rarely goes over 65 degrees despite rarely being used fully whilst my PC still offloads some of the work to my iGPU (which obviously has lower graphical capabilities) however is there a way to disable an iGPU so it just uses my 2070?
(My 2070 is fully up to date running on: Nvidia Game Ready Driver 527.56, Released: 12/08/22 (8th December 2022))

Also are there any significant performance gains from the UHD 630 vs UHD 770?

You can disable the iGPU in Device Manger(by right clicking on the iGPU and disabling the device) though that is not advised. Instead, I'd advise on making sure your BIOS for the laptop is up to date. Then use DDU to uninstall your GPU drivers, source the latest driver from Nvidia's support site then manually install the driver in an elevated command i.e, Right click installer>Run as Administrator.

What OS are you working with?

Yes, you should be able to boot into UEFI using the following steps with Windows 11 (maybe even 10). Start - Type "Reset" - click Reset this PC. By advanced startup, click restart now. Follow the prompts until you find restart in UEFI. After selecting it with your keyboard, you should be able to boot directly into the bios settings. In there, for most laptops, you will see an option that says use multi gpu support (or something similar to graphics) and you would have to change it to "discrete graphics" or make sure "integrated" is removed if that's an option. This is how it's laid out on my Lenovo. I will tell you from experience, that this can cause issues with some instances. I personally disabled my intel display driver in device manager before doing this step to help mitigate potential issues but still faced a few after rebooting. Personally, I think it's best to do discrete graphics during a fresh install so your pc never uses iGPU to begin with. In Rust, when I play in 1440p maxed out graphics and DLSS balanced using OBS for screen recording on NVENC, my FPS improves from my estimated average of 55 FPS to 90 FPS so there's a significant difference. I believe the reason for this is because when you sometimes are running a game using physx and gpu output to a second monitor and your laptop monitor is iGPU, your computer is doing more work than necessary to write to 2 different GPUs than just dedicating to a single GPU, but this is just my hypothesis.
