AMD Switchable Graphics not Utilizing my R9 M385X (Lenovo Y700-15ACZ)

Games and other applications do not utilize the discrete graphics card on my laptop.

Using Windows Device Manager, Speccy, CPU-Z, or GPU-Z, both my R6 Graphics and my R9M385X Graphics are visible.

Laptop Power Plan is set to High Performance, have tried setting graphics profile in Radeon Settings to both Optimize Performance and Optimize Graphics Quality and received no change.

Applications in Radeon Settings have been manually set to run in High Performance mode (as opposed to Power Saving or Based on Power Source) to no avail.

UEFI Graphics settings are set to Discrete.

Despite this, when using CPU-Z, GPU-Z, or Windows Resource Monitor to monitor system load, the R9 does not receive any system load whatsoever. Only when running a Render TEst with GPU-Z can I see any system load being placed on the R9. Additionally, Games that give me the ability to choose my display adapter present the AMD Radeon R6 Graphics as the only option.

I have tried uninstalling ALL AMD Drivers, Performing a clean uninstall by using the DDU tool, and installing the newest compatible AMD drivers, this has not changed.

Every 3 or 4 weeks, I will receive a warning notification in Radeon Settings that my Crossfire bridge is not properly connected, but until recently though nothing of this (because as far as I knew, my iGPU and dGPU do not utilize a crossfire bridge in order to work, and my system still detected both Display Adapters). It should be noted that the warning is not consistent upon every boot of the device, and appears randomly.

DxDiag and Speccy Summary are attached, and I will be more than happy to attach any other required documentation.

Try following these instructions from AMD Forum on how to install AMD drivers and how to configure your switchable graphics on your laptop:

Laptop graphics update...How to​ and How to Configure Laptop Switchable Graphics .

It is best to download and install the AMD drivers from Lenovo for your laptop. Also make sure you have the latest BIOS and Chipset for your Laptop installed from Lenovo Support.

You need to download the APU driver from AMD Support. This is the generic driver for your Laptop : APU

Found this at Lenovo Support for Laptop Y700-15acz :laptops and netbooks :: ideapad y series laptops :: y700 15acz :: 80ny Lenovo PC Support

It has a newer BIOS than the one you have installed IF THIS IS THE CORRECT LAPTOP MODEL AND MAKE!

Re: AMD Switchable Graphics not Utilizing my R9 M385X (Lenovo Y700-15ACZ)

The article https://community.amd.com/docs/DOC-1581 is good. The only problem - my 'Radeon settings' has version 20108.0216.1847.33779 and doesn't have neither 'additional settings' now 'switchable application settings'! So the question appeared again - how to switch between Intel and AMD graphics?!  I have Windows 10 Pro, AMD HD 8790M, Dell E8540.

Why?! Why AMD always change GUI?! it was before Catalyst Control Center then Radeon Settings, Please be consistent!

Both settings (Switchable Application Setting and Switchable Application

Monitor) are in the most recent compatible Radeon Settings.

I tried the fresh install of the Drivers provided by Lenovo, then installed

the Generic APU driver from AMD on top of that but have seen no changes in

my performance.

Games that I surpass the Recommended specifications for with my Discrete

GPU are stuttery and sometimes unplayable at anything other than the lowest

settings.

Hope this helps you .

There's no words that can describe this relief when I found your post.

I've been struggling with this piece of S!#@ laptop for almost 3 years trying to find a way to make it work so that my 1000 euros wouldn't be wasted. Tbh if I would've done more overtime at work instead of trying to make use of this bad product I would be on top. This project has affected my relationship and my mental health.

I'm forever grateful for your service and wish you the best since you've proven yourself to be an outstanding individual and worthy person to overcome any obstacle you'll ever face.
