Hi people!Today i had a problem with my radeon video cards.I tried switching to Radeon 520 for gaming,but still it uses the R5 int. graphics.I tried all the methods on the internet!(Checking Graphics settings on windows and set to High performance each game,but power saving and high performance have both the integrated graphics(Radeon R5 Graphics.The other option i tried is to unistall the new driver and switch to an old version like the 1.9 driver that had switchable drivers.That didn't worked too because it didn't showed me that option,but i did some changes in the additional amd overdrive options.There showed me the ,,Switching graphics options,,.The last option was to change settings from power options,that didn't worked too, i setup all to ,,Maximize Performance,,).I mention that my radeon 520 is detected by the control panel of the driver,and by device manager too!
Here are my specs:

Sorry for bad english,i wrote this thread very fast!
I would clean install the latest driver for your APU using DDU in safe mode.
Here is the latest driver for your laptop https://www.amd.com/en/support/apu/amd-series-processors/amd-a9-series-apu-for-laptops/7th-gen-a9-94...
I tried your method,still the same thing.I booted into safe mode,unistalled the drivers with DDU,booted up into windows and installed the drivers.
This Acer Thread on your laptop model explains how the Integrated and Discrete GPU works together from Acer employee: https://community.acer.com/en/discussion/546431/aspire-3-a315-21g-2gb-dedicated-vram-underutilized
Also check to make sure your Laptop has the latest BIOS/UEFI and CHIPSET versions installed. Plus your laptop Windows MUST be fully updated via Windows Update for AMD Drivers to work correctly: https://www.acer.com/ac/en/ID/content/support-product/7304?b=1

Hi!I tried your methods.I didn't installed the old vga driver.I reinstalled the windows(1909 version and wiped all the disks) on uefi boot,updated the bios and installed the newest radeon drivers(the recommended ones),and made all the settings from power options.But here's the same problem:
It shows the same GPU.
And here's how windows is using the discrete GPU:
Start playing a game and while the game is running see if the Discrete GPU is being used.
As it was mentioned by the Acer Employee, the Discrete GPU is used ONLY when it is needed like during a game.
Also make sure you have Radeon Settings are configured correctly to run switchable graphics in your laptop: https://www.amd.com/en/support/kb/faq/dh-017#SGApplication
The laptop's Discrete GPU 520, as far as I am aware, the vRAM is fixed. The only vRAM you can increase is the Integrated Graphics. Normally 2 gbytes of vRAM is the maximum RAM you can assign to your R5 Integrated GPU via BIOS Settings.
Hey,thanks for your reply.I ran minecraft on the radeon 520 gpu and it shows in debugging mode.The problem is it uses the same memory as the R5(80 Megabyes).Are they the same gpu?And yes!How can i access those settings through bios?Are they hidden features?
From what I have read about Minecraft (JAVA base game) is that it is a CPU dependent game. It uses mainly the CPU to run the game rather than the GPU.
Which might explain why the 520 is not being used.
Found this old but more recent thread that explains how you can enable your laptop GPU to use Minecraft instead of the CPU: Minecraft is not using my AMD Graphics card instead using my Integrated graphics card
The Radeon 520 is a separate GPU in your laptop with either 1 or 2 gbytes of RAM memory. The R5 is the Integrated GPU that is built into and is part of your processor.
The R5 uses your Laptop SYSTEM RAM MEMORY as it vRAM. That is why, at least on Desktop PC, you can change the amount of RAM MEMORY your R5 can use from your PC SYSTEM RAM MEMORY.
It is possible on some Laptops you can't change the amount of SYSTEM RAM MEMORY your R5//6/7 uses. You need to ask your Laptop Support about that and how to get into BIOS Settings to change it if possible.
