Is there any way to get my AMD hybrid to work right?

asked 2019-04-19 09:38:20 -0500

So before i explain, this is not fault of fedora, like not at all and the fact i am on F30, the beta is also irrelevant to the issue.

So this issue was affecting my laptop from pretty much first time i installed linux on it, did loads of research about my dedicated GPU running REALLY poorly, no matter what i do if i launch something on it it will run really poor, when it comes to games they usually report high fps as they should run but they are actually outputting low fps.

For example minecraft, i get nice fps on integrated GPU, but on dedicated it will show that its running on 100+ all the time but when i look it it, in reality its like 15-20fps,

I also tried to use it as card passed into VM, unfortunately this is kind of hybrid that realies on integrated GPU, the dedicated cannot work alone, has no outputs. And this is propably all there is to it.

The specs are: Thinkpad E580 CPU I5-8250u iGPU Intel UHD graphics 620 dGPU AMD RX 550 2Gb model

It seems very unlikely that an application would report inflated frames/second for the simple reason: what's the motivation for doing so? Any slowness would naturally be blamed on hardware.

How are you determining the actual frame rate? High speed video analysis? What kind of monitor is in use?

When used in a virtual machine, are you enabling the VM's 2D and 3D acceleration options? What about the AMD-V virtualization support? And PAE/NX exposure to the VM?

Have you done any BIOS updates?

Are you using PRIME? Here's how to configure (if it doesn't work out of the box) and use it:

Install radeontop and run it as admin/root to check dGPU utilisation.

inxi -SMGsxxxz output will show us some useful details.

Sorry for being late

Prime is also placing stuff on dedicated GPU, its just that pretty much everything runs horrible on it

radeontop shows everything on 100% all the time and says Failed to open DRM node, no VRAM support.

I havent done any bios updates, from start i had to downgrade bios to lower version since the newer one has glitch or stupid feature where dGPU will be underclocked pretty much all the time

inxi says ist too big for character limit

Also response to wallyk, i tried about every option for VM it is impossible as i later found it since if i pass it inside, due to muxless setup, its not able to system to use the dGPU since it relies solely on iGPU. i determine framerate by looking at it, difference between 20 30 40 60 is quite big to me i use buitl in monitor and i know its not hardware since it runs perfectly on windows. Also another thing i managed to run warframe qiute decently but thats about only place where i had succes
