Help in understanding performance issiues in AMD GPU drivers

[ryba_classic]

Hi,
I'm using an AMD RX 480. Everytime I try to play a game or even just scroll a webpage - the display is laggy stuttering with terrible tearing. I've tried switching from x-server to wayland but that did not help much, AMDGPU or AMDGPU-PRO - still same issiues. To anyone who uses AMD cards how do You overcome this ?

Here are some questions to start off:

Which DE are you using?

Which kernels have you tried?

Do you have sufficient power for your system?

Is your system sufficiently cooled?

Does it work within a live environment?

Does it work with another distro's live environment, e.g. Ubuntu 18.04?

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

1. Stable
2. 4.14 - 4.16
3. Yes - with GPU passtrough everything works fine but in a VM
4. Yes - It never goes beyond 70*C
5. It would be tricky (at least for me) to test games in live but web browsers seemed to work ok
6. I tried on arch from ground up when the leatest kernel was 4.10 - never tried on ubuntu (even if it would be the case - I want to stay on arch based distro).
7. Thank You, I'll keep that in mind

Or maybe I'm missing the bigger picture - the system behaves like as if I had an mechanical hard drive. The effects are very simillar to compare - the whole system pauses for 1-2 sec and then shutters like it's reading something from an old and slow hard drive. When I paly a game for 30-40 min and revisit the same places - the is no stutter - only tearing.
Maybe the issiue lies elseware ?

Also - is there an option for adaptive/dynamic Vsync ? turning on regular Vsync creates an input lag.
