From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What were some of the positives and negatives? Me personally, I have an RDNA2 card and got bitten by the gamma being too dark on hardware cursors (now resolved) and memory clock stuck at 1 GHz with some refresh rates (workaround is not to use refresh above ~144 Hz).
I have an RDNA3 card (upgraded from a 1080) and am running a multi-boot triple-head setup with mixed refresh rates (60, 144).
Pros: most things work and work well. Installation of the physical card went without a hitch and it was relatively simple to install the drivers. No issues with web video, streaming, video encoding, or standard use.
Cons: mesa, amdgpu, and Windows drivers are all lacking significant features - I am still unable to reliably control fan curves/speeds, clock speeds, etc. FreeSync is unusable as well. I have also been experiencing regular crashes on certain games (BG3, Apex Legends, etc.) and support has been nonexistent, despite similar complaints from other users. When the card does crash, it usually results in a ring timeout and an accompanied total session crash. AMD does not seem to be responsive to these issues in either their official forum or any other space where people are lodging complaints.
The hardware seems fine; the drivers are the main issue. If I had to do it over again, I'd hold my nose and buy NVIDIA.
EDIT: regarding the cursor issue, I've had to switch to a software cursor on Linux. The hardware cursor wasn't showing up at all.
Regarding game-specific issues, it seems a lot of problems stem from either a greedy low power mode or DirectX issues. I've had to set udev rules to alleviate some of my issues, but it hasn't solved everything.
EDIT 2: For anyone who comes across this post, it seems like the vast majority of the crashes on linux have been resolved as of kernel 6.7. Still lacking fine-grained control over fans/clocks, but stability seems much improved.
The ring issues are killing me right now on my Radeon 680M. This isn't brought up enough when people talk about using AMD on Linux.
Odd, Freesync should work for you though? What's the issue you're experiencing?
It was inconsistently causing gamma flickering with certain fullscreen applications. I haven't seen it since disabling it on my monitor.
Are you using wayland by any chance? Freesync was also causing flickering when i was trying out wayland recently, so i guess i'll be staying on xorg lol.
Nope, X and i3 here.
Ah, that's unfortunate, was worth a shot.
