Trend Micro Uncovers Yet Another X.Org Server Vulnerability: CVE-2023-1393

Where you evidence you don't have any.

If you want to claim AMD can do better than the evidence I already presented shows, you are the one who needs to present the evidence of it doing better, e.g. a benchmark of a popular application people use of it doing better.
Try GTA V, it doesn't get more popular than that.

something recent, like from a couple of days ago

I did not say AMD could not do better. GTA-V fails for a completely different reason. Basically here is you cherry picking the failures again.

Issues of games not firing up on different GPUs is not even a Linux or AMD exclusive thing. Just because you have a Nvidia GPU does not mean GTA-V will always work there longest time frame GTA-V refused to fire up on Nvidia was a half a year that was a while back.

Yes wallpaper engine being number 7 at the moment but it daily its 4 after GTA V does start you wondering how much people do play games. Yes in a game focused store you see non gaming things come to the top. The non gaming use case is kind of important. The area Wayland developers talked about increased performance is the non gaming area.

Yes I would say the open source drivers are broken for GTA V with AMD and Intel at the moment. Failure caused by AMD and Intel direct to hardware opengl drivers having particular optional features disabled. Would be interesting to run GTA V with Zink.

Yes the opengl standard says particular things are allowed to be optional as well and by standard you are meant to include code to work around optional parts being missing.

Some of the reason why Valve funds zink development is they will need zink to run older opengl games on Nvidia cards for the same reason GTA V does not work with Mesa AMD and Intel drivers at the moment missing optional opengl extensions.

Nvidia and AMD both have issues of games not working for optional opengl extensions being missing. Yes that on Windows and Linux. AMD has more highly popular games in the top 25. but Nvidia has a quite a few in the top 100 games that don't work as well by the top 300 number of failures have leveled out between AMD and Nvidia caused by missing optional extensions.

So GTA V is you just attempting to win by cherry picking again.

X-plane is 1 particular problem.
Dirt Rally is a different particular problem most likely caused by being close to Opengl specification and having work around for missing extensions and so on and the work around stuff being buggy.
GTA V is simple failure to run if optional extension does not exist problem that generic between AMD and Nvidia and closed and open source drivers.

There is nothing here that says AMD or open source drivers are particularly bad just someone cherry picking attempting to say that.

Nvidia case with Wayland Nvidia says that the DMABUF support is buggy and since Wayland compositors depends on that you expect crap performance with Nvidia until it fixed.

All graphics drivers are some form of buggy. Not helped that programs/games do thing against specifications.

huh.

More like you having to go all the way back to 8 years ago to find an issue with nvidia, that was fixed in days, rather than lingering for months and years.

All graphics drivers are some form of buggy.

Never said they weren't.
I'm just making a distinction between
hardware/software rife with huge bugs that have hung around for decades. Like Windows, AMD GPUs and Wayland
and
hardware/software with very few bugs, that are very often rapidly fixed no matter how obscure, like Linux, X11/org-server and Nvidia.

plus saying the former isn't recommended or a future anyone will tolerate much longer. But hey, some people believe in windows phone, and I'm not going to stand in their way if they want to bet their house investing in developing for it, maybe it will work out for them.

19 November 2022 with the latest data as of 16 May 2023.

Please find date of AMD benchmarks. " , like from a couple of days ago" is what you asked for the benchmarks those are not from the last couple of days..

https://www.phoronix.com/review/may-2023-linux-gpus/4

Here is the benchmark inside the last couple of days. GTA V does not run at the moment on open source AMD. Fun point open source drivers just implemented some of the optional features that should improve performance of GTA V since it not all that GTA V need to perform well the result is it does not run. Normal failure that happened before.

More like you having to go all the way back to 8 years ago to find an issue with nvidia, that was fixed in days, rather than lingering for months and years.

The race condition bug switching between text based terminal and X11/Wayland that Nvidia suffers from that has not been fixed in decades first appeared 2002. There are quite a few bugs with Nvidia on Linux that have stuck around for decades this is the reason why Redhat and others would like to write their own drivers for AMD and Nvidia and Intel hardware all 3 vendors are slow to address Linux issues like it or not.

Open source drivers have just hit the same fault with GTA V that Nvidia hit 8 years ago when they implemented the same extensions. Don't know what opengl implementation GTA V developers used but it was not AMD or Nvidia by the expected behaviors by GTA V maybe the Intel opengl/dx12 for Xeon Phi yes that a different opengl/dx12 to what intel igpus use or something custom console.

GTA V performance is not wayland problem but there is a interesting issue there.

Only on Wayland, where it has never worked.
Still works fine on X11, terrible CPU perf excluded.

There is actually a merge request to start to address that on X11 vulkan also accepted in the last couple of days

Try again GTA V is busted be it wayland or X11 with AMD at the moment.. There are old X11 vs Wayland were GTA V works on Wayland and X11 with AMD but that has not been the case for a while..
This is why you have to be careful with the combination of benchmarks on the open benchmarking site because total failures are not logged.

Asking for a recent GTA V benchmark on AMD hardware with current drivers on Linux with X11 or Wayland you are screwed. You asked for the impossible and from your responses so far you did not know you asked for the impossible..

https://github.com/zmike/vkoverhead

For those who don't know vkoverhead used in that test report runs without X11 loaded. vkoverhead on Linux clean running the tests are done without X11 or Wayland compositor. So that work is a general improvement not X11 particular.

The RADV developer there works for Valve that work is not X11 focused.

vkoverhead is not in fact designed for testing overhead under X11 or Wayland it designed as something that can be up on the mesa automated test servers to detect issues with very min setup and prep.
