yep, high end hardware.
btw, mesa-23.2.1 will release this week.

Ha ha, I doubt we will have hardware raytracing on the Pi4, would be cool on a Pi5 ;)

PiCore Linux 14 has been released and vkcube runs real fast on that ;)
If only flwm did dual screens :(

Rpi4/v3d supported vulkan-1.2, maybe 1.3 can do this.
or, wait this to come.

Been quite some advances in V3DV Vulkan, mostly developed with the help of Intel Tile Engine GPUs :D
Virgl, Zink etc might mean Doom in QEMU on Pi's?

How much more can be off loaded to the 2GHz+ quad Arm8V NEON enabled CPUs?
Unless Pi5 has a super enhanced VideoCore this will help improve Desktop performance for Pi5 gen products.

I did notice some Broadcom chips are Vulkan 1.3 certified, just no idea where they are used or who is using them.

NO, you need notice Vulkan api version, vulkan-info

@Moonmarch, gzdoom had 4.11.0-arm64.deb build :D

sorry, my mistake, saw it was arm64 :(

mesa-23.2.1 released.

GZDoom was updated to 4.11.0, nice catch cjan.

I will build the software when I have a chance.

Bookworm released Mesa 23.2.1-0+rpt2.

Vulkan renderer does run on the Raspberry Pi 4 computer with the latest build of GZDoom, but I am not sure if the Vulkan renderer is actually activated, and is changing back to GLES renderer, because the performance has not improved.

I will update the GZDoom DOOM Engine Source Port on the Raspberry Pi 4 Computer build guide when I have the chance to include the new software libraries required for the latest release of GZDoom.

I still have to install the Raspberry Pi Operating System Bookworm update, and I will be busy with even more projects.

Been playing a few Vulkan games now, they work on Bookworm on Pi400 with all the updates which include newer mesa.
Some more mesa commits over the weekend are Pi5 related?

last build git-4.12pre+61, vulkan failed.

Might be why 23.3 got committed?

Now that Bookworm is out n some have Pi5's a bunch of wrinkles are getting ironed out.
Fix one thing, break another.
Bleeding edge, pack bandaids :lol:

my build included mesa-23.3 git( RPi-5-VideoCore-7.1.x), vkdoom-git fail too.

Pi4 sway/wlroots/wayland/gzdoom-git/mesa-git-23.3/kernel-6.6-rc6.

MESA_LOADER_DRIVER_OVERRIDE=zink gzdoom, run pretty well.
but does zink work or not?

MESA_LOADER_DRIVER_OVERRIDE=zink glxinfo | grep OpenGL

I have upgraded to Raspberry Pi Operating System Bookworm, and the performance with the latest version of GZDoom has improved substantially on the Raspberry Pi 4 computer, which is now capable of running GZDoom mods.

Now I have to rewrite the GZDoom build guide for the Raspberry Pi 4 computer.

UPDATE NOVEMBER 14TH 2023

• Updated Build Guide to support Debian Bookworm update.

• Removed GZDoom OpenGLES Renderer support from Build Guide.

• Added new software releases explanation.

• Updated software dependencies list.

• Added 2 new screenshots, and removed previous screenshot.

• Revised DOOM Mods explanation.

• Added download links to Brutal Doom Community Expansion DOOM Mod, and Doom Retribution WAD.

• Removed LZDoom explanation, and removed link to (OUTDATED) LZDoom Build Guide.

• Removed (Outdated) PrBoom-Plus 2.5.7.1um explanation, and Build Guide with PrBoom-Plus 2.6.66 Build Guide.

• Miscellaneous improvements.

be aware this, they not commit yet.
https://gitlab.freedesktop.org/mesa/mesa/-/issues/10111

Looks like a big bug fix is due.
As soon as they figure it out ;)

No hurry for me, don't have Pi5 yet and Pi400 with Bookworm is okish for normal non game stuff.

Don't want to hijack here, but that looks like the issue I've been seeing trying to build Duke3D and wolfenstein.. .

I have tested this out on Raspberry 5 and these instructions are still applicable though short of housekeeping details after the engine is built. The Raspberry Pi 5 is capable of running with all graphics set to the highest possible. I have tested it will multiple mods, including the most full featured Doom and Hexen mods and successfully got them to work with all features functional. Make sure you choose Open GL ES as your API as Vulkan is not working correctly with this game and will simply max out your CPU with GPU usage showing near zero and FPS less than 1 FPS. I am not sure why Vulkan works so poorly but it does in this example. No worries though, Open GL ES will give you every feature you need to get the best out of GZdoom

I have been extensively testing this Hexen mod known as Hexen - Rebirth of Chronos.

https://www.moddb.com/mods/hexen-rebirt ... version-09

Yes, the Pi 5 can indeed run it with full setting all of the graphics shown in the screen shots and videos. It can do it without skipping a beat. There were some tricks to get it to work correctly though. It is finicky about loading order of PK3s and you need set Precache GL textures and set Sector Light to Vanilla. Make sure you do these setting from running hexen.wad. Save your setting and close the game. Then reload it as follow with the PK3 and the wad file in your GZDOOM directory:

./gzdoom -file RebirthofCronos_1.pk3 RebirthofCronos_2.pk3 RoCMaps.wad -iwad hexen.wad

Get ready to see Hexen at the most glorious you ever seen it. You must load the pk3s in that order as it will not work otherwise. It took me a while to figure that out as no instructions anywhere indicate that. Let me know if you test this out on Raspberry 5 and how you liked it. I will post about how to use the most advanced Doom mods in my next post. We may as well enjoy GZDoom at it's full capability and Raspberry Pi 5 has enough grunt to deliver the best GZDoom can do. Enjoy

I have to admit I did not expect Raspberry Pi 5 to be able to deliver on the Rebirth of Chronos mod. I was pleasantly surprised and you can max out everything and it will play fine. Absolutely beautiful and the Pi 4 was definitely unable to do this. Videocore 7 may deliver quite a few more surprises and Igalia is still working on further performance tweaks that may be able to eek a little more out of it. The Pi 5 is the very first time that Raspberry Pi could remotely claim one of their SBCs as a desktop replacement, because it definitely is getting very close and being able to run the hardest core GZDoom feature mods is proof that it can exceed simple light duty gaming at this point.

Just in case you cannot get the performance I am able to get, there are a few caveats to mention. I have overclocked my Pi 5 in an Argon One V3 case. I managed to get to 3ghz on CPU and 1ghz on GPU. The Argon One V3 also has the ability to add a DAC board to the case. I am using an Argon BLSTR DAC for sound output. I am not sure if the DAC takes load off the CPU or not to help increase performance. The same case uses the PCIe port to allow installation of an NVME in the bottom part of the case. That definitely helps with the load times of the larger mods.

One other thing I should note is that I am using just the regular Raspberry Pi OS. I could not get my BLSTR DAC to work in Ubuntu yet. I haven't put much effort into it yet as the newest version of Raspberry Pi OS meets most needs anyway.
