[Fixed] [g4.6pre-65-g6701cd284] Freezes on Apple Silicon (M1 SoC)

[Warrex]

The lastest GZDoom development builds from drdteam.org (gzdoom-g4.6pre-65-g6701cd284.zip, gzdoom-g4.6pre-45-g1767fdfe7.dmg) freeze directly after launch on my Mac Mini 2020 with Apple M1 SoC (Apple Silicon / ARM64).

These builds seem to be compiled as universal apps. When I force macOS to run them through the Rosetta 2 X86 emulation layer everything seems to work fine (just launched Doom2 + Hellbound to see how map 29 runs performance wise).

Btw. GZDoom also freezes when running natively if I do not provide an iwad but then only after hitting "Quit" on the console window.

[Warrex]

The same is true for the last development build of Raze.

Please do a process sampling of GZDoom, and post the report.

Here you go.

I think I found a bug that was causing an infinite loop. A new devbuild with the fix is available.

Great! GZDoom now starts on the M1 natively and with a speed boost of 25% vs. the Rosetta emulation. With the M1s very high ST performance and capable integrated GPU which is on par with a GTX980 or GTX1060 this is a nice setup for GZDoom overall - especially at >30W (https://www.anandtech.com/show/16252/ma ... -m1-tested).

Please also fix Raze! Thank you.

Good.

A bit unrelated request, but did you check Vulkan renderer on M1 running natively?
It would be great if you can do a bench console command a few times with both hardware renderers.
Frozen Time bridge is quite good test case.
It's important to do it at the exactly same location, a saved game helps to achieve this.

[Warrex]

I know the drill (assigned a key, etc.) and everything worked fine but I cannot find the text file. I even gave GZDoom full disk access and searched the whole drive for "bench" finding >100 files but no report of GZDoom. What is the name of the file and where do I find it?

Btw. your wiki still states the ccmd is Windows only.

How do you run GZDoom? From Finder, Terminal, or something else?

[Warrex]

Finder

Screenshots and saves go to Documents/GZDoom as they should.

[_mental_]

The result file is named benchmarks.txt, and it's saved into the current directory.
The problem is, this is the root directory if GZDoom is launched from Finder.
Probably, we should do something with this. Workaround is to run from Terminal.

Moreover, I completely forgot that high resolution time measurement is not implemented yet for Apple ARM64.
So, you can just compare FPS (or better, frame time) for now.

[Warrex]

Even from the terminal it does not work for me. Anyway, here are my results for the attached save file.

Resolution: 5120x2880 (oversampling by macOS for a display resolution of 3840x2160)

Vulkan: 24ms / 42 fps

OpenGL: 29ms / 34 fps

Vulkan with Rosetta Emulation: 36ms / 28fps

OpenGL with Rosetta Emulation: 47ms / 22fps

How does it fare at 1920x1080? With this high resolution it's hard to tell how much of that depends on the CPU and how much on the GPU.

[Warrex]

Vulkan native:
57 fps @ 1080p
64 fps @ 320x200

OpenGL native:
38 fps @ 1080p
39 fps @ 320x200

[Graf Zahl]

Not bad. 57 fps is what I get on my 8 year old desktop as well. That's actually quite a lot better than any other Mac I ever tested.
