Vulkan error (VK_ERROR_OUT_OF_HOST_MEMORY)

Toxe

komandor_353 Hmmm, I think your best bet is to open an issue on GitHub or check the existing ones (I just saw a couple issues with Vulkan errors like this one). Also try using an older or newer version of the engine if possible.

kuligs2

try native godot version 4.4

komandor_353

kuligs2 I tried it, but alas, the error remains.

kuligs2

komandor_353 can you create new empty project with that new renderer?
can you then paste your code into the new project and see if it maybe work there?

komandor_353

kuligs2 No, alas that didn't help either.

komandor_353

I will give my code to a friend and see if it works for him. And if I get any results, I’ll post it here.

All in all, the results of this testing are very interesting. In general, loading the game and its operation requires 6-7 GB of RAM. I gave this code to 3 friends:
1) 4070, 12 GB video memory and 16 GB RAM - no error
2) Me, who has a 1060, 6 GB of video memory and 48 GB of RAM - there is an error
3) 1050TI, 4 GB video memory and 16 GB RAM - there is an error
4) Intel Core i5 1235U, Integrated Graphics, Iris Xe Graphics (80EU) and 16 GB RAM - no error.

I can see the crash on weak NV cards. Apparently video memory is needed here. The most interesting thing is how Iris Xe takes memory — any stats?

komandor_353

I also tried the tiny model and it runs without error

Might be best to report on GitHub.

Tomcat

komandor_353 until the Godot developers themselves do automatic swap, like in UE5

It can be suggested

I can't give any statistics yet, but as far as I understand, Godot can't automatically "swap" files from RAM and VRAM and back.

komandor_353 Godot can't automatically "swap" files from RAM and VRAM and back.

Godot can't. But Iris XE, as far as I understand, that's exactly how it works — the video driver does it.

komandor_353

That's why when Forward+ initially loads, it tries to shove everything into VRAM, it fails and it breaks. And if that's the case, then the only way to do it is to write to the developers so that they add automatic swap, or tell from them to us about methods for controlling file loading. But I could be wrong about all this.

komandor_353

Tomcat I think in case of integrated graphics core everything is simpler. For it RAM and VRAM are the same, so everything works well

Tomcat

komandor_353 For it RAM and VRAM are the same, so everything works well

Then it turns out that for the game, you need VRAM to avoid crashing.

komandor_353

Tomcat Yes, or somehow learn to control loading and unloading in VRAM, until the Godot developers themselves do automatic swap, like in UE5

komandor_353

Tomcat But to be honest I don't know where to write. Is there some kind of developer email or how to specifically contact them?

kuligs2

komandor_353 good luck, just open an issue on github and hope for the best.

So there was no issue at all, the godot did what it was supposed to do, warn people that run out of juice. And maybe you need to optimize the code to run on potatos?

Bug reports

As a tester, we encourage you to open bug reports if you experience issues with this release. Please check the existing issues on GitHub first, using the search function with relevant keywords, to ensure that the bug you experience is not already known.

kuligs2 Well, the funny thing is that if you use gl_compatibility, there are no problems with rendering (there is another one), it just loads all the meshes into RAM and doesn't complain about anything, but with Forward+ the problem above appears

komandor_353 but with Forward+ the problem above appears

Apparently, with Forward+ he expects you to have a decent video card (well, one that he considers worthy) and gets very offended if it is not.
