Godot 4 & Hardware Compatibility & Min. Hardware Req.

Yes, I quoted the statement about windows thinking that would make the context clear. I was indeed referring specifically to windows.

Volkovino I believe that brand new computer and brand new mobiles dependent development does not exactly fit with the Godot "free" philosophy, especially in these economical crisis days and specifically in third world countries.

Your mistake is in thinking that as soon as 4.0 is released that 3.x is invalidated. If you are targeting certain platforms then 3.x is probably the right choice. There's a reason 3.x has been getting not just bug fixes but continued new features of it's own. Indeed it is likely that 3.x won't be discontinued until a 4.x release has become a truly viable replacement.

Yes, I agree with that. I think it's good that Godot is moving to Vulkan for the future, but sadly support is not great on old or lower end devices. Especially for mobile, the hardware and drivers are not mature, and a lot of non-flagship phones don't even support GLES3, let alone Vulkan. Which is why I am using Godot 3.x and GLES2 right now so the game can be played by the most people.

I terms of Godot 4.0, we may be a year away (or longer) before it comes out, so technology will have advanced. And it's likely that Godot 3.x will be supported and maintained for some period even after 4.0 releases. No one has given an exact timeline, but I would guess at least a year, given that Godot 4.0 will not be complete at launch (missing WebGL and some other features).

There is a maybe about Godot 4.1 will support openGL in next stages.

From here: https://godotengine.org/article/about-godot4-vulkan-gles3-and-gles2
"OpenGL support will definitely be implemented by the time 4.1 is out, hopefully some months later."

The GLES3 renderer is already in master, but it's pretty broken and missing a ton of features. Not usable for 3D right now, maybe for a simple 2D game, I don't know. If you build master from source, you can run the Godot 4.0 editor from the command line with this option.

--rendering-driver opengl3

I've tried lavapipe, Godot 4.0 does open, but it's basically not viable. I tried even some 2D stuff and it was so slow I could not use the editor properly and then it eventually crashed. In any case, if your computer is so old it doesn't have Vulkan support, then there is little chance it is fast enough to software render.

Pixophir Is there a software renderer for Windows ?

Yes, you can try SwiftShader, which is a cross-platform CPU implementation of Vulkan. I haven't tried it, but my guess is it would be too slow for serious development. Though perhaps for some simple 2D or PSX-style 3D it would be enough.

Understood. So that's why it says "lavapipe is not a conformant Vulkan implementation. Testing use only." :-)

Thanks. Well, not for me, I was thinking about a workaround for the OP's or possibly other venerable entry level graphics hardware.

Yeah, no problem.

cybereality Godot 4.0 may be a year away from release, so it would make more sense to upgrade when it actually comes out (especially considering that GLES3 support may work by that time)

this also makes sense considering how technology gets cheaper every year:

1 year ago i had bought a laptop for school. it costed 800€ and it's stronger than the 3-year-old (or older) tower i still use at home that had costed 1000€ when i got it as a christmas gift.

2 or 3 years ago i had bought my computer monitor for 500€. it has a 34cm tall SRGB screen with a reesolution of 1920×1080px and a refresh rate of 60Hz. now i have heard reports that some equivelant screns today cost only 300€.

Megalomaniak If one's really on a budget, there's always the gt 1030(gddr version) for ~ 95:

It's not worth it even if it was free. I bought one a few years ago just for testing and it's worse than Intel integrated iGPU. You can barely run 720P 30FPS.

cybereality I bought one a few years ago just for testing and it's worse than Intel integrated iGPU. You can barely run 720P 30FPS.

And yet it's a viable option for a vulkan capable gpu and a noteworthy improvement if you are using a gts 240 or something, but as I said, I'd rather try to find a used gpu that would be in the same price range but significantly better if I was in that situation. Such as an RX 470 4gb, they do occasionally move in that same price range, if you know where to look(such as tech enthusiast forums that have a second hand trade section).

Yes, though if you are going to spend money at least get something that can run at 1080p with low/medium settings. An RX 470 is pretty good and around equal to the RX 6400. Both can do 1080p. Personally, I like buying new, but I see you can get an RX 470 for around $100 on eBay so that's not a horrible deal.

in 2021 i had bought an AMD RX 550
because i experienced bad graphics support on Linux with the pre-installed NVidia GTX 750
and read reports that AMD is the brand with the good Linux support.
at the time i had recently installed Linux on the old tower because it could barely run Windows 10 anymore.

for me it's not a big deal because i fulfilled my goal of better system stability in general, but i can't run Godot 4 (and i still can't run Gdot 4 alpha 11) with the AMD card.

writing this comment, i have the feeling that Godot 4 not starting has nothing to do with graphics.
here is the error log — as a screenshot because it has color:

should i post this error in a issue on Godot's main GitHub repository?

@Sosasees the issue is clearly with pulse audio and the relevant libraries mentioned at the top, libasound.so and libpulse.so

Also, it seems to be finding a project(from 3.x I presume) that it fails to find a compatible project.godot file for. As for posting on github, the latter I believe to be a known issue, but perhaps I'm wrong. Search before you post a new issue, that should be the modus operandi always tho.
