Can't open due to graphic cards issue. #8

Closed mechPenSketch closed 10 months ago

mechPenSketch commented 1 year ago

When I tried to open this software, I got this error message instead: trombone I used trombonecharter_win64.exe 0.9.5 on Windows 10 (base operation x64). For graphics, I'm using AMD FirePro W5100 (FireGL V), which is most likely the cause.

Turns out my GPU can't run Vulkan, which is what Godot 4.0 only renders in thus far. However, compatibility with OpenGL is in progress, I only have to wait until it's fully implemented.

It looks as if this is still an issue in 4.x, but I think the more preferable option would be to provide a separate OGL build for people who can't run Vulkan and have the build using Forward+ be the main one. When 4.0 was still in beta I tried the compatibility renderer and it made the program straight up unusable, and even though I'm sure all that's been fixed now I don't see the benefit in a complete switch (there'd likely be performance implications, at the very least)

I didn't know this at the time, maybe I should've looked into it a bit more than I did, but you can load the existing build with --rendering-driver opengl3 in the terminal and it will use OpenGL as the renderer. I just had to do this testing the Linux build on a laptop and it worked perfectly (though I didn't try loading TTFAF, which is what I've generally used as a stress test. Just didn't bother copying it to that computer tonight). So that's great—no separate build is even needed, and clearly OpenGL in Godot 4 has made massive strides since a year ago. In future builds I'll include a script (.bat/.cmd for windows, .sh for linux, i'll probably ask DerpyChap about Mac) to launch the program using this option.

EDIT: This has been open long enough I had forgotten about the part where it says your graphics card also doesn't support the supported OpenGL versions (read: 3.0). I still have yet to try this with OpenGL 2.0, then, and see how well it works—I'll try to do that tomorrow. Just a bit odd that on the Linux build it told me to try flipping that switch and then on the Windows side it clearly tries checking if OpenGL 3 is supported. Maybe it would've given me a different error message if that laptop didn't support OpenGL 3 either?

This is resolved as best as possible by #19 adding an action to export a compatibility build that uses OpenGL 3. Godot 4 does not OpenGL 2 whatsoever (and i'm not sure how exactly i got the idea that it did), but anyone who can't use 3.0 can try the utility DerpyChap mentioned in this comment.
