Question

Hello!
I’m making a 3D vtuber model game/program and I have some friends helping me test it out. I’m using forward+ as the rendering method and my friend is experiencing the models turn into a buggy, spazzy, glitchy mess:

when it should look like this, which my other friend gets when they play the game.

I changed it to compatibility mode and it worked fine on my friends(one with the glitchy mess) computer.

I would like to continue using forward+ and so would my friend as it looks better. My friend has given me the specs for his computer and they are provided in the images bellow.

If anyone could give me any information on how I can solve this issue/ whats going on with the rendering engine I would be super appreciative about it. If there is any more detail needed or if you would like access to the actual game file, just let me know. Thank you!

There is a suggestion that the problem lies with the latest drivers from AMD. Try installing the older ones.

There used to be an issue where enabling Enabling MSAA with SSAO on foward+ would causes artifacts on AMD Polaris GPU’s.

So maybe you can try disabling that just to be sure?
The MSAA setting is in ProjectSettings/AntiAliasing (disabled by default)
And the SSAO is inside your environment node.

But it is most likely a bug due to AMD driver update this month.
Here’s the issue track: Meshes rendered incorrectly after AMD graphics card software update · Issue #109378 · godotengine/godot · GitHub

It has already been reported to AMD, and they have confirmed the problem internally too, so it will probably be fixed by the next AMD update.

For now to get around the driver issue, you can change the renderer from Vulkan to Direct3D in the Project settings and that should fix it.
