Not detecting gpu

[molor824]

Bevy version

Bevy 0.6.0

Operating system & version

Windows 10

What you did

Compile a code that uses quad mesh in release

What you expected to happen

Run smoothly

What actually happened

Fps very unstable, input delayed and in the log, it was using 'Microsoft basic driver' and not the gpu

Additional information

Tried changing WGPU_BACKEND to every different backends (gl, vulkan, dx11) and only dx12 works but still using cpu to render

I have a similar issue. I'm on Windows 11 with an Nvidia GPU. DX11 and Vulkan backends don't run, DX12 backend runs for a while but FPS is unstable and it eventually crashes.

DX11:

thread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers!', C:\Users\adam\.cargo\registry\src\github.com-1ecc6299db9ec823\bevy_render-0.6.0\src\renderer\mod.rs:74:10

Vulkan:

DX12 backend runs for a while and eventually crashes with:

I had the same issue on my laptop. I have 2 GPU (one from my cpu and my main gpu)

Normally if you disable one of your graphics card (in Windows : Device manager > Display adapders > Disable device) it should work.

However it worked when I tried to use the Vulkan backend like this : (using bevy 0.6)

use bevy::prelude::*;
use bevy::render::options::{Backends, WgpuOptions};

fn main() {
    App::new()
        .insert_resource(WgpuOptions {
            backends: Some(Backends::VULKAN),
            ..Default::default()
        })
        .add_plugins(DefaultPlugins)
        .run();
}
