Ruffle.exe complains about OpenGL with --graphics dx12 #12139

Describe the bug

I got a win7 virtual machine running on VMWare running on Windows 10 as a hypervisor, and the desktop Ruffle.exe refuse to run on the VM, but the interesting part is that when ruffle.exe is invoked with --graphics dx12 it still complains about OpenGL, not DirectX 🤔 which suggest something is wrong here, is the --graphics argument being ignored? look at this

ruffle.exe

Ruffle does not support OpenGL on Windows.

ruffle.exe --graphics dx12

Ruffle does not support OpenGL on Windows.

ruffle.exe --graphics vulkan

Ruffle does not support OpenGL on Windows.

ruffle.exe --graphics gl

Ruffle does not support OpenGL on Windows.

Expected behavior

not giving an OpenGL error when invoked with --graphics dx12

Affected platform

Desktop app

Operating system

Windows 7 SP1 x64

Browser

No response

Additional information

observed on Ruffle 0.1.0-nightly (a35ea3d9f21706237068a4978bf5044798591656 2023-07-17)

Looks like the error message is incorrect, seemingly introduced all the way back in bbb788ced31c7e125bb6d72d5303880121606f8d and we never noticed 😅

The correct error here would be Ruffle requires hardware acceleration, but no compatible graphics device was found supporting vulkan or dx12

your first mistake was running ruffle on a virtual environment

divinity76 commented 1 year ago

@ActionWavele nah, funfact, VMWare (but not VirtualBox) actually has good GPU support, there are several games you can run in a comfy ~20fps on VMWare, and comparatively ~1fps or outright crash on VirtaulBox. I suspect the problem is that Win7 only support DirectX <=11, while Ruffle needs DirectX >=12

if you insist, though I think VMs are not even considered when they develop this emulator, so you may run into issues like the rest of VM users

An easy way to reproduce this on a typical Windows system is to run Ruffle with -g metal. That will also warn about OpenGL.
