check if Current OS support argument

[wnunezc]

Any Way to check if Current OS support argument like:

CefSettings settings = new CefSettings();

settings.CefCommandLineArgs.Add("in-process-gpu");
settings.CefCommandLineArgs.Add("use-angle", "gl");

in mi dev Laptop with windows 11 it work well when i test the release executable in other PC with windows 10, it is automaticaly Closed.

Any Way to check if Current OS support argument like:

Not to my knowledge. You would have to manually test with all os/hardware combinations you wish to support.

Hard coding specific GPU settings is not recommended, it's best to make sure your app has an app.manifest and let Chromium decide what best suites your hardware.

Also it's my understanding that in-process-gpu is only for testing purposes on Windows. Use as your own risk.

If you are trying to specify GPU command line args for the purpose of taking a screenshot then that's entirely unnecessary now. Use https://cefsharp.github.io/api/102.0.x/html/M_CefSharp_WinForms_ChromiumWebBrowser_CaptureScreenshotAsync.htm

and i think that cant implemente app.manifest to handle it becouse i am using .net 4.5.2 and that you say is working in .net 4.7 or higger

Not true.

ok i am crazy...

You can still configure DPI Awareness via the app.manifest in older versions of `.Net. Newer versions do have better support, doesn't mean that older versions have none.

Use https://github.com/cefsharp/CefSharp.MinimalExample/blob/master/CefSharp.MinimalExample.WinForms/app.manifest and change assemblyIdentity.

with my manifest:

With your manifest:

adding the manifest of your minimal example doesn't help me at all...even the frame rate drops abruptly...

@amaitland well I have tried to do my best and the main idea is to show this to the User:

As you can see I am offering the user the hardware acceleration that CefSharp offers and CEF...

CefSettings settings = new CefSettings();

settings.CefCommandLineArgs.Add("in-process-gpu");

switch (index)
{
	case 0:
		settings.CefCommandLineArgs.Add("use-angle", "gl");
	break;
	case 1:
		settings.CefCommandLineArgs.Add("use-angle", "gles");
	break;
	case 2:
		settings.CefCommandLineArgs.Add("use-angle", "d3d9");
	break;
	case 3:
		settings.CefCommandLineArgs.Add("use-angle", "d3d11");
	break;
	case 4:
		settings.CefCommandLineArgs.Add("enable-features", "Vulkan");
		settings.CefCommandLineArgs.Add("use-vulkan", "1");
	break;
}

the problem is that I need to test if the selected version works correctly at the moment the user selects one of them. and prevent the program from breaking and not being able to reopen...

[wnunezc]

the main reason that an option of this does not work; it is because the OS does not support it or CEF or CefSharp does not find locally the support to provide the selected hardware acceleration; I cannot create an executable for each version and have the end user download N amounts of executables that vary because an option cannot be tested or validated.
