Epic Games Launcher

Simply opening the EGL causes my CPU to hit 100% on all cores. Tested under Windows 10 though and the result seems to be the same.

I'll keep an eye on it.

I see: it has very high CPU usage when the main window is open, but drops to practically nothing when minimised. There's something horribly wrong with it and I would guess it is due to CEF trying to use hardware acceleration.

I call BS on anybody pretending to give a platinum rating to any chromium-derived application ngl.

I fully concur with this. There's no way this app is Platinum with all the bugs logged against it.

In Wine-6.0 creating desktop shortcuts directly from launche doesn't work because of:
IShellLinkW interface is not yet supported by InternetShortcut

So I found a way to create desktop entries manually:

1. Open C:\ProgramData\Epic\EpicGamesLauncher\Data\Manifests directory
2. Search/grep through *.item files and find one for wanted game, then copy its AppName field. For example, to find Rocket League:
$ jq 'select(.DisplayName | contains("Rocket League")) | .AppName' *.item
"Sugar"
3. Create/edit .desktop file for EpicGamesLauncher.exe and add "-com.epicgames.apps/${AppName}?action=launch&silent=true" to command line, for example:
wine "C:/Epic Games/Launcher/Engine/Binaries/Win64/EpicGamesLauncher.exe" -SkipBuildPatchPrereq -opengl "-com.epicgames.apps/Sugar?action=launch&silent=true"

Edit:
com.epicgames.launcher :// apps/
(without spaces. too lazy to fight the markup, sorry).

After installation (fresh wineprefix) launcher was crashing during startup (with -SkipBuildPatchPrereq), installing DXVK 1.7.2 fixed it, but after completed logging-in the main window is black and completely unusable, just the friend list window is okay: i.imgur.com/HDrJjJY.png

All the Visual C++ Redistributables and dotnet35 are installed.

Wine-staging 5.18.
Manjaro Linux.
Intel HD Graphics 520.

When you first launch a game after downloading many games will automatically start installing. NET and DirectX.

Unfortunately the .NET installation procedure fails under wine and installing DirectX messes with wine's own implementation. It is better to click cancel on these installers, and install .NET and DirectX/D3D libraries as needed via winetricks.

This is only needed the first time you click to launch a game.

Run winetricks dotnet40 and then go into winecfg and set it back to windows 10, it'll get past the error message. On the login screen it doesn't show any text, but the 4th one from the right is the button you press.
