#1Enabling Hardware Acceleration in Electron

Pass Chromium GPU flags in Electron main process:

Electron Hardware Flags
const { app, BrowserWindow } = require('electron');

app.commandLine.appendSwitch('enable-accelerated-video-decode');
app.commandLine.appendSwitch('enable-gpu-rasterization');
app.commandLine.appendSwitch('ignore-gpu-blocklist');

function createWindow() {
  const win = new BrowserWindow({
    width: 1920,
    height: 1080,
    webPreferences: {
      nodeIntegration: true,
      contextIsolation: false
    }
  });
  win.loadURL('http://localhost:3000');
}
