选项页控制硬件加速开关   

1、前端代码

javascript"><settings-toggle-button id="hardwareAcceleration"pref="{{prefs.hardware_acceleration_mode.enabled}}"label="$i18n{hardwareAccelerationLabel}"><template is="dom-if" if="[[shouldShowRestart_(prefs.hardware_acceleration_mode.enabled.value)]]"><cr-button on-click="onRestartClick_" slot="more-actions">$i18n{restart}</cr-button></template></settings-toggle-button>

2、c++代码

​
// Set to true if hardware acceleration mode is enabled on this browser.inline constexpr char kHardwareAccelerationModeEnabled[] ="hardware_acceleration_mode.enabled";​

 chrome\browser\gpu\gpu_mode_manager.cc

// static
void GpuModeManager::RegisterPrefs(PrefRegistrySimple* registry) {registry->RegisterBooleanPref(prefs::kHardwareAccelerationModeEnabled, true);registry->RegisterBooleanPref(prefs::kHardwareAccelerationModePrevious, true);
}

修改此kHardwareAccelerationModeEnabled值即可控制。
