chrome硬件加速

Google Chrome comes equipped with hardware acceleration, a feature which takes advantage of your computer’s GPU to speed up processes and free vital CPU time. However, sometimes driver incompatibilities can cause this feature to misbehave and disabling it could save you a few headaches.

Google Chrome瀏覽器配備了硬件加速功能，該功能可以利用計算機的GPU來加快處理速度并釋放重要的CPU時間。 但是，有時驅動程序不兼容會導致此功能出現異常，將其禁用會為您節省一些麻煩。

什么是硬件加速？ (What is Hardware Acceleration?)

Hardware acceleration refers to when a program uses a computer’s hardware in support to perform some functions more efficiently than capable in the software. The hardware was designed to perform some functions faster than software running on the CPU alone.

硬件加速是指程序使用計算機的硬件來支持比軟件更有效地執行某些功能的情況。 硬件的設計目的是要比僅在CPU上運行的軟件更快地執行某些功能。

In Chrome, hardware acceleration utilizes your computer’s graphics processing unit (GPU) to tackle graphics-intensive tasks, like playing videos, games, or anything that requires faster mathematical calculations. Passing off specific tasks gives your CPU a chance to work tirelessly on everything else, while the GPU handles processes that it was designed to run.

在Chrome中，硬件加速利用計算機的圖形處理單元(GPU)來處理圖形密集型任務，例如播放視頻，游戲或任何需要更快數學計算的事物。 通過執行特定任務，您的CPU有機會不懈地在其他所有事情上工作，而GPU則處理它設計為要運行的進程。

While this does sound great in most cases, sometimes hardware acceleration can cause Chrome to lag, freeze, or crash—it could even cause your laptop’s battery to drain a lot faster. As everyone’s computer is slightly different, the issue could lie in the GPU or driver associated with it. If you suspect hardware acceleration is the culprit, the best thing to do is to disable it and see if that fixes the problem.

盡管在大多數情況下聽起來確實不錯，但有時硬件加速會導致Chrome滯后，死機或崩潰-甚至可能導致筆記本電腦的電池消耗更快。 由于每個人的計算機都略有不同，因此問題可能出在與之關聯的GPU或驅動程序上。 如果您懷疑是硬件加速的罪魁禍首，最好的辦法是禁用它，然后查看是否可以解決問題。

如何打開或關閉硬件加速 (How to Turn Hardware Acceleration On or Off)

By default, hardware acceleration is enabled on Chrome, so let’s look at disabling it first.

默認情況下，Chrome啟用了硬件加速功能，因此讓我們先來看一下禁用它。

Fire up Chrome, click?the menu icon, and then click on “Settings.” Alternatively, you can?type?chrome://settings/?into the Omnibox to go directly there.

啟動Chrome，點擊菜單圖標，然后點擊“設置”。 另外，您也可以在多功能框中輸入chrome://settings/ ，以直接轉到此處。

In the Settings tab, scroll down to the bottom and then click “Advanced.”

在“設置”標簽中，向下滾動到底部，然后單擊“高級”。

Scroll down to the System section and find the “Use hardware acceleration when available” setting. Toggle the switch to the “Off” position and then click “Relaunch” to apply the changes.

向下滾動到“系統”部分，找到“在可用時使用硬件加速”設置。 將開關切換到“關閉”位置，然后單擊“重新啟動”以應用更改。

Warning:?Make sure you save anything you’re working on. Chrome reopens the tabs that were opened before the relaunch but doesn’t save any of the data contained in them.

警告：請確保您保存所做的任何工作。 Chrome瀏覽器會重新打開在重新啟動之前打開的標簽頁，但不會保存其中包含的任何數據。

If you’d rather wait to restart Chrome and finish up anything you’re working on, just close the tab. Chrome will apply the change the next time you close and reopen it.

如果您想等待重新啟動Chrome并完成正在處理的任何事情，只需關閉選項卡。 Chrome會在您下次關閉并重新打開時應用更改。

To confirm it has been fully disabled, type chrome://gpu/ into the Omnibox and hit Enter. When hardware acceleration has been disabled, a majority of the items under “Graphics Feature Status” will read “Software only, hardware acceleration disabled.”

要確認它已被完全禁用，請在多功能框中輸入chrome://gpu/ ，然后按Enter。 禁用硬件加速后，“圖形功能狀態”下的大多數項目將顯示為“僅軟件，禁用了硬件加速”。

If you’re looking to enable—or re-enable—hardware acceleration, head back to?chrome://settings?and toggle?“Use hardware acceleration when available” setting to the “On” position. Then, click “Relaunch” to apply the change.

如果您要啟用(或重新啟用)硬件加速，請回到chrome://settings然后將“在可用時使用硬件加速”設置切換到“開”位置。 然后，單擊“重新啟動”以應用更改。
