Hardware acceleration refers to when a software uses support from computer hardware in order to speed up processes, namely those that are repetitive in nature. Google Chrome does this. However, you may disable it at any time.
Open Google Chrome, and click Customize and Control Google Chrome > Settings > Show advanced settings. In the System section, uncheck the box next to Use hardware acceleration when available, and restart Google Chrome:
N.B. Upon disabling hardware acceleration in Windows 8/8.1, you won't be able to use Google Chrome in Modern UI mode.
