Is there any way I can speed up Visual Studio 2017’s autocomplete suggestions / Intellisense?

Hi @KenN-4883 ,

Welcome to Microsoft Q&A!

Have you installed any extensions that are slowing Visual Studio down? You can temporarily disable them under Tools > Extensions and Updates > Installed.

Meanwhile, please free up your disk space and ensure enough memory is available. You can clean the %temp% folder and delete the hidden .vs folder in the project folder.

Besides, if you have hardware acceleration enabled, or if you use the default visual experience settings in Visual Studio 2017, you may experience intermittent performance issues, product crashes, or rendering issues. You can uncheck Automatically adjust visual experience based on client performance check box by Tools > Options > Environment > General.
