I'm using Visual Studio 2010 Beta 1. Intellisense is SO SLOW. There's a good half a second delay after I press any key in the source code window. This is absolutely crippling to my development speed. Is there anything I can do to speed up Intellisense? I lost my Visual Studio 2008 key :(.

            Can you use an express version (rather than a beta edition since you lost your key)? They are free and very zippy, but don't support some of the essentials like ReSharper.

            Don't use the beta man. You're better off using the express ed of 2k8.

            Like was mentioned in the comments, the language matters. Nevertheless, I bet the following (do all of them) get you moving again. I plan to go back to my preferred settings with Beta 2 and see if things have improved.
- Set your Windows appearance to Windows Classic. I don't like it either. Do it.
 - Tools > Options > Text Editor > C# > Advanced > Uncheck "Highlight references to symbol under cursor". Additional note: I've confirmed with the C# IDE team that this has been moved to a background thread and had it's thread priority dropped for Beta 2.
 - Close text editor windows you aren't using, and restart Visual Studio periodically (I do about once/day on purpose and 2-10 times/day from crashes - my project is a far edge case that breaks it often).

            I do not know about VS2010 but VS 2005 would have that problem I beleive when C++ was being used. To fix it I had to stop intellisence from running by renaming Feacp.dll .
