It's really noticeable, and a lot worse than it used to be. My dev desktop is a 5800X with 64G of RAM and a nice samsung m.2 SSD. VS feels slow on it. Rider doesn't. VS Code doesn't.

Especially for large solutions (in terms of .NET development) , VS Code seems much slower than Rider.

Input latency

That’s the thing that makes Visual Studio so annoying. Even typing is slow. A lot of other stuff too.

I use Rider in a Windows VM and it is night and day compared to VS 2019 in regard to speed.
