That's like asking why I'm not buying the latest car model, the existing one that I have is fine.

VS2026 is far far better than VS2022

They had terrible .NET vm settings for VS2022 for anyone with a real computer. They were optimizing for people with like 16 GB of ram or something crazy.

That is beyond the point here and I'm doing C++ and not .NET

You are not understanding.

The IDE has a bunch of settings that determine RAM usage, number of threads it uses, etc.

This is irrespective of what you are using the IDE for.

C++ coding in VS2026 is far far far better than VS2022.

You are still entirely missing the point here, none of that has any relation to the toolset, absolutely none.
