As far as I understand it, Visual Studio is the de-facto standard for Windows development in C# and C++, but it is limited by the fact that it's a 32-bit application and thus only has access to 4 GB of RAM for loading projects (Microsoft wrote a blog post 10 years ago explaining(?) why there is no 64-bit version). AAA games, however, are dozens of GB large, and even after factoring out the assets (which VS doesn't load), still amount to quite a bit of executable code.
Are AAA developers able to work within those limits for PC development, or do they use other IDEs that have 64-bit versions?
(I am aware that Visual Studio often uses out-of-process facilities for actually building and running projects, but the IDE itself is 32-bit and a lot of its functions, such as CodeLens, run in process).
