I wonder what the resource usage of this will be. ReSharper with C# really slows things down on my machine. With an SSD it's fine, but with a regular HDD I notice the difference.

Hmm, interesting how it compares to VisualAssistX (a plugin for Visual Studio that has been around for a very long time). Hopefully someone will blog a thorough comparison soon.

I had to uninstall one of the later beta builds because leaving any C++ Visual Studio solution open would result in a massive multi-gig memory leak. VisualAssistX is still installed because it's lightweight and though it doesn't have the same featureset as ReSharper, it doesn't get in the way. Don't get me wrong though, I'm still willing to try RS again.

Looks good but I will stick to VisualAssistX as it is cheaper, at least in the UK.

Can't figure out if it works with my CUDA, QT, CGAL.

First of all ReSharper C++ offers ~60 real-time code inspections. Things like unreachable code, hiding local declarations, dependent type without 'typename' keyword, non-inline function definition in a header file, boost::format with too many or too few arguments, invalid printf format specifiers, redundant keywords ('else', 'static', 'template' etc).

Quick-fixes are provided for many of the inspections so that if you want to act on an inspection, you can have R# C++ do the editing for you.

AFAIK Visual Assist has very limited code analysis capabilities.

Refactorings/transformations such as "Substitute macro call", "Initialize field from constructor parameter", "Merge nested if statements", "Replace redundant parentheses", "Move method implementation out of class scope" or "Replace 'auto' with explicit type" are also unique to ReSharper C++ AFAIK.

Also I don't think VAX has navigation to derived/base symbols or specializations.

Some of the things that VAX has but R# C++ doesn't include Document method, auto-inserting underscores after 'm' and Header hierarchy view.

Here's how a dev on the R# C++ team has summarized differences between the tools in a comment last year: http://www.reddit.com/r/cpp/comments/29k4fb/resharper_for_c_...

(Disclaimer: I'm with JetBrains, the company behind ReSharper C++. If you want to take the above with a grain of salt, feel free to.)

Mixed comments on resource usage so far. Some examples: * "Besides beeing a bit slow, VS suddenly felt like a proper IDE" * "a bit more sluggish than using vanilla VS, but made up for it in terms of usability" * "even after I've opened the project and everything is parsed, Visual Studio slows down too much for it to be acceptable" * "once resharper had completed (warning up) though, everything was fine and Visual Studio + performance was pretty good"

(these are all from a recent reddit thread: http://www.reddit.com/r/programming/comments/31xbrt/jetbrain...)

Seems that it depends on the size and complexity of a solution, takes trying to see if it's acceptable in a given environment. That said, a lot of performance work is ahead provided that the team has input on what's going wrong and in what circumstances.

That's exactly why I uninstalled Resharper. I loved the extension, and was quite seriously considering paying the cost of admission ($149), but it just dragged down Visual Studio 2013, both in terms of start times and I also had random second-long freezes throughout the day. This disappeared as soon as I uninstalled it.

It appears like Visual Studio 2015 has many of the Reshaper features I most covet, and doesn't appear to have the same performance issues (likely because they're powered by architecture changes), so win/win, and I save $149 since my employer gets us MSDN.

You should consider CodeRush from DevExpress. They've always been super serious about performance (they have perf stats on their site). They've had C++ tooling for years, their UI is top notch and their live templates blow R# out of the water.

I'm not affiliated with them in anyway, but I am a huge fan.
