Introduction.
After Visual Studio 2012 was released with a new static analysis unit included in all of the product's editions, a natural question arises: "Is PVS-Studio still relevant as a static analysis tool or can it be replaced by the tool integrated into VS?". A detailed answer with examples is given in this article. We have performed interface and usability comparison as well as a comparison of error diagnosis strength in real software code. The comparison was carried out on the source code of three open-source projects by id Software: Doom 3, Quake 3: Arena, Wolfenstein: Enemy Territory.
