C++ is known to be a very powerful language. C++ allows you to have a lot of control as to how you use computer resources, so in the right hands its speed and ability to cheaply use resources should outperform other languages. The Unreal Game Engine is the most popular engine for building AAA title games, which are primarily built with C++. Though, if you want to take advantage of Unreal's graphics-rendering capabilities, you naturally need a large budget.
