 - **CPU**
 
   The CPU emulator, ARMeilleure, emulates an ARMv8 CPU and currently has support for most 64-bit ARMv8 and some of the ARMv7 (and older) instructions, including partial 32-bit support. It translates the ARM code to a custom IR, performs a few optimizations, and turns that into x86 code.  
-  Ryujinx also features an optional Profiled Persistent Translation Cache, which essentially caches translated functions so that they do not need to be translated every time the game loads. The net result is a significant reduction in load times (the amount of time between launching a game and arriving at the title screen) for nearly every game. NOTE: this feature is disabled by default and must be enabled in the Options menu > System tab. You must launch the game at least twice to the title screen or beyond before performance improvements are unlocked on the third launch! These improvements are permanent and do not require any extra launches going forward.

 - **GPU**
 
-  The GPU emulator emulates the Switch's Maxwell GPU using the OpenGL API (version 4.4 minimum) through a custom build of OpenTK. There are currently two graphics enhancements available to the end user in Ryujinx: resolution scaling and anisotropic filtering. These can both be adjusted in the GUI.
