XInput controller autoconfig is built into the application, with other controller types available as external profiles.*Per-core and per-game configuration overrides*Built-in [https://docs.libretro.com/guides/crtswitchres/ <abbr title="On Windows OS you need CRT Emudriver OR EDID editor tool such as 'Custom Resolution Utility'.">Custom resolution/CRTSwitchRes</abbr>] and refresh rate for video output, with exclusive fullscreen mode and monitor index for multi-monitor setups.*Dynamic rate control for smooth audio and video, even when the game's output rate differs from your system's. Especially obvious with systems like GBA that do not run 60Hz.*Basic fast-forward, SRAM saving, savestate, etc. It supports serialization of the emulation state, which is used to provide real-time rewind and netplay.*[[Shaders and Filters|Pixel shaders]] and [[Shader_Presets|presets]], primarily using Slang, Cg and GLSL, with HLSL on Xbox 360. The shader format it uses is flexible and fairly easy to use, allowing for complex multi-pass effects with adjustable runtime parameters. Also supports traditional video filter plugins that are run in software.*Supports audio DSP filter plugins through .dsp configuration files.*Custom overlay support.*FFmpeg recording and playback support. It can record either the native resolution output of the core or the post-processed output of the frontend. Playback is handled through an internal FFmpeg libretro core.*Streaming support.

It should be lag-free if everyone involved emulates at full speed, doesn't live on opposite sides of the world, and has decent internet speeds. It uses peer-to-peer UDP and supports two players. Due to rollback, it requires a fair amount of CPU power to run, and only works with cores that support serialization.*Options for decreasing input latency related to vsync by eliminating buffering by the video driver, as well as using frame delay to delay polling of inputs until right before a vsync occurs on the display.*Supports [[Input_lag|input lag-mitigating techniques]]. One of these setting is "Run-ahead" which allows cycle-accuracy emulators to run ahead of mandatory 1 or 2 frames of input lag.

*Consistency across multiple systems==Netplay==Netplay is now usable from the menu in current builds, under Settings>Netplay Options. You can get it to work with the [https://github.com/libretro/RetroArch/wiki/Using-command-line command line] or the long-deprecated [https://www.mediafire.com/download/yrydc78bl6y82z4/retroarch-phoenix.7z RetroArch-Phoenix Launcher] as well in older builds.

*Custom resolution You must specify whether you will be hosting (server) or joining (client) the game. If joining, you must also enter the host's IP address in the field below. Make sure your firewall is open on port 55435 (default; you can change it if you like) and refresh rate for outputthat the port is forwarded in your router, if applicable. You can also specify 'spectator mode,' which will allow an arbitrary number of spectators to join and watch you play without being able to play themselves.

*Dynamic rate control for amazing sound even when itDelay frames denote the maximum number of frames RetroArch's run libretro cores will need to emulate at once to maintain synchronization due to actual network latency. You can figure out an appropriate ballpark for this number by pinging the other player and dividing the time (in milliseconds) by 16 (roughly the number of milliseconds in a frame from a different rate than game running at 60 fps). If the videogameplay is a bit choppy, such as vsync causes sometimes. Especially obvious with GBAtry increasing the number of delay frames a bit.

Similar to ==Controversies==A number of controversies have sparked during the GGPO platform, development of RetroArch creates a constant stream of savestates which, along with button presses, are exchanged and compared between the server mostly due to Squarepusher/TwinAphex's attitude and client machinesactions towards upstream emulators.
