### What are the LLE options for? Should I enable them?
LLE stands for [Low Level Emulation](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/wiki/Overview-of-the-project-&-Glossary-of-terms#lle).
As of [582b39e](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/commit/582b39e3c7531845af966263ae768cddb56a4218) only LLE GPU is implemented.

Enabling this option will emulate the Xbox's NV2A GPU using OpenGL instead of passing calls to DirectX.

It may provide more accurate results, but is currently much slower than the default HLE approach.
That is not inherent to LLE, but the way it is currently integrated in Cxbx-Reloaded.
As of PRs [#1365](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/pull/1365) and [#1532](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/pull/1538), LLE USB is completely implemented but cannot be enabled, due to timing issues when connecting more than one controller to the virtual Xbox. Enabling this option will emulate the underlying USB hardware of the Xbox instead of intercepting XInput function calls.

As of PRs [#1572](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/pull/1572) and [#1561](https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/pull/1561), LLE networking (using [XQEMU](http://xqemu.org) code) is completely implemented. This adds support for system-link play. This feature is enabled by default, but must be configured.
There are other Xbox emulation projects that are focused entirely on the LLE approach, like [XQEMU](http://xqemu.org) and [MAME](https://www.mamedev.org/).
Due to a lack of kernel emulation in those projects, you will need ROM files from a physical Xbox. Cxbx-Reloaded is easier to use, because it has kernel emulation and does not require these files.
