A lot of the improvements are specifically for the Linux platform
The UNIGINE, a real-time 3D engine built to run on all major platforms, including Linux, has just received important updates, bringing some interesting changes.The UNIGINE project is a massive undertaking and it’s already used in some released games, not to mention a lot more titles that haven’t hit the shelves yet.
Among the most important changes in the UNIGINE real-time 3D engine, for Linux, we can identify improvements for dynamic vertex/index buffers, vertical synchronization support, gamma value control, support for a better detection of GLX_ARB_create_context extension, and improved fullscreen mode.
The engine is used on a number of well-known projects such as Oil Rush (check out our review) and Heaven DX11 Benchmark, which also runs on Linux. A comprehensive changelog can be found in the official announcement.
Keep in mind that the UNIGINE graphics engine is only aimed at commercial enterprises and that not even a trial version is available for the general public.
