Unity 5.3 has been on my radar for one single reason, they finally have a modern OpenGL system! I really hope developers upgrade to it.
QuoteWith Unity 5.3, we’re shipping a number of new features which raise the bar for rendering quality and deliver improvements to rendering efficiency.
For starters, there’s a brand new OpenGL 4.x core, which will replace our legacy OpenGL 2.1 core. This allows you to take advantage of the very latest OpenGL features on Windows, OS X and Linux, whilst also being able to scale to older versions of OpenGL, depending on the user’s OpenGL driver support. Note that in 5.3, Unity will default to the new OpenGL core, but you can switch to legacy OpenGL 2.1 manually to maintain previous behavior. Our current aim is to remove the legacy OpenGL core in Unity 5.4.
See the full announcement here.
I would urge developers to update, as the Linux version should perform better with the new OpenGL system in. I am also pleased to see them aiming to remove the legacy system for the next major update, no point keeping it around.
