Unity 5.3 released, hello modern OpenGL system for Linux gaming

By - | Views: 21,956
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. Article taken from

Actually there is a fair change that fps will improve. How much I cannot say,as I am not an OpenGL developer, but there should be some smarter memory management and other optimizations in 4.x extensions, which cannot be done in pre-4.x since hardware is the limitation.
Again I'm not a ogl dev, but by supporting ogl 4.x it might indicate better overall support of ogl - at least thats what I hope :D

Cracking news. Yep get updating devs. ( easy for me to say from the sidelines of course ).

It _could_ lead to more fps, but I wouldn't assume that older titles can just pick up the new version and run with it.
OpenGL 4.x opens up a lot of avenues for improved data handling and for reduced driver overhead. There's also a more options for (relatively) advanced rendering techniques so that things are visually more impressive (and still real-time).

Basically awesome news.

I read that there will be early Metal support in there too, which means they shouldn't have too much work to bring other rendering backends (think Vulkan) once they're available.

Quoting: GuestThere is also the fact that WebGL is an officially supported build target.

Thats actually really good. Would that open up possibilities for games like Quake Live ?

I hope the Cities: Skylines developers are paying attention. We might finally get good performance in Linux.

How easy is it for developers to upgrade? That's my concern here.
