AdvertisementĮspecially if you have multiple high-resolution displays connected to your Mac or if you’re using a system with a relatively underpowered GPU like the Retina MacBook, this can lead to choppy and inconsistent performance. The way OS X handles scaling (making a screen that looks like a 1280×800 display look like a 1440×900 display instead) is cleaner for users and developers than the system Windows uses, but it’s harder on your GPU, which is asked to draw resolutions far beyond your display panel’s native resolution. What we’re hoping is that Metal can help with fluidity and responsiveness on 4K and 5K displays and on Retina screens, especially when they’re being used at scaled, non-native resolutions.

Apple's own apps-Final Cut Pro and the like-are more than likely to pick up Metal support, too.Īside from heavy 3D applications, Apple has also integrated Metal support into Core Graphics and Core Animation-these are responsible for 2D rendering and most of the animation that happens on the OS X desktop. Apple boasted of an 8x rendering performance improvement in Adobe After Effects and companies like Adobe, The Foundry, and Autodesk. This can simultaneously speed up graphics while also leaving the CPU free to handle physics calculations, AI, or other things the GPU can't do.Īpple's sales pitch for Metal leans primarily on the gaming use case, outlined above, and for professional apps that use 3D rendering or GPU compute. Metal's primary function is to move some of the processing load from the CPU to the GPU to alleviate bottlenecks, particularly those related to draw calls. Metal is another feature imported from iOS, a graphics and GPU compute API designed to eliminate some of the overhead of OpenGL and OpenCL. So we're not looking at an iOS-esque level of system lockdown just yet, though there are no promises that System Integrity Protection won't become mandatory in some future version of OS X. There's a new item under the Utilities menu that will let you toggle System Integrity Protection on and off for El Capitan volumes.

If you do, reboot into your El Capitan Mac's recovery partition. If you never dive into any of those folders, you won't notice the difference in day-to-day usage. That's one way to protect important operating system files from external tampering! Not even administrators can add to these folders or edit files that are in them, though they retain their access to the rest of the files on the drive. This list includes /System, /bin, /usr ( but not /usr/local), and /sbin.
#Osx opengl 4.3 drivers
I know my graphics drivers only support 4.2 right now, but I had thought that GLX was designed to throw an error, give a NULL context, and let your program keep going, but instead it can't get past the failed creation of the context.System Integrity Protection, also called "rootless," is a new system security feature that prevents the user or any process from writing in system-protected folders. The method I use (#2) fails immediately upon creation of the 4.3 context.
#Osx opengl 4.3 trial
Using trial and error, where I start from the newest version (4.3, but my GTX 460 only supports up to 4.2, even though I updated the drivers), and if that fails (which I detect by checking for SDL to return a NULL context), I lower the version number and try again. There are two methods I can think of:ĭetecting the latest supported version of OpenGL and using that, but I can't think of any way to do that.

This way I can use the newest features of OpenGL where they are relevant and useful, but also support older hardware.
#Osx opengl 4.3 driver
I'm using SDL2 and C++11 to build a game engine (just as a personal project, for fun and for practice), and one of the things I want to do is try and have the graphics driver use the latest supported version of OpenGL, and vary how the graphics portion of the engine renders based on the version.
