Default macOS builds -- ICC (normal) vs LLVM/clang

macOS pre-releases on landoleet now have both traditional ICC builds and LLVM/clang builds for comparison purposes, if you macOS users could do some testing and performance comparisons that would be great. Discuss here!

The -clang versions do not have QuickTime video support (which is ancient and deprecated by Apple), and do not currently include PPC bridging support.

The biggest benefit of the -clang version is that it can be made using a newer macOS SDK, which allows OpenGL 3.2 to be used, which should improve the video playback performance (the Video Window, that is) as well as possibly the drawing performance of plug-ins that use OpenGL

Just installed the clang version.

I wonder if this version also would improve "global" GUI performance in Reaper,
so more smoothness when moving track volume faders, dragging items, dragging midi notes, zooming , etc.

OSX 10.13.2.

Just tried the project I'm working on, and definitely have better fps on playhead and meters. Lag behind cursor when dragging a time selection without snap looks unchanged though (even though fps is improved on drawing out the selection itself).

Waves GUI's were the only slightly glitchy ones I have (VST3), and all those issues look to be resolved now (white outlines when turning knobs, and mouse drag behaviour when doing so kind of stiff and off).

Definite progress!

It would be more meaningful if you made your own based on real-world use or so...
