<pre>Ok, I nailed down the choppyness: source engine games do compile a lot
of shaders live... then a "safe" llvm won't do and will cripple performance.
You must maximize shader compilation performance with threading and aggressive
compilation options for llvm. Vulkan spir-v will be more than welcome.
One down. One to go. Those graphical glitches are also into portal2, but less
visible and more rare.</pre>
