Adaptive refresh with nvidia optimus?

Hey guys,

 

When amd freesync first came out, it was using the v-blank spec on laptops to achieve adaptive refresh rates.

 

Since this spec is available on laptops with nvidia optimus (where the gpu is connected to the igpu when then goes to the monitor), why is gsync only on laptops without optimus/ desktop replacements.

 

I tried doing research on it, but the only thing that came up was that incident that happened on early 2015 where a leaked driver allowed users of a certain asus laptop to have gsync capabilities.

Cpu: Ryzen 2700 @ 4.0Ghz | Motherboard: Hero VI x370 | Gpu: EVGA RTX 2080 | Cooler: Custom Water loop | Ram: 16GB Trident Z 3000MHz

PSU: RM650x + Braided cables | Case:  painted Corsair c70 | Monitor: MSI 1440p 144hz VA | Drives: 500GB 850 Evo (OS)

Laptop: 2014 Razer blade 14" Desktop: http://imgur.com/AQZh2sj , http://imgur.com/ukAXerd
