I order a Quest the day that event happened which announced Link functionality, it arrived a few days later and I enjoyed it a lot. Eventually Link beta came out and I enjoyed that too but my performance was always weak, my CPU being just an FX-8350 was having a very hard time with the video encoding, one of the things that chip is worst at doing. 

But I struggled on and I carried on playing VR in headache inducing 15fps for many months. 
Gradually some performance updates for Link did improve things, it got a little more stable, a little higher framerates. 

Today I installed V19 to try out the new Link Performance/Quality setting and I set it to Performance mode. 

It is buttery fucking smooth. What sorcery is this? What absolute fucking witchcraft is this? This has got to be at least a 40fps improvement it is an absolute world of difference, what the fuck?
