- We also struggled initially, particularly with large alpha objects that result in a lot of overdraw (which frustratingly you can't preview in-editor with LWRP :/ int 2018 LTS). The short answer is, try to minimize it. This thread on the unity forums has some discussion about quest performance:

And this blog post discusses the GPU architecture briefly and why large alpha objects are a bad idea (it's for Gear VR, but the reason holds):
