Just noticed that there’s something odd happening with the resolution of the demo - I had to set it to a higher resolution then back to full HD in the console before it was actually the right res. As a result it wa running even slower than I realised, so I added some level of detail controls to the effect. Back to running nice again. I’ll upload a new version soon, but this makes me think I’ll do my best to get this running good on HMD before submitting it, since that’s the entire point of it.
