Render distance on W10 locked to max 16

I don't know when exactly this happened so it might have starter on an earlier build, but I can no longer set higher render distances than 16 chunks (gfx_viewdistance:256). If I do (by editing options.txt) it will only render up to 16.

I am very used to playing with 32 chunks (gfx_viewdistance:512), and the increased distance and performance has always been the one reason I moved from MCPC, but it seems to be clamped to 16 now?

I read that on mobile it was reduced to 6 which should be ridiculously close, there are a lot of reports of that, but I found none about the PC version also being clamped to 16. Please release this ASAP, it is the most redeeming quality of MCPE on PC over MCPC
