Question / Help NVENC Hi44p profile causing video oddities

So I recently updated OBS studio to 0.14.1 and saw that we've got the actual NVENC encoder in this; it was only natural I try to stick it on what I believed to be the absolute highest settings as below

Bitrate: 90000kbps (because I can (and it wont let me go higher))
Keyframe Interval = 0
Preset = High Quality
Profile = high444p
Level = auto (have tried 5.1)
Use Two-Pass Encoding: no
Use CBR: no

Output Resolution: 1920x1080
Color Format: RGB
YUV Color Space: 709
YUV Color Range: Partial (full seems to make everything much more darker than it needs to be)

So, after recording a short 30 second vid I go to preview it and WMP decides that no, it cannot view this video (black screen is all I get) and VLC shows.. interesting results: the majority of the video is, well, green. Since VLC lags and has a bunch of issues for reasons I just never found out, I dumped it into Premiere Pro and verified that, yes, VLC wasn't just being itself.

This is pretty much what it ends up looking like, the 'ghost images' all displaying different frames as well. Trying this with the i444 color space produces a similar result but the 'ghost images' don't really exist. Video dimensions end up being 32x7680 for whatever reason

Basically, what I'd like to know is if this is just me being stupid or if it's the encoder/OBS/something else being stupid
 
I can confirm this

the high444 profile is only useful for lossless encoding, which is not yet impemented in 14.1
hope it comes with ne next release :)

use main or high instead.

I just realized that I'm missing a 4 in the title.. oh well

Ech, figured.. Ah well, ended up using x264 with CRF set to 0 to more-or-less get what I needed anyways
