Sure, well it's certainly raising it's profile and raising its ugly head through dark moody settings such as ED, Chronos, EVE Valkyrie.. there are no doubt many not initially noticing it should they not be playing in games with a dark setting, but it's definitely being reported quite a bit. Red tint issues on the right screen, contrast/posterisation issues weirdly turning up in the left screen mostly, banding issues, crushed blacks etc etc.
Oculus have a 'spud' tool that tweaks certain settings to then monitor and give them feedback to these issues and apparently they think they may be able to fix via a software patch, but for now my unit is 50/50 good/bad for games such as Elite, Project Cars in the darker/dusk settings, ETS2, Eve Valkyrie.. it's subtle but enough to make you feel boss-eyed when viewing. Check the Oculus support forum or search for 'red tint' or 'spud tool' or any of the above problems to find that their QC seems off at the moment.
It's annoying as i, like many others, waited many many weeks for my unit and i do really like the Rift, god-rays and all.
Oh, one more thing i forgot to say... Elite in the CV1 has a much much better sense of scale than the Vive. Something is not quite right with the Vive incarnation yet.. which is a shame, as i'm sure many Vive owners are enjoying ED, but CV1 makes you go 'wow' at the sheer scale of stuff..
