1. Like others have mentioned, this “sweet spot” thing I can see being a real problem. I’d say only about 15-20% of the whole view is in focus in the centre. If I just move my eyes to look around then it’s blurry and so obviously not as crisp and beautiful, it’s very very distracting.
does the Quest 2 have this issue? Does the index? If not I reckon I might prefer consistent clarity across the whole image, even if the resolution is lower
Firstly make sure you are setting your IPD correctly, but yeah I'd say for me maybe the centre 30% is really crisp in a sort of oval shape (falls off more rapidly vertically than horizontally). You get used to moving your head to look rather than your eyes, and once immersed in a game it often becomes a non issue.
Quest 2 is probably a little better, but that's partly because it isn't quite as clear in the centre to begin with... the G2 gives a bigger contrast because of just how good that sweet spot is. Index has the best uniformity (even more impressive when you consider it has more FoV than the others too) when it comes to clarity due to the dual element lenses but those come with other drawbacks like increased glare in certain scenes and obviously it can't compete in pure resolution terms.
I’ve read about making sure it’s All aligned properly, and that maybe getting a modded gasket will help to get eyes nearer the lenses. Is this worth it? Any Significant difference?
I have my doubts though. Is this just how it is? Not sure I can live with that as it’s so jarringly obvious, as the sweet spot area is so damn incredible.
Vertical alignment also important, as is playing with the tilt. Make sure the strap is cupping the bottom of your head. We all have different shaped faces so it will vary but try tilting the headset slightly up or down as well. Facial interface one is real easy to test - just remove the stock facial interface and hold the headset as close as you can to your eyes - this will give you a good idea of what (if anything) you will gain from a shallower interface. Again, give it some time and play some actual games and you'll probably get used to the sweet spot fairly quickly.
2. I have absolutely no idea what I’m doing with regards to using either Windows own vr settings, steams own vr settings, something called openXR vr settings, or a combination of all three. Can anyone link me to some definitive info please on what to use for what games and why?
For WMR generally just make sure you have best quality selected, I also turn off the automatic control switching. SteamVR will be screwing with you on your 3090 and trying to set around 130% as a base resolution. Manually set that to 100% and then you can tweak further per game as required...
OpenXR only applies currently to MSFS and Minecraft bedrock. It is the future of VR though so expect to see more of it over the next couple of years... Put really simply it is like a universal standard that allows games to run on any platform without needing to go through any other compatibility layers or requiring any runtime specific implementations. you can download the OpenXR developer app from the windows store which will allow you to change resolution like steam, force/turn off motion smoothing etc. It will only have any effect on OpenXR games.
