@DaxInside - Aye, the aliasing issue is perplexing me somewhat. Like I said, running at a lower than 'native' res and then upscaling usually results in a softness of image, and if anything can actually alleviate jaggies/aliasing. It really is a learning curve getting to grips with VR and its foibles.
I have to say I'm glad I got the G2 as it's basically the highest resolution headset out there for reasonable money. I dread to think what much lower res headsets look like.
In terms of Flight sim 2020 settings, I found a lot of good info on here

The main thing I'm playing with (and that has the biggest impact on performance and clarity of visuals) is obviously the resolution scale slider ratio between OpenXR and in game. This quick table below from the link above is a good starting point. Obviously 100% in both is what you want, but it's just not possible for me it seems. Even with a 3090FE which is what I'm running. I do have an fairly ageing CPU though (i7 5930K) but it's overclocked high at 4.5Ghz, and when gaming at 4k or super high resolutions like the G2, then usually you're entirely GPU bound. However, Flight Sim is a strange beast and CPU definitely plays a big part. I'm trying to convince myself I don't need to update yet as Asobo might bring out more performance fixes, and DX12 which will help a lot. I also can't justify updating my whole CPU, motherboard and Ram for one game, as everything else flies with the 3090 and my 5930k at 4.5Ghz (non VR games anyway!)
(I'm currently favouring OpenXR 100%, 60% in game as mentioned earlier...)
FS2020 OpenXR Comments
TAA 70% SS 70% Well balanced gauges and external visuals with solid fps
TAA 80% SS 60% Best for Airliners where EFIS sharpness is more important than external view
TAA 60% SS 100% Best for analog gauges GA aircraft with super detailed outside view.
The other KEY thing to experiment with if you want ultra smooth judder free flight in Flight Sim 2020 is the Motion Reprojection. In OpenXR you have to set this to Automatic (or always on) if you want frame interpolation ('motion smoothing') on. I think it's also best if you toggle the "Use latest preview OpenXR runtime" to on when using Motion Reprojection. For this to work effectively you HAVE to make sure that you are hitting above 30fps at all times. This then gets interpolated up to 90. If framerate drops under 30 by any tiny amount - you get horrible judder.
A good way to check all is good actually in game regarding the above is to tick the "Display frame timing overlay" box in Open XR. This makes a floating box with stats appear in your field of view - the key numbers to look out for are 30Hz on the first line and 90Hz on the second or third (can't recall). If the box stays blue all the time it is smoooooth as silk. If the box is red you are not hitting the right targets and you'll have terrible judder. If the box flicks between blue and red you are not hitting it consistently.
The negative of Motion Reprojection/ smoothing though is just the same as on TV's. You can get strange artefacting of the image at certain times. Quickly panning around the aircraft in external view is pretty bad, but aside from that I've found very few other issues so far.
P.S. What FOV mod is it you mention? I got the VRcover gasket which is slightly different curvature and has a thinner pad. Using that has definitely improved things a bit for me.
