i recently switched up from HP Reverd G2v2 to Pimax Crystal. overall the graphic clarity is really good.
I on the one hand need lens correction too. My experience with 2 brands is different. i know for sure the centre sweet spot is almost near full screen all the clarity is almost across the view. It was the edge that i tend to pick the fight. esp, when you are having the NVG and the instruments, tend to get distorted with one of the bigger brands and make the night flying impossible.
Overall i crank up all the setting to max and on a 4090 it runs at full stream easily to 90FPS those with DLSS i do get some artifacts when performing F3 view when the object is approaching you tends to see artifacts lines bleed off the wing span.
I wonder if any of you have seen this.
Also, i run the OpenXR on Custom resolution upwards of 4320 for the supersampling purpose.
