After my recent “desperation post” on my topic about this nvwgf2umx.dll crash (here: CTD's are back - Nvidia driver? - #43 by Baracus250) I found this topic and I am sure to say it has solved my problem just by turning off Foveated Rendering in OXRTK. Still using DLSS, everything else back to how I had it and it’s glorious again. Thank you for the pointers here folks!! It was driving me crazy.
