Having all the exact same issues as you. 4070 Ti, HP Reverb G2. Also running without Steam VR but unable to utilize any upscaler without the distortion you've described. When I try running it through Steam VR the game turns into a slide show. Hoping they can fix this one so we can use upscalers.
Thank you, at least i know its not specific to me, am sure they will fix it (fingers crossed!).
I read on another post that when you select the upscaler disabling dynamic resolution might fix it - havent tried that yet but will do and report back.
