Thanks for the reply.
DLSS with higher resolution scaling does appear to help a little to reduce sharpening so I think I'll do something similar for now. You can offset the performance hit by using a lower mode, but it does have a higher vram cost and it's still oversharpened enough to appear visually noisy to me, so I'll still hope for a slider.
Also if you have a NVIDIA card you can press alt+f3 and choose the sharpening option to do it that way while also using DLSS. (I don't see them adding a sharpening option but never say never).
Yes the Sharpen+ filter has a texture detail option than can scale negatively and help decrease the sharpness. These filters also come with their own performance cost though and I'd rather it was all in game, so it's not fully ideal, but still it's a nice option to have true.
