A way to make it less blurry

[Major_Tinz]

DLSS is always blurry on my RTX 4090, as the quality mode carves off more than 1,100 pixels away on the long side of my 3440 x 1440 resolution, and no amount of AI can restore that lost quality.

However ... you can get things sharp ... using the RTX Remix Developer Console to set the DLSS render resolution to full resolution, adding frame generation, then also using Lossless Scaling to add interpolated frame generation (adaptive to 120 FPS) and extra sharpening. I also tweaked a number of things in the Developer Console with very minor adjustments, such as tweaking volumetric lighting and also adding dust particles.
