DLSS and FSR both have blur, the only option in-game is to make it 99 render scale with FSR but then it creates way too much sharpness. Give us the option to not use either, and before people say "but FSR with 100% means it's not enabled" this is not true, FSR still for some reason has blur, when it shouldn't at 100%.
The only viable option right now if you're using Nvidia is to enable DLSS, then add Game Filter through Nvidia Experience (ALT+f3) and use the Sharpen filter, set this to 20%. Don't use Sharpen+ this is an FPS hog.
