VALORANT EXPERIMENTAL SHARPENING Explained 

UPDATE: NVIDIA has removed the Sharpness setting in NVIDIA Control Panel. You can re-enable it back by modifying:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
vlddmkm\FTS
EnableGR535= 0x00000000 (0)
You can of course still turn up Sharpness using the monitor hardware buttons on your monitor.
UPDATE: As of Patch 1.11
Setting has been renamed to (Beta) Experimental Sharpening and it's effect has been slightly reduced (equivalent to 0.5 on Nvidia Sharpening setting). Also Riot has decided NOT to remove the setting and keep it available for you as they continue to test it.
NOTE: You MUST restart Valorant for NVIDIA Control Panel settings to take effect!
NOTE: Most "Gaming Monitors" should be able to able to handle Sharpness without introducing noticeable ghosting.
What does the new setting Experimental Sharpening in Valorant do?
It makes textures and edges sharper, more crisp, and more vibrant. Effectively making visuals in the game "pop" more and yes that does mean enemy agents "pop" more as well.
The technical explanation of Sharpening is this:
If we take numbers to represent the shade of grey with 0 being white and 10 being black and we represent a series of pixels as 3-3-3-7-7-7-3-3-3. If we were to increase the Sharpness on this row of pixels the resulting numbers would be 3-3-2-7-8-7-2-3-3 effectively increase the range of color/shade as well as increasing the abruptness in color/shade changes between pixels.
