Those using the Nvidia game filter to play Valorant are going to run into some troubles in trying to fix an error with GeForce Experience, as there is currently no fix due to a game-breaking bug when using the "Remove HUD" filter.
Players that use are using the Nvidia Freestyle feature through GeForce Experience have allowed those to have more customization than what the game allows users to have on the screen. Filters can be retroactively applied to the game to enhance contrast and colors just through an in-game overlay.
However, the feature may be a bit too powerful as the filter is now disabled by Riot Games due to a game-breaking bug that is happening, as players were able to not get flashed even if looking directly into it.
NVIDIA Game Filter Not Working in Valorant: How to Fix
A user on Twitter found that when the "Remove HUD" filter was on, it completely removed any on-screen flash which is a significant advantage for players and compromises the competitive integrity of the game.
Since then, Riot Games seems to have disabled the use of the Nvidia filters and is listed by the Nvidia software as not being a supported game when using trying to use the GeForce Experience overlay.
So, for players looking to fix the Nvidia filter for Valorant, it may take a while before Riot Games and Nvidia manage to collaborate in order to implement a sort of fix due to the game-breaking nature of the bug.
