A Supported Game is Required to Use This Feature Valorant: How to Fix
The crux of the issue is related to NVIDA, more specifically how certain NVIDIA drivers prevented flashes from working properly in Valorant. So, it makes sense that most of the solutions involve going into your NVIDIA settings. The first thing to try is updating your drivers for NVIDIA. If updating the drivers doesn't resolve it, try uninstalling and reinstalling. Both of these are something simple and easy, so it's best to try this first before moving on to other methods.
If that doesn't work, players can head to the GeForce expertise panel, and turn on Experimental Points. It might seem a little strange, but it's worked for other players, so it's worth considering if you keep encountering the issue.
For those who have solved the issue, maybe try snagging the Nice Smile gun buddy using Prime Gaming, and show it off to fellow friends and foes. Or, try checking out the teams for the Twitch Rivals Series 2 in Valorant, featuring a variety of Twitch streamers and talented Valorant players.
