FencesMenu64.dll Conflict with Riot Vanguard and VALORANT
Windows Version Number: Windows 10 22H2 (OS Build 19045.7807)
App Version: 3.1.8.5
I've been using Fences 3 for several years without any issues, but recently I've encountered a problem when playing VALORANT.
Whenever Fences is running, VALORANT experiences significant FPS drops and stuttering whenever I move my mouse. Interestingly, when I stop moving my mouse, the FPS returns to normal.
I also started receiving notifications from Riot Vanguard stating that FencesMenu64.dll is interfering with the Riot Client.
I've done some troubleshooting to confirm whether Fences is responsible:
-
Disabled Fences from starting up with Windows and restarted my PC. VALORANT then ran normally without any stuttering or FPS drops.
-
Re-enabled Fences, and the same performance issue returned.
-
Confirmed that Vanguard specifically identifies
FencesMenu64.dllas the interfering file.

System/Software Information:
-
Fences Version: 3.1.8.5
-
Affected Application: VALORANT
-
Flagged DLL:
FencesMenu64.dll
What's confusing is that this issue never occurred before, despite having used Fences 3 for several years. It only started happening recently, so I'm wondering if this could be related to a recent compatibility issue with Riot Vanguard.
