Hello,


I have a strange performance issue with S&box.
 The main menu freezes every second, but once I go in-game or open another page (like servers) the freezes disappear and the game runs normally.


This makes the main menu almost unusable.


My PC specs:


  • GPU: AMD RX 6700 XT (12GB)


  • CPU: Ryzen 5 3500X (6 cores)


  • RAM: 32GB DDR4


  • Storage: SATA SSD


  • OS: Windows 10


What happens:


  • When I start S&box and stay on the main menu, I get a micro-freeze every second.


  • When I open another menu page (like Servers / Games Hub) the freezes stop.


  • When I join a game, the game runs normally without freezes.


So the problem seems only related to the main menu UI/rendering.


Things I already tried:


  • Disabled AMD Fluid Motion Frames 2.1


  • Disabled Radeon Anti-Lag


  • Disabled other AMD driver features


  • Updated GPU drivers


  • Restarted the game multiple times


Disabling AMD features reduced the problem slightly, but the freezes are still happening.


It feels like something in the main menu rendering (maybe blur, UI animation, or background rendering) is causing a periodic stutter.


Has anyone else experienced this issue with AMD GPUs, especially RX 6000 series?


Any help would be appreciated.
