stutters in games on new Ryzen 7 9800X3D / RTX 5070 Ti build

Hey everyone,

I just built a new PC with the following specs:
• Ryzen 7 9800X3D
• RTX 5070 Ti
• Gigabyte X870 Gaming X motherboard
• 32GB 6000MHz RAM (EXPO enabled)

I installed the CPU and motherboard drivers through Gigabyte GCC, and the GPU drivers from NVIDIA.

The issue: in several games (Apex Legends, League of Legends, and probably Valorant), I’m getting stutters while playing. No major FPS drops, just small freezes that make the gameplay feel choppy.

Interestingly, I don’t notice the issue in BF6 Red Sec.

I also installed SignalRGB and HWiNFO64, nothing else besides that.

Has anyone run into similar issues? Any ideas what could cause this?
– BIOS settings to check?
– Should I avoid GCC-installed drivers?
– Possible conflict with SignalRGB or others ?
– Known issue with the 9800X3D?

Any suggestions are appreciated!
