**System:**
- Distro: Nobara 44 (kernel: 7.2.10-200)
- Desktop: KDE Plasma (Wayland)
- CPU: Ryzen 7 5800X3D
- GPU: XFX RX 9070 XT (Mesa / RADV)
- RAM: 32 GB DDR4
- Monitor: 3440x1440 @ 144 Hz
- Mesa / Vulkan: Mesa 26.2.5 (latest stable)
- Game installed on a 2TB NVMe (secondary drive, btrfs)
**Game:**
- Control Resonant
- Proton: GE 11-9 (latest)
- Resolution & settings: 3440x1440, FSR Balanced, Ultra, RT Medium
- Launch options: `PROTON_ENABLE_WAYLAND=1 MANGOHUD=1 gamemoderun %command%`
**Problem:**
I'm getting heavy stuttering when moving the camera in outdoor areas. This doesn't happen indoors. The GPU stays at 99% utilization the entire time (CPU bottleneck ruled out), but power draw drops significantly when I move the camera from my max TDP of 270W down to 210W or lower during the stuttering. The issue completely disappears when I stop moving the character.
I tested the game on Windows (dual boot) and it runs perfectly smooth.
**What I’ve already tried:**
- Different Proton versions (Proton Wayland, CachyOS, Experimental, and older GE versions)
- Gamemode
- Full system/kernel/driver updates
- Disabling any undervolt or TDP limits
- Disabling VRR
- Lowering graphics settings, disabling RT and FSR
- I’ve read about a kernel parameter workaround that can slightly improve performance, but it affects all games and I don’t feel comfortable applying it just for this one
In the video you can see the issue described above.
Thanks in advance 😆
