FC 27 PC – Micro-stutter only in Grounds mode on ROG Xbox Ally X

Platform: PC (Windows 11)

Device: ASUS ROG Xbox Ally X (AMD Ryzen AI Z2 Extreme, 24 GB LPDDR5X)

GPU driver is latest (July 2026)

Game installed on: internal NVMe SSD (~250 GB free)

Display: 1080p, borderless, vsync off

Issue:

While walking around in Grounds mode, I get constant micro-stutters / hitches. Regular clubs or fut matches run smoothly with no problems. FC 26 ran without any stutter on the same device and settings.

What I have tested (none of these removed the stutter):

- Graphics preset Low, all heavy options (hair, crowd, cloth etc.) at minimum

- Resolution 1280x720 with Render Scale 50% (640x360 internal). GPU usage drops to ~55-60% at ~600 MHz, so the GPU is not the bottleneck

- FPS capped at 60, 50 and even 30 (in-game limiter and AMD Radeon Chill each tested separately). The stutter is still there at 30 FPS

- Full 35W power mode with CPU Boost on; temperatures stay under 80°C (no thermal throttling)

- GPU memory allocation set to 6 GB, 8 GB and 10 GB (game uses ~3.5-4.2 GB)

- Fullscreen and borderless

- Hardware-accelerated GPU scheduling on and off

- Performance overlay, sensor monitoring and background recording disabled

- Memory Integrity is off

- Three different internet connections

Observation:

Since the stutter appears only while moving through the Grounds area, and does not change with resolution or frame rate cap, it looks like a CPU-side issue such as asset/world streaming in Grounds. A desktop PC with a Ryzen 5 3600 and RTX 2060 runs Grounds smoothly at medium settings, so this seems specific to power-limited handheld hardware like the ROG Xbox Ally X.

I can provide video recordings with the performance overlay if needed. Please let me know if there are any logs or additional information I can send.

Thank you.
