Xbox ROG Ally X: High FPS (60-100) but feels like 30 FPS after ~1 hour of gameplay
Hi everyone,
I recently got the Xbox ROG Ally X and I’m running into a strange issue. When I start playing (specifically Uncharted 4), everything starts buttery smooth. However, after about one hour of gameplay, the game starts to look very "choppy" or "stuttery."
The weird part: My FPS counter still shows 60 to 100 FPS, but visually it looks and feels like it’s running at 30 FPS or even lower. It's like the display refresh rate or the frame pacing is breaking down on my Xbox handheld.
What I’ve checked so far:
• Device: Xbox ROG Ally X (24GB RAM model)
• Settings: Turbo Mode, 120Hz display, VRR enabled.
• Troubleshooting: I disabled AMD Vari-Bright and turned off Frame Generation (AFMF) in the Xbox/AMD settings, but it didn't solve the issue.
• Heat: It seems to happen only after the device has been running for a while.
Is this a known VRAM issue with Uncharted 4 on the Xbox Ally X, or could it be thermal throttling of the RAM/VRMs? Even restarting the game doesn't fix it immediately; only a full reboot or letting it cool down seems to help.
Has anyone else experienced this "high FPS but looks like 30 FPS" bug on the Xbox Ally X?
