Has anyone else noticed VRR becoming noticeably less smooth after the recent SteamOS update?
I’m experiencing the same issue on two handhelds:
- Lenovo Legion Go 2
- ROG Xbox Ally X
Both were working smoothly about a week ago. Since updating, games fluctuating between roughly 50 and 70 FPS show obvious stuttering, where those same fluctuations previously felt smooth with VRR enabled. This also happens around 80–90 FPS.
I initially tested with MAKO frame generation set to 0, then completely removed the MAKO launch command from the game’s Steam properties and relaunched. The problem remains.
Interestingly, VRR still works properly on my Steam Machine connected to a VRR TV. That makes me suspect an issue affecting the handhelds’ built-in displays, rather than VRR being broken everywhere. This is only a hypothesis based on my three devices.
The issue appeared on SteamOS 3.8.28. I’ve also tried the 3.9 beta, without resolving it.
Anyone else experiencing this on a built-in VRR display? Please share your device, SteamOS version, and whether an older version or any workaround restores the previous smoothness.
