DEVICE : Legion Go S Steam OS Variant Z1 Extreme 2025.
Updated from stable 3.8.16 to 3.28.28
Further,
Like a pandora box this update has been.
Terrible Frame Times for games , 16.7 ms frametime but never 16.6 ms ,
Most games are stuttering terrible you can feel it ..
My device has gone from amazing to absolutely shite after update
Even My Home Screen feels stuttery, especially on low power while it was flawless before.
VRR doesn't seem to be working in some games screen just jerks sometimes.
Updated to 3.9.2 beta something after a lot of research and it's just getting worse by each update I have never experienced any issues ever but after this 3.8.28 update suddenly it feels like something in background is stuck.
What I have tried till date since sept 25 2026
Updated to 3.8.28 stable issue start 25 sept 2026
Factory reset at 3.8.28
Changed UMA buffer never even touched it since buying device new in May 2026 changed UMA buffer to 8gb from Auto.
Nothing worked to fix the problems still inconsistent frame time tested games no fix.
Went back to 3.8.28 stable factory reset after update.
No fix issues still persist terrible microstutter making games feel stuttery
Went back to 3.9.2 beta and have updated everyday everything available hoping something magical to take it back to previous days.
most recent update I think something released on 11th October on beta channel.
As of today 13th October my device has fallen to a new low with stuttering on. Home Menu on Low Power as well as balanced mode.
How did things go from masterclass to such a huge pile of shut!
I am truly troubled as if I made the biggest most of my life updating in 25 Sept 2026. I have no clue what to do anymore and dying inside day by day.
PLEASE HELP IS THERE ANY SOLUTION ?
