I am also having this problem on both my 65 inch Tcl and my 75 inch tcl. Update 10.0 has made Game mode stutter when on and I dont want to return both tvs. I hope this is something you guys will take seriously.
To reproduce: Plug in any game system (tested with XBox Series X and Nintendo Switch). Select the port it's plugged into and make sure game mode is enabled. You will see a frame blip every 5-10 seconds where it will jump back a few frames then back to where it was.
@RokuDanny-R Would love to know if this is being worked on as well. This is my first Roku product and this is a terrible first impression. I get software bugs, but to effect something as critical as the TVs main functionality. That should be fixed ASAP.
I hope to hear something soon or I’ll be jumping to a brand that does what it’s supposed to do.
Experiencing the same issue. 65S435 running on software version 10.0.0 build 4185-93. Stuttering occurs roughly every 5 seconds while playing PS5 and persists across every game I’ve tried, as well as on the PS5 main menu. I’ve tried troubleshooting by changing various PS5 and TV settings to no avail. Only way to get rid of the stuttering is to turn game mode off on the tv, but having game mode off increases input lag significantly. Didn’t have any problems with stuttering or game mode before the latest update. Hope this helps with getting the issue sorted out!
