Valve closed bug report thread on github while issue still persists in latest “stable” steamos 3.5.7.

From the thread on github with bug report you can see two things:

  1. Bug exists since 3.5.1 preview

  2. Valve denying this is a bug. Instead they tell people that it’s only affecting gpu clock display in performance overlay and try to convince people that it’s not affecting performance.

I don’t know why they do this but you can easily check that Valve is not telling truth and this is in fact affect performance in many games. You can confirm this either by locking gpu to 1600 mhz or by rolling back to 3.4 steam os where bug is not present.

This behavior rising concerns, because 3.5 Steam OS is far from “stable” if you compare it to 3.4. Issue affects both LCD and OLED steam decks.
It would be nice to get coverage and noise from channels like Gamers Nexus but as of now I don’t see that any major youtube tech channels picked up this issue.

    I’m getting it on the OLED model in Cyberpunk 2077, The Surge 2, and TOTK in yuzu. Performance has been hit quite badly with tons of microstutters.

    I ran Cyberpunk side by side LCD Vs OLED, exact same SteamOS build, exact same graphics settings in both, (game video, game graphics, deck QAM) and on the OLED where I have this issue the frame times are all over the place and it is visibly stuttering whereas on the LCD deck it is a locked smooth consistent 30fps

    The clock speed flickers rapidly to 200mhz and back up and now and then also gets locked at 1040mhz whereas on the LCD it adjusts the GPU clock speed in a more normal manner.

      Please, record a video of the exact test you described and just send it to Valve.

        I have already recorded a video and intend to do that as part of an RMA process.

        “Just send it to valve”. So I can’t post my experience of this in a thread literally discussing this issue?

      Yeah same here. LCD is basically stutter free on cyberpunk2077, OLED drops sometimes into the teens. Makes no sense. Please update me if getting a new deck fixes it for you!
