When any Nvidia driver version newer than 572.70 is installed, the screen freezes and as soon any game is started and the GPU enables the mux switch to switch to the discrete GPU or when i use the discrete GPU only mode. 572.70 and any newer version doesn't show this problem and i can play without problems or use the mux switch. I reinstalled windows 11 with a thumb drive, installed the newest iGPU driver or the one provided on the driver page of the laptop, ofc also have the newest bios installed and am still facing the same problem. The laptop works fine on v572.70 and earlier so it's not a hardware issue but i'm out of ideas how i can get it solved since some newer games start to require the newest driver

    Hi Satefan,
    MUX Switching Freezes on Triton PT515-52s – Known Driver Conflict This is a known issue affecting RTX 3080 Ti variants of the PT515-52s. When using NVIDIA drivers newer than v572.70, screen freezes can occur during MUX switching — either when launching games or forcing dGPU-only mode.

    What’s confirmed to work:

    • Roll back to driver version 572.70 or earlier.
    • Use DDU (Display Driver Uninstaller) in Safe Mode to clean out all NVIDIA drivers before reinstalling.

    👀 Note: BIOS v1.26 (dated 2025/04/17) doesn’t resolve the issue, and Acer hasn’t released any firmware-level fixes related to MUX handling or VRAM address conflicts.

    📦 If newer games demand updated drivers:

    Since you mentioned this is a known issue, is this issue actively tracked by the engineering team? Also you mentioned Bios Version v1.26 but i can only find v1.08 on the driver page. Where do i find a more recent one?
