- VSYNC is offChief Blur Buster wrote: β26 Jan 2023, 03:27VSYNC tearing is never directly caused by electricity, it's just a cause-and-effect, a domino effect.
- The power management plan configuration settings can change sync settings (driver power management bugs, etc)
- Another common cause is the automatic switch from Intel GPU to NVIDIA/AMD GPU, because many laptops have two GPUs. The different GPUs in the system may have different sync technology behaviors, and the act of GPU switching may not be 100% seamless and may have bugs.
- In some sync technologies, VSYNC OFF may be dynamic. (Like framerates above Hz on VRR, or as an automatic behavior in non-VRR "Adaptive VSYNC"), and battery power can have lower framerates that don't show tearing, while AC power can have higher frame rates that do show tearing because the extra power generated more frames that simply triggered an enable of VSYNC OFF behavior.
- Conversely, sometimes laptop are currently preconfigured by OEM's to switch refresh rates when unplugged, e.g. lower refresh rate when unplugged and when not running a game. The current refresh rate of the screen can influence whether or not tearing appears or not.
- In certain setting screens, laptop software are designed to remember settings when plugged in versus when unplugged, so settings that you configured plugged may not be utilized unplugged, and vice-versa. This can, sometimes, include sync technology setting (VSYNC ON versus VSYNC OFF), even for non-game software too.
- power management plan is same
- only integrated GPU, so nothing changes
- 60 fps locked in game and stable, however need to set FPS counter to confirm
- display locked to 60p in intel graphics center, not auto, all power saving features off
Approach was to exclude any software/hardware settings, however we know that this is impossible, because that is blackbox.
If office electricity will make same tearing maybe you are right, and some changes n laptop settings
