As a photographer, we can definitely feel how this can be impacting to your works. We suggest the methods below to troubleshoot:
- Run the Surface Diagnostic Toolkit and check for Windows update.
- Check the power mode slider. Go to the battery icon > Slide to Best performance and observe if the issue still persists. Setting the Power mode higher than Recommended will impact battery life, remember to lower the slider when no longer need the CPU performance boost when on battery.
- Check GPU performance. Go to search bar > Search for Task manager > Go to performance tab > Check on how the GPU behaves.
- Set GPU as graphics processor. Go to search box > Open Nvidia Control Panel > Go to Manager 3D settings > Under Global settings > Choose "High-performance NVIDIA processor" as the graphics.
- Download and install the driver's package. Check the specific OS build of your Windows Settings> System> About.
