If your laptop has a mux switch (probably in the BIOs) turn it off. Note, this will nuke your battery life as it bypasses the igpu.

Nvidia Optimus is awesome but if you let it auto switch between igpu and dgpu you could be leaving performance on the table due to “Copying over each displayable surface introduces a performance and latency overhead.“
test it both ways

Also with Optimus enabled it’s “Display-specific features available on discrete GPU (like NVIDIA® G-SYNC®, higher refresh rates) may not be available on the laptop display even though the discrete GPU can support them.”
