Are you running the display on your laptop while gaming or are you driving an external monitor with it? Also go into GeForce Experience under global settings and make sure you have PhysX set to use the GPU, and not CPU. Another thing to look into is going into the NVIDIA Control Panel on the desktop and go to Manage 3D Settings and set the preferred graphics processor to high performance NVIDIA processor/
I have a feeling it's a simple setting in your graphics display somewhere. This is assuming you have the Windows performance settings to performance and the laptop is plugged into the wall and not running on battery.
switch V-sync on, and then back off again and see if this helps.
Yeah do that, and what game are you playing? can you make sure there isnt a frame rate limiter?
I played spintires, Counter strike GO, Call of duty world at war, none of which have frame limiters, and all run at 30 fps. I cannot live a 30 fps it is torture.
