To be honest, reading the steps myself doesn’t even ring any bells for me. I could’ve sworn it had something to do with ‘3D settings’ in the Nvidia Control Panel, but hey, idk?
I don’t think the steps are different, open the NVIDIA Control Panel (which can be searched or opened by right-clicking the desktop and clicking "Show More Options) then go to Manage 3D Settings, and select FiveM from the drop-down list and choosing high-performance NVIDIA processor.
