A few days ago, I started experiencing low FPS in all my games suddenly. These days, I play CS:GO mostly, but I checked other games and they too suddenly gave me lower FPS than before. I used MSI Afterburner to monitor my GPU usage, and it showed GPU1 being used while GPU2 remaining at 0%. I tried making all the games run on the dedicated GPU (which I assume is GPU2) through the control panel, adjusting global settings within the panel, rolling back to the last drivers I knew were working properly, none worked (that last one may have made things worse, actually)



My laptop has switchable graphics, with Nvidia GT740m as the dedicated GPU



Any help would be greatly appreciated

Go to nvidia control panel ( by right click or through start) you will see an option about what to use select there use high performance nvidia clocks there will be other settings like don't use nvidia clocks or auto adjust which will drop frames by letting us integrated GPU work .
Imp note : This drains a lot of battery as nvidia GPU is used continuously and may heat also so just do it before playing games otherwise keep it to auto adjust for power saving and efficient tasks. I damaged my battery in 2 and half yrs by keeping it continuously (nvidia) on.

Check the BIOS whether there is an option to switch the GPU to dedicated.

The global setting is already set to High Performance

The bios only has settings for integrated only and switchable. Mine is set to switchable
