I have an MSI GP72 6QE Leopard Pro which works extremely well in itself only in games, the gaming laptop has a problem. At the beginning of the game I have depending on the game on average 130-140 fps but after 5 min about the Fps drops to around the 60th request for help.
This is not a gaming notebook. And probably your 2 GB RAM of the VGA are so full that nothing works.
With the GTx 950m you are on the level of a desktop GT 1030 or RX550. Not much happens.
Probably you try then also FullHD😂
