Call of Duty Modern Warfare 3 can run at decent framerates on the Nvidia GTX 1650 or GTX 1650 Super with the right settings. But this method will result in noticeably lower graphics. Yet, these GPUs are quite prominent for their price range.
Yes , A GTX 1650 can run almost all types of heavy games. I recently bought a laptop with GTX 1650 and I am already playing GTA V, Valorant ,Rocket league ,PUBG PC and other different games . It runs almost all the games pretty smooth without any lag as per my experience .
