GTA V on Dell 7560 i7 with 940MX [duplicate]

1. Graphics Memory: 4 GB
2. Graphic Processor: NVIDIA GeForce GTX 940MX
3. Processor: Intel Core i7-7500U (7th Gen)
4. Game is loading from HDD

I have fairly recently bought the Dell 7560 with the aforementioned specifications. I have bought an original copy of GTA V. And I have installed and kept updated the GeForce Game Ready Driver.

However, I am facing a lot of lag and a very bad experience while playing the game even with minimum settings. This is just frustrating. Just loading the game fires up the fans as if I am launching Falcon Heavy.

The game is installed on my hard drive.

My question is, are there any software which I should install to optimise my gaming experience?

How do I enhance my gaming experience? Any tips? Thanks
