Question about Microsoft Flight Simulator Premium Deluxe

You can, but only on the lowest settings. Don't expect a smooth gaming experience though

No, that's not possible, everything is too weak.

Hello
System requirements. Microsoft Flight Simulator runs from Windows version 10 with version 18362.0 or higher. This requires a quad-core processor at the minimum performance level of an AMD Ryzen 3 1200 or Intel Core i5-4460 and a graphics card from Radeon RX 570 or GeForce GTX 770.
Conclusion: Your laptop is not suitable for the MS FS 2020. The FS 2024 is expected to go on sale this year. It will have even higher system requirements. However, the minimum requirements mentioned above are not recommended. My system:
Omen 30L Desktop Intel Core i9-10900CPU, 3.70GHz,RAM 32.0GB and a GeForce RTX 8090 graphics card.
I hope I have helped you. Greetings and hopefully a good flight.
Greetings Georges

I would not recommend

I can't say I had to buy a new graphics card from nvidia geforce RTX 3060 which definitely works costs 400.00 euros

Unfortunately, I can't answer that. I have no idea.
