The sims 4, půjde mi to na vysoké kvality bez sekání?

Teoreticky ano.

The Sims 4 Laptop Mode
The Sims 4 is automatically set to run at ideal rendering quality. However, we know that some of our players may have older computers, or prefer to play on laptops, which may have lower power graphics hardware. Laptop Mode will put the game into a reduced rendering mode designed to run the game more efficiently for better frame rate and battery life.

To turn on/off Laptop Mode:

Click the “…” icon in-game.
Click “Game Options”
Check or uncheck the option for Laptop Mode
