Civilization 5 is lagging after starting the game

1. First of all, check if you are prioritizing the use of discrete graphics cards, if the computer is set to use integrated graphics when you start the game, then lagging is normal.

2. Secondly, if you are sure that you want to use a discrete graphics card, check whether the graphics card driver needs to be upgraded, and whether the driver is up to date

3. If you need to upgrade, please upgrade the graphics card driver according to the requirements, and pay attention to make a good backup of the original driver before upgrading.

4. Before entering the game, make sure to close all other programs and processes. Programs and processes outside of the game will eat memory, graphics card and other resources.

5. Make sure your computer has the latest version of DirectX installed
