If the phenomenon occurs even though your PC meets the required operating environment, please try the following.
* When you change settings and update drivers for hardware and peripherals, please do so at your own responsibility.
1. Verify Integrity of Game Files on Steam
From Steam [Library], click the gear icon, and select [Properties] > [Local Files] > [Verify integrity of game files].
2. In an environment with multiple GPUs (e.g., an environment using both a CPU-integrated GPU and a video card, or an environment using multiple video cards), change the graphics settings of your display
The following steps may allow you to use a GPU with higher performance, and may improve the phenomenon.
- Right-click on the desktop, and select [Display Settings] from the menu.
- Select [Graphic Settings] at the bottom right of the dialog box.
- Set [Choose an app to set performance] to [Classic App].
- Click [Browse] button.
- Select the game startup file (executable file) in the location where the game is installed, and click the [Add] button.
- Select the added game icon and click [Options].
- Select [High Performance] and click [Save].
3. Change the startup environment settings
For game titles that allow you to adjust the startup environment settings in [Startup Environment Settings] or [Settings] section on the game launch screen, change each item to a lower setting.
This may reduce the load on your PC.
4. Update or rollback (or reinstall) the video card driver
Go to your hardware manufacturer's website to download and install the latest driver for your PC's video card. Please also update your sound card driver.
* There may be newer versions available on the websites of your board or chip manufacturers.
* Please rollback or re-install the drivers as well.
* The latest driver for your chip will be available from the following sites of each manufacturer.
5. Reduce the number of resident applications (software) as much as possible and start the game
* Resident applications are software programs that are classified as "background processes" in Task Manager.
Make sure there are no applications running in the background, such as Windows Update or security software updates.
6. Temporarily deactivate running security software, or set this game as "exception (exclusion)" in the security software, and then start the game
* The operating procedure of "exception settings" differs depending on security software. For details on how to operate it, please contact the manufacturer or retailer of the security software you are using.
