Update Your Drivers

Project Zomboid is released in a good condition. If you meet the minimum requirements of the game, it’s likely that your outdated graphics driver is the main reason why Project Zomboid is crashing. We highly recommend getting the latest update for your PC. You can visit your hardware manufacturer’s official website to get the latest update for your device.

Manually downloading and installing drivers for your PC is time-consuming. For some, updating drivers may be a little bit complicated. For those who want an easier method, we recommend trying IObit’s Driver Booster to automatically download and fetch the latest and needed driver update for your PC. In our case, we used Driver Booster to update and fix the crashing and performance issues in Project Zomboid.
