A stress test on a PS4 is a process of putting the console through a series of demanding tasks to test its stability and performance under pressure. This can be useful for identifying any potential hardware or software issues that may cause the console to crash or freeze during normal use.
There are a few different ways to perform a stress test on a PS4. One common method is to use a dedicated stress testing tool, such as the PS4 System Stress Test Utility. This tool can be downloaded from the PlayStation Store and will run a series of tests on the console’s CPU, GPU, and memory.
