It can be used to easily resolve the problem triggered when the CPU overclocking option available from the in-app menu is set to a value larger than x1.
This is probably the best-known method for resolving this problem and it’s suggested in numerous forum posts and videos across the Internet. Sometimes the problem is caused by outdated drivers but more often it’s the case of the newly installed driver which don’t fully support the program. It’s weird that the program would automatically set this option to something other than x1 but it causes ePSXe to crash and it should be changed.
