Of course, that's always an option. It's just that I installed every second or third iterations since 16.7.x for these RX4xx cards and none of them seemed to make any meaningful difference for mining (neither performance, nor stability), except this one. That's why I thought it's worth reporting. And it's always possible that things like this are not driver issues but a software bug exposed by some otherwise neutral changes in the driver, or they are driver bugs but trivial to work around in software...
