Does anyone have better performance on old version of AMD drivers than the latest ones? Or is that a thing of the past?
It is very hard to tell. You might get a faster hashrate displayed but less shares submitted to the pool therefor less effective hashrate. Same with older versions of Claymore Miner. I conducted a serious of experiments but gave up at the end as all that downtime is not be compensated. I stick to the latest versions of everything.
