2.8c has all but removed all stales i get reported on screen.
vega 64 impact, no difference in terms of speed mh wise from 2.8b.(ratio of found shares does seem to be lower though when looking at all shares found across all gpus in rig)
fury x the reported hash rates are more level but spikes to higher hashrates are gone. I was getting an avg 35.2 mh on them with spikes to 40.(2.8b) now avg is 34.5 with no spikes. 2.8c
thanks for PM
Update and comparison
2.9d is actually a bit of a loss in hashrate. vega 64 virtually no change from 2.8c. fury x are lower than 2.8c 34.5 avg now
the best speed was 2.8b but stales now are virtually nil.
