Can confirm this issue is on vega as well.
Block 3M = 34 MH
Block 4M = 29 MH
Block 5M = 22 MH
Funny will be amd releasing the fix for vega cards miners and leave polaris owners on dark, i wonder what kind explanation amd will give but I think amd already fixed vega gaming drivers before launch, so amd can say veqa dos not suffer the same as polaris but in reality it does and amd did not want to fix polaris hehe
This is a driver issue. AMD can fix it.
We will see, I just now read by claymore that claymore miner doesnt even recognize vega, (Edit: As you can see post above.) so maybe he is getting false results. (he tested 3M and 4M block and there is difference, but problem is starting after 4M block) in reality vega and polaris are build on a different architecture so vega should not have the same problem, but you never know. Why do you think that amd will fix only vega but not polaris? For profit?
Btw i don't think its driver issue, because other amd cards works just as normal.
