GPU memory and dual mining

[hcwh]

Is there any definitive evidence of a correlation between GPU memory and dual mining performance? In other words, is dual mining significantly more effective for 8GB cards compared to 4GB dual mining?

Memory size does affect dual mining performance if there is innsufficient VRAM after the Dag. With the current Dag size, only 3 GB cards have signinficantly lower hash when dual mining. I have RX 580/480 8 GB cards and also RX 570 4 GB cards and the performance difference on dual mining with DCR is less than 3% between the two.
