SO with no more DAG files needed then how does this effect the hash speed as thing move on as bigger DAG files use to get less speeds use to get. So does this mean should see a improvement in speeds from cards when DAG use be smaller on size n bigger on hashes ?
v4 doesn't change anything about how the DAG is used, just how it is generated and stored. The dagger working set will continue to grow each epoch, and if your GPU slows down more because of tlb issues as the dag grows, it will still do that.
Before, the CPU would calculate the DAG, it was stored on the hard drive, and transferred to the GPU memory over the pci-e bus. Now, only the dag cache is pushed to the GPU, and the DAG is generated on the GPU (and never stored on HDD or in CPU accessed RAM) and only stored in VRAM.
In short, it's a bloody awesome improvement!

@freeapp that sounds right if you're using dcri 100. Dcr mining is a "bonus" in between ethash gpu usage when it's busy with vram accesses. Values between 20 and 40 seem optimal for different GPUs and result in the same or increased ethash performance with moderate decred performance.
