why setx GPU_FORCE_64BIT_PTR 0
and not
setx GPU_FORCE_64BIT_PTR 1
?
This algo doesn't require huge amount of memory. Setting GPU_FORCE_64BIT_PTR to 1 could potentially hurt performance since memory access would require twice the number of clock cycles.
I also believe it is redundant to set this to 1 with reasonably new drivers.
I'm using GPU_FORCE_64BIT_PTR=0 for at least half a year and am yet to find a miner/algo that didn't work with that on RX480 in windows 10 (and I believe I have tried almost every miner/algo for AMD available)
