Is TacoTime right about this? Why are people saying GPU mining will become impossible in august?
Current GPU implementations stop working at Nfactor value due to be in august. IMHO it's unlikely that this can't be fixed. However, GPUs should be much slower by then, only slightly faster than a CPU (AFAIK).
EDIT: see
https://bitcointalk.org/index.php?topic=206577.msg2162620#msg2162620So I am to understand that when coblee asked for suggestions on how to prevent GPUs from taking over litecoin, all he had to do was change the N value to higher than 8192 and litecoin would have become way more GPU resistant?
Coblee's thread about GPU-mining and Litecoin:
