Sorry, I'm confused. People are reporting differing results. What would need to be made persistant? 160? That's easily accomplished. But what else does changing this break?
Dalingrin was going to make 160 the default when the new market originally came out, but it seems that eventually having the dpi at 160 will break the market...
I refer you to this discussion
