Still having tech pace issues
I've played roughly 3 games on huge maps with 5 opponents and fast pacing. In every game the AI civs have MASSIVELY out speeds me tech wise.
Here is a screenshot from the start of a new game on LH .90

And a similar screenshot from FE 1.32 on a large map

What it feels like to me is that player tech research was slowed down somewhat AND it also suffers from greater unrest ... however it seems as if the AI's tech research was not changed from FE. Over the course of the game it's hugely noticeable. Early on the easiest way to get horses is to visit your neighbors. They get them at least 10-20 turns before you will. Late in the game they have 3 towers built 30-40 turns before I even start to sniff that tech.
