On an SSD pop in is non existent, playing on Pro. And loading times are less than 10 seconds long.
I've asked Tom to test the game using SSD, but I doubtt hat he will see it.
Performsnce is worse (much worse I think), but graphics are awesome. Zero pop in.
Yesterday I tried to go to all the places with lots of geometry trying to crash the game: Japantown, Kabuki, City Center ...
And yeah, framerate got worse with time. The game still has SERIOUS memory leak problems.
Its not flushing memory in time, so the game tanks after a while. But at least I havent found a crash so far after patch 1.2.
