To prepare myself for the long campaigns to come, I've been playing through the Russo Japanese War scenario from both sides, to learn a little more about the specifics of this game.
My first game as Japan went well. I experienced a couple of crashes (game not responding pop up), but it didn't really impact on my enjoyment of the game.
My second play through as Russia was fairly swift as the Japanese sued for peace, and for the most part I just had to watch my forces grow and hit the end of turn button. No crashes that I can recall.
However I've had to abandon my 3rd play through as Japan, as it pretty much crashes every turn. The main difference I think is that I discovered the joys of ship to shore bombardment! The black bombardment icon flashes, and the game almost invariably crashes before the turn resolution can be completed.
I've not set my system for error logging, so can't attach any log files for you, but I'd be willing to figure out how to do that for you if it would help (not done it before). I have tried reducing maximum graphics size from setting box (4) down to (3) but it made no difference. I'm not willing to reduce down to (2), as all the sea zone textures disappear. I always disable CPU sleep, as I have found that prevented crashes for me in RoP and AJE, and I have maximum memory availability for caching.
Does anyone know if there are known problems with the Russo Japanese scenario, or the bombard display? My PC is about 18 months old, and has so far been able to play anything I've bought recently with maxed out settings, but I'm worried that I might not be able to play the big scenarios and grand campaign, if this small campaign crashes out.
