Ampersand, I saw your first post, and I applaud your username. Welcome to the depths that are the DF forums. (being a dwarf game, depths == good)
Anyway, downloading 40d5 + testing with my trusty 40d init.txt/raws/savegame because nothing else has changed (I HOPE =S) since then.
tests follow;
Windows XP, 2.66GHz processor, 4x4 fort with minor river, 2 yrs in, [SPEED:1] dorfs (no shame), giant size windowed mode (125x50 default font blackspace off)
PARTIAL PRINT OFF, START UP ANIMATION SKIPPED
on start up, anti-virus blocks dwarf fortress.exe from "program library injection"... as usual... everything normal, exit to test PP.
Oh yeah, and the menu doesn't loop over anymore ^.^
PARTIAL PRINT ON (2)
Usual "program library injection" error, prompt for full screen normal...
It looks like the screen isn't updating from black.
If I move the screen around, it takes the image of whatever was there, unless it was already there, in which case nothing happens.
LOL, It still manages to take up 10% of my CPU though!
I'm able to exit by hitting up then enter like I should. I think I MIGHT have seen a flash from the normal menu before it finishes. Yep, I confirmed that, I did see at least a single (graphical) frame before it quit.
Now testing multiple keys in fortress mode with PP off.
Saves/raws are compatible -I always worry about that so phew.
18-25 FPS depending on how many idlers I have 40d5 (will test save in 40d later for comparison)
Ok stable benchmark of 16-21 FPS with all of them working on a rather large paved road. FPS chokepoint seems to be pathfinding as all 27 dwarfs try to path through my 3-tile wide entrance and 3x3 staircase down to a quantum stockpile of stone. (Oh yeah, the stockpile has a single door so that's the choke. I saw 3 of them in the same tile. xD Still 40d5)
No problems noticed going between z-levels, playing as I usually do works fine... noticed that both of the children are referred to as "it"... that's not new though =P
No problems noticed with minimize/restore, though it doesn't have PP on, so big whoop.
Ok then... saving+quitting goes smoothly.
Now testing 40d save for fps comparison. (all other variables held the same)
Partial print off: 15-21 avg 17
Partial print on (2):18-27 avg 22
Data collection complete-no more edits to this mangled post.
I sincerely hope this helps a bit with de-velopment-bugging.
