DF input slowdown with dual core
« on: November 14, 2007, 08:47:00 pm »
Hmm, I was writing a topic complaining about slowdowns, but I figured out a fix and then I hit some key combo that closed my browser by accident.

DF was getting slower and slower on my current fort, so I looked at task manager to see what was the matter, if another process was causing problems.  DF was not using 50% CPU like I'd seen in previous versions, it was actually kind of low.  I made a new fort, 3x3 map, and FPS counter was bouncing between 30 and 50 while paused, only 1% CPU usage.  I tried upping DF priority but that didn't help.

So, I changed the affinity to CPU 0 only in Task Manager, now its 100 FPS like it should be on a new small map.  Keyboard input isn't "bouncy" like it was before.  I don't know if it was the recent windows update, or 33a that caused the change.  I'd suggest changing CPU affinity for anyone with unexplained slowdowns.

Vista and no such problems here. I don't know why DF runs better on Vista...

I'm getting a total of 53-55% usage of my dualcore, viewing through Process Explorer. The main DF thread uses 50% like it should, plus some additional threads for visual output and sound use up some more.

Setting DF to one core worth of affinity (and everyother user process to anything but that core) is actually a good idea anyway, just so you can dedicate a whole core to DF.
