choppy anim

[Skrzynka]

Hi,
I'm trying to get some game (Settlers 3) to work on Wine (updated 
sources recently from git). If possible, I'd like to ask for some clues 
for a start:

1) the issue is choppy animation - the frame rate is abt 1/sec while the 
cpu load is low. However there are random periods when there seem to be 
about few frames per second (and cpu is laoded 100%).  I tried measuring 
the time between call and return of DLL functions in relay.c. The only 
thing that looked suspiciously was WaitForSingle|MultipleObjects having 
times like 200-500ms. I also tried adding some delay to 
WaitForVerticalBlank in ddraw.c but also to no effect.
Where should I start looking for the problem - some events or callbacks 
code? which?

2) when I run it from within winedbg i get lots of exceptions (no matter 
if app was started from winedbg or it was attached later) and no matter 
what combination of pass/continue I do, the app crashed with some msg 
box about exception or structured exception. Any pointers to docs on this?

Any suggestions will help greatly.
Thanks & regards
  Piotr
