Have you tried that on windows using same hardware?

I forgot to mention that it's "Prince of Persia - The Sands of Time".

Yes, I run this game successfully on Windows Vista x64. My linux distribution is openSUSE x86_64 (if this is important).

ok, I did mention it in the text :P

On Windows, is your cpu also running at a lower frequency?

yes, power saving is active and adjusting core speed continuously (between 1000 and 2400 MHz)

Created attachment 13634 [details]
Log running the game

attached is the log I took when I ran the game starting with "Powersave" CPU frequency policy and switching to "Performance" once a new game was started.
(Leaving to dynamic sometimes shows correct timings - this is a save way to reproduce it, although I have not tested a similar behaviour on Windows)

I'm guessing it depends on the difference of frequency when the game (application) started and the in-game cpu frequency.

maybe I should also mention, that the only thing running at normal speed when this happens is the game's music and sound effects

Please retest in 1.1.9.

retested with wine 1.1.10 - bug is still present :(

I'd like to add some more comments about the details of this bug though:

- game started with CPU@Powersave
  -> game runs at normal speed
- game started with CPU@Powersave, changed to "Performance" in the game
  -> game runs too quickly

- game started with CPU@Performance
  -> game runs at normal speed
- game started with CPU@Performance, changed to "Powersave" in the game
  -> game runs too slowly

- game started with CPU@Dynamic
  -> game runs too quickly

Please don't change the original reported version.

On the net you will find reports of similar issues for Sands of Time on Windows. Seems that the game has problems with c'n'q and/or multi core machines. However, I wasn't able to reproduce the same error in Windows. Perhaps recent Windows c'n'q drivers come with workarounds for this.

I just started playing The Sand of Time with wine-1.1.14 and did not discover that problem so far.
I use an AMD Athlon 64 X2 4200+ and the governor is set to "ondemand" and the game runs pretty fine.

Forget that. I played the game again today and discovered the same behaviour as stated in comment #9

I can confirm. When the ondemand daemon is running, the game runs far too fast. Stopping the daemon with 'sudo /etc/init.d/ondemand stop' before running the game allows it to run at the correct speed (and making the game playable).

Another game which is affected is Beyond Good & Evil. Audio and video are out-of-sync when cpu frequency scaling is enabled.

i had same problem at windows xp pro 64 bit with AMD Authon 64 X2 Dual Core 4400+ 2.3 GHz. at that time i checked gaming forms and i found this solution: make the game use only one core. it's probably programmers didn't really think of multi core systems.

Same Problem like comment #9 im DeusEx 1
(wine 1.2 rc 6)

Maybe it´s not an wine Bug. 
There is a workaround in the DeusEx howto. 
I hope in some day there is an switch to disable the dynamic clock speed while playing.

then why does it work on Windows (same machine?) - although cnq driver workaround mentioned in Comment #11 seem reasonable...

this might not be the desired behaviour - imagine old games not using all the power modern machines got - they don't need to waste energy then...

I'll however test with the newest wine version soon - also with the program attached to a single CPU core...

*** Bug 16327 has been marked as a duplicate of this bug. ***

I don't think that this is a wine bug - its a fault of the Prince of Persia engine. Beyond Good and Evil also uses this engine and has the same problems on Windows (XP or 7, doesn't make much difference).

This ticket has not been updated for over 900 days. Development recommends
to check the status on your bug every release or two and let to be known if the bug is still present. If not, mark it fixed. If you are no longer able to put effort to this ticket, you can abandon it.

Is this still an issue with 1.7.4 or higher ?

Tested Beyond Good and Evil on Wine 1.7.11 - audio and video are always in sync, even when the CPU is throttled.

I tested it with running my CPU throttled:

echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

and afterwards with the full power:

echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor


(I noticed that the game is not playing some of the menu sounds when the CPU is throttled, but there is another bug for this already opened. This bug can be closed)

Reported fixed.

Closing bugs fixed in 1.7.12.
