That's really cool, does it work in Metroid Prime? (E.g. Limiting frames to 30 instead of 50/60, keepinig speed at full)

i dont know, only got the 4 games i wrote for testing.

but you can compile it yourself to test it.

at the moment its 75% chance that it works


edit : made a new one.

the old one changes waitingtime only once a second.
The new one uses each new frametime for cpu-suspend.

This produces much more stable FPS + will not cause any slowdown if game runs slower then choosen framelimit.

still, SSBM does not work. other 3 games work very well.

Code:

[b]static u32 targetfps = 30;
    static u64 old_frametime=0;
    u64 new_frametime;
    s16 wait_frametime;[/b]

    frames++;

    [b]new_frametime=Timer.GetTimeDifference()-old_frametime;

    old_frametime=Timer.GetTimeDifference();

    wait_frametime=((1000/targetfps)-new_frametime)-1;
    if (wait_frametime>0)
        Common::SleepCurrentThread(wait_frametime*2);
[/b]
    if (Timer.GetTimeDifference() >= 1000)
    {
        [b]old_frametime=0;[/b]

looks great, good job

[Iulius]

included it into main config window.

Few screens attached.

to compare : with "other audio on" its 18fps with 100% cpu use


           


still need help with the thread management.

it seems "CurrentThread" isn't enough for every game. but i have no idea which threads are running and how i can make them go to sleep.

can you compile the lastest version of dolphin, with that plz?
To test, if my games work too =p
and this is one great think that MUST be implemented in googlecode, to the official dolphin project =p

[Iulius]

i created a patch that can be used to compile yourself :

maybe i can provide compiled version later, if needed.

i don't know how to compile this, but isn't there a way to compile only the file tan contains this frame limit think, and than replace the file in normal dolphin?

[Iulius]

it would be possible for the same rev of dolphin, but as this changes 20 times a day, it would not make sense to do that.

i'll upload a compiled version of newest svn + framelimit tomorrow.

edit : got it

problem was the dualcore watchdog which was only checking every 4th frame at 60fps.

this means 3 frames were still running too fast resulting in too fast gameplay.


i updated it to check every frame @ 60fps and now SSBM also works

compiled file and sourcecode in first post.
