Emulator

sooo
mind giving more info?

one click on the link will give all the infos i guess :p

The solution to this issue:

backup your saves and uninstall dolphin completely, then install again lastests rev.
I did this at building and it got fixed.

That's not the solution to this problem. I've downloaded new and old versions of
Dolphin and the latest builds are slow while older builds run fine. It has nothing to
do with anything being "installed". I don't even have Dolphin installed anyway,it's
portable.

3545 broke speed.

Something broke the speed after R3851.

Games become slower somewhere between 3903 and 3928.

It's r3545. Everything got messed up there, lastest revisions are still trying to fix
issues derived from it without success, the worst being the famous "the game feels
slow, and stutters".

hmm, dont think it 3545. just tried. it has to be sth later.

Well...if it really is a big problem, then we could go ahead and revert it. That was
my revision. It really did improve performance for me (a common issue: "It works for
me." I'm using an ATI card. Are you all using NVIDIA cards?) Theoretically it should
be more accurate emulation too, but there are probably all kinds of timing and sync
problems that negate any accuracy improvements.

The purpose of r3545 was to let the game control when buffer-swaps would occur and
where the video data would come from. Before, a buffer-swap only happened when the
graphics FIFO received a "Copy to XFB" command, and then it would only display the
current EFB.

Try this patch. It restores the old behavior.

I'm pretty sure now it wasnt your change. maybe its somewhere around the nonpow
texture patch... ?

It's probably really sensitive to how fast your computer and graphics card is. Like,
the CPU thread may be racing ahead of the graphics thread or vice-versa. javimi,
please try "Use real XFB" and see if it makes any difference. Also try single-core mode.

just tried with your patch and xfb...

1. WaveRace Blue Strom works again and stops shaking -> Yay!

2. ^^ Maybe there should be an Option for that in Config, no ifdef :D

3. SMG with Patch without xfb - well if you compare it with 35xx version, even after
   your change it s**** now :) I only test the first 1,5M until the video starts. but
   older revs feel much better here. fps wise the difference aint so big.

4. SMG with Patch with xfb - same issue as above and about 7 frames less (40 vs 47)

My Sys:
Q6600 @ 3150MHZ 450*7
Nividia GTX 260

Speed of Cpu and Graphics should be equal.

No Nolan, using ATI here. That patch makes everything SO much more smooth and
stuttering free... +1 for revert. Try Mario Kart with Audio throttling enabled and
disabled for example, before and after the patch. Even Sonic Adventure 2, which plays
fullspeed all the time here, in the intro there was stuttering when Sonic appears
with blue light behind, now is gone...

I forgot, real XFB showed the same results. Running a Q9650@4GHz and an overclocked
ATI 4870.

5. MK Wii : less stutters with other audio, still slow (~40) but stuttering is gone

All in All it seems its just better synced this way :D

ok, finished testing and beging for u to revert it :) every game i tested wokrs
smoother and i see no difference in fps.

Nolan eventually submitted that patch, right?
