FPS trouble, MKD

[Xenon]

Well firstly hello all and thanks for the great emulator.

I'll try to keep it short:

I'm having slowdowns in Mortal Kombat Deception, because my FPS is 30-40 when there are characters (fighters if you may) on the screen in the Arcade mode, in the Puzzle Combat it's 50-60 FPS (which is good). When the camera isn't looking at the characters in the Arcade mode it's 50-60 FPS as well. So my question is: am I doing something wrong? :S

The game is pretty much playable (I can also upload a video of Arcade gameplay if it helps).

I tried fiddling around with configs and still no good result other than more FPS drops (5-10).

Also, there's some rendering problems (shadows); they are sometimes either some squares or a set of lines.

My specs: AMD Phenom ™ 9150e Quad-Core Processor (4 CPUs) ~ 1.8 GHz

2 GB RAM

ATI Radeon HD 3200 Graphics

If more specs needed, that's fine with me

you should be happy.

1,8ghz phenom is very weak compared to what you should have to run games at 100% speed the whole time.

the only things you can do :

- enable dual core
- enable idle skipping
- disable all dsp(audio) settings
- disable EFB in graphic settings (this may result in messes up graphic)
- use 64 bit version on 64bit OS
- use DolphinIL.exe (this may result in more crashes)

Thanks for the reply.

I've done all the things listed and it gave me a boost - 150-300 FPS at the beginning, in-game it didn't do much though. 40 FPS average.

I'll try DolphinIL.exe later. What does it do exactly?

Oh and, Quad-Core 1.8 isn't weak, but yeah I am happy with it anyhow.

(Oh and I am currently using older version of Dolphin I think, therefore the music disappears sometimes and there are some graphical artifacts...)

quad core wont help you, dolphin only uses 2 cores.

That means even a cheap 2ghz dualcore would run dolphin faster.

also keep in mind that some games dont even run perfect at 4ghz, so your result for 1,8ghz is really good.

Quote:I'll try DolphinIL.exe later. What does it do exactly?

it uses another(newer) method of the just-in-time recompiler.

That means, it maps the instructions of the powerpc from real gamecube to your processor.

This new method is sometimes faster but also less stable at the moment. So if crashes a lot with IL there is not much you can do about.

clock for clock, a phenom 2 is slower than a core 2 duo. However, a 4ghz pentium 4 would get destroyed by a phenom 2. It's all about clock for clock.

[Iulius]

its all about the game.

- wind waker wont even run great on 4ghz c2d
- old stuff like harvest moon will probably run great even on 2ghz singlecore Pentium 4

i think mortal combat is more in category 2.

Oh, so there's no Quad-Core support yet? Too bad

...Any updates for Dolphin to utilize Quad-Core in the future, perhaps?...Meh, just dreaming.

Anyhow, DolphinIL....I've tried a newer version of Dolphin the other day and the game text was missing...Crap. :/

i dont think there will be much of a speedup with quadcore, even with implementing that.

The main slowdown comes from recompiling and executing the powerpc instructions and this is not going to be faster with parallel work.

imagine that 1 child needs 9 month till birth. you cant make this faster with 4 women.

there will always be work that cannot be done parallel at all, no matter what intel and amd want their customers to believe
