Dolphin, the GameCube and Wii emulator - Forums

You don't have any idea what you are talking about. Optimization isn't the only thing that affects performance. Some tasks are just more demanding than others. Dolphin happens to have some extremely demanding instructions to run in certain games, such as SMG 1/2 and TLS. FSX might be CPU intensive because it isn't well optimized (I honestly have no idea) but that means nothing if the task it is running is less demanding than what Dolphin is doing.

Try using LLE audio. You will see why you need a new Intel CPU to run a lot of games full speed.

I already mentioned I am running LLE audio. The loss of speed is almost minimal.

But no, as with any flight simulator, the multiple tasks running have no comparison to any emulator, there are thousands of variables running in a simulator.

I'm sorry my CPU can handle things they are not supposed to? Lol.
Get over yourselves, intel is not salvation.

I doubt about that
I couldn't get Skies Of Arcadia run fullspeed with LLE on both system (desktop & laptop)
Fullspeed = no slowdown
On the first cut-screen , the framerate jump from 30 FPS down to 15 FPS

Edit : Nevermind me then we're getting off topic here . If you're satisfied with your CPU performance , it's fine , we'll leave it like that

I don't really care about your CPU performance; it has no effect on me. I will still argue that Dolphin can be much more demanding than your flight simulator depending on the game and situation. Running TLS requires a 4.2 or 4.3 GHz ivy bridge, and even that won't get you full speed with LLE.

I don't see why you act like it's a big deal to say a program is more CPU demanding, it is not a quality whatsoever. You need to stop acting like intel is superior.
There are no applications that are developed to function better with any CPU, and it is ignorant to say an application REQUIRES ivy bridge. I'm sorry, but that is just retarded.

My point is that if my cpu can run an incredibly demanding application such as FSX, which I assume you are not familiar with, it shouldn't have problems at all running dolphin, which is true. Most intel fanboys have not even used a computer with an AMD chip in their lives, they only listen to benchmarks from toms hardware. It's sad really.

And I am saying it is not necessarily true that a CPU that can run a program like FSX should run Dolphin fine. The requirements for Dolphin are very different then most programs. The use of only 2-3 cores and the need for extremely high performance on each of those cores is very unique, and the way in which the crew need to interact is unique. I am saying that you can't just say "my CPU runs X demanding program fine, shouldn't it run dolphin fine?"

This statement makes zero sense because that is not what I said. I said that running TLS (full speed ofc) requires an ivy bridge at 4.2-4.3 GHz as a reference for the power required. It can also run on a 4.5 GHz sandy bridge. It cannot run full speed on any current AMD CPU or any Intel CPU before sandy bridge full speed that I have heard of.

Then perhaps you didn't do a very good job configuring your computers hardware to work together with other hardware properly. I take you built your own computer?

Scratch that, Just saw that your system has 16gb of ram. I'll go back to the theory that you didn't configure the way your hardware works properly.

Every single person who has ever run TLS has reported that figure to be accurate.

My hardware works fine. I don't see what this has to do with the other points I made at all.

Dolphin doesn't need an i5 or i7 to run Dolphin. As long as the processor supports SSE2, it'll run (there's even a patch to get around that). What's more relevant is how fast the application will run. Currently, as others have pointed out, there are some games with LLE audio that only overclocked Sandy/Ivy Bridge chips can play at fullspeed consistently. This has been a widely observed phenomenon, though you're free to provide evidence to the contrary.

Erick Wrote:But no, as with any flight simulator, the multiple tasks running have no comparison to any emulator, there are thousands of variables running in a simulator.

I really don't know what your argumentative point is in saying flight simulators have thousands of variables. Variables are just values stored in memory. You could make a simple "Hello World" program with thousands of variables. The number isn't what's important; it's the type and frequency of calculations you perform on them.

Dolphin spends a lot of CPU time translating instructions native to the GC/Wii into something your computer can understand and process. Emulators are incredibly complex programs; you can verify this by looking at Dolphin's code. It's not outside the realm of possibility that Dolphin could in fact be more demanding than most flight simulators, depending on what game it's running and under what conditions (The Last Story with LLE audio + EFB Copies -> RAM for kicks).

Erick Wrote:You need to stop acting like intel is superior.

People here are very careful to specify that Intel CPUs are better for Dolphin. Other applications (Adobe's stuff, movie editors, encryption, compression) are covered by other benchmarks. The community, as a whole, agrees that Intel's most recent chips perform better, clock-for-clock, than AMD's current offerings. This has been consistently reported by users doing comparisons. Like I said, you're free to post your results (and this is something we very much encourage) if you feel that we have been mislead.

This is very much false. There are plenty of applications out there that can run inline x86 assembly for certain operations. However, the developers might not know the equivalent assembly for different platforms, such as MIPS or ARM, so they code those operations in C++ when porting. The C++ gets translated into MIPS or ARM assembly, but there's a good chance the compiler will generate slower code than could be made by hand. In these cases. The program can be viewed as being programmed more efficiently for x86 systems as opposed to MIPS or ARM.

It depends on why FSX is demanding. If it's doing a task that similar or equivalent to Dolphin, your point would have more standing. But FSX isn't constantly recompiling code. Let me illustrate this with an example:

It isn't very hard to make a small program that could max out all four of my cores. I just need to create 4 threads and tell each thread to do something (e.g. add 1 to some number) without stopping. I could even have it dynamically grab more memory (RAM). In this sense, since most of my resources would be used, it's technically more "demanding" than Dolphin. However, it'd be very short-sighted to claim that Dolphin or even FSX should run just fine since my computer can run this (rather asinine) little program. They're all doing completely different tasks. You need a program that's very similar in nature to Dolphin to start drawing these sorts of comparisons.

Now i understand what's going on
He was misleading "LLE backend" with "DSP LLE on Thread" .
He suppose to dump 2 files "dsp_coef.bin" and "dsp_rom.bin" , place them on Dolphin\User\Sys\GC then enable DSP LLE compiler via Dolphin like this

With LLE backend enabled , he should get slowdown on cutscene

With HLE + Disable Framelimit . I got more than 60 FPS
