Emulator

I read in the forums, and the only thing that people say there is:

A: "your computer is to weak"
B: "but it works usually, only sometimes it drops"
A: "whatever, it's to weak, now stfu"

And that's about it. So, what you're saying is, that this is supposed to happen because Dolphin is only made for Windows? And my Linux is to weak? Or what exactly are you pointing me to?

It happens because the graphics drivers on Linux react differently than those on windows. I cannot tell you why/how, but they're less efficient than their windows counterpart. Using your NVIDIA will be better; in fact on Windows it probably automatically chooses it assuming you have optimus or something like that.

Your computer should be powerful enough with EFB2Texture regardless of Windows or Linux because it is a very light game. I tried profiling it but couldn't figure out what was working differently due to a lack of profiling features on windows.

The increased GPU usage could be causing overheating... but it could just be that the integrated drivers are different on Linux. NVIDIA says their drivers are the same on linux, but as I said, that's not what my testing results say.

I hope this is a bit better than "your computer is too slow" because that answer is simply unacceptable in this case. The most likely scenario is that Windows, due to higher use, has far superior graphics drivers, which lighten the load on both GPU and CPU.

So, what you're saying is, that this is supposed to happen because Dolphin is only made for Windows? And my Linux is to weak? Or what exactly are you pointing me to?

I'm saying simply that this is the wrong place to ask this. This issue tracker is for actual bugs; performance issues like this are ubiquitous and not really worth wasting developers' time on. (They mostly use Linux and hate Windows, by the way.)

tl;dr, set up your Nvidia GPU and make Dolphin use it. The Arch Linux wiki has instructions for that.

JMC4789, thank you for your answer. It makes sense and indeed the drivers could be an issue. I'll try to do some profiling myself and hopefully figure something out. Granted this is hard to do for someone else as this may actually only affect my specific hardware.

I actually forced the usage of the integrated card on Windows, and also would like to point out one more time, that while using the integrated GPU the performance on Linux is perfectly fine (talking of minutes of gameplay) until the frame rate dramatically drops instantly and permanently stays there until it instantly comes back up. So this is not the usual "slow-motion" on heavier load.

pauldacheez, even though I appreciate your answers in general, you seem to assume I'm some random whiny user who doesn't know about Bumblebee or Computers at all. I get your point regarding the "wrong place to ask", but how is this a performance issue (or better a configuration issue) when this happens in Linux only, using the very same configuration like in Windows? I didn't use the NVIDIA GPU in Windows (as stated above), and I also tried using it in Linux (Bumblebee). The results were different, but are totally unrelated due to the fact, that I tested with the integrated card in Windows.

Maybe I don't understand your arguments correctly, but in my opinion something bad that happens in only one of two distinct version (Windows vs. Linux here) should be called a platform-dependent bug. Obviously it's not a configuration issue if both versions use the very same configuration. JMC4789 pointed out this is probably a driver issue. So that means there may be a way to tweak the code to work better with Linux drivers in general. Who knows? If this is a wont-fix, it's still a bug, just not a one that can be fixed by Dolphin.

Anyway, as you consider this a waste of time, feel free to ignore it. I was just trying to help improving this project.

I'm not actually a developer, I just moderate the issue tracker. Same for JMC4789. (Though, now that I think about it, we've both made some very minor code contributions.)

Anyway, yeah, I'm pretty sure it's just that the Linux Intel drivers are slower than the Windows ones. (They are made by separate teams, one having less staff than the other.) You may or may not be able to profile it and narrow it down to one GL function; if you do, I'd recommend you contact some of the Intel developers on the Mesa mailing list, as the Dolphin developers obviously have no control over their driver issues.
