Description

I recently upgraded to this build SEE FILES {PDF 1} from {Dropbox Link PDF 2} https://www.dropbox.com/s/eqw88iy09jknrty/P3rf3ct_Zer0s%20PC%20%209-2-2016.pdf?dl=0

What's the problem? Describe what went wrong.
So after; (and I timed this with a stop watch) 15 mins and 23 seconds the emulator starts to lag unbearably. I have tested everything on my pc even drivers - fresh install everything and nothing can circumvent it. Do not ask noobie questions like "Did you check temp" did you verify ram; did you try on a similar or exact pc?" the answer to all noob questions is YES. At any rate I am at a loss. So as an absolute last resort I am posting here.

What steps will reproduce the problem?

Have my exact build in theory.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

All of these https://www.dropbox.com/s/ldba8m620cth2l4/8.PNG?dl=0

What are your PC specifications? (CPU, GPU, Operating System, more)

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I will update this with a video.

Ok let me just try to clarify this - anything older than 4.0-9507? So on builds after 4.0-9507, such as all 5.0 era builds, it doesn't occur?

It looks like there's an object handle leak of some sort. The handle count is increasing steadily throughout the video, and as soon as Dolphin's closed the count drops by over 20,000.

Here is some stuff you can do to narrow it down: https://blogs.msdn.microsoft.com/dsui_team/2013/04/23/debugging-a-gdi-resource-leak/ (start at the part with task manager).

In case it is the cause or related: I can reproduce the permanently increasing handles here, too. I never experienced increasing CPU usage after extended play, though.

(It might still be caused by the open handles for OP if, let's say, he has some particular HID hardware connected that I don't have and which does processing for each open handle to its device or if he has some kind of tool installed that hooks into the controller communication (let's say Xpadder or similar) and that also does processing per open handle.)

If I switch off "Continuous Scanning", the number of handles allocated by Dolphin remains constant.

@P3rf3ct_Zer0 can you try with Continuous Scanning disabled? (You can click "Refresh" in the controls window during the game if it didn't detect the Wiimotes connected to the Mayflash DolphinBar at startup in that case.) Does the CPU usage issue still happen for you without Continuous Scanning?

Thanks for the hint, i can repro the handle leak with continuous scanning enabled, too. Note that it seems the performance problem occurs on the video around 0xffff handles in the dolphin process..:)
