Emulator runs super slow since having the second CPU installed

[CosmoCortney]

Hi,
a month ago I got my second CPU and later I wanted to play with dolphin.
But all games run extremely laggy since having the second cpu installed.
I set dolphin's relation to cores/threads od the first cpu only, but no changes.

any advice without disabling the second cpu in the bios?

EDIT: some older revisions (3.0) run fine

Dolphin only runs on one CPU, on two threads. As for your video card, read this: https://forums.dolphin-emu.org/Thread-minimum-specs-video-card
Try these to run faster:
1) Update drivers, Windows updates, DirectX Web updater, and latest version of Visual C++ (some components may be missing)
2) Make sure under Power Management in Windows you're running in High Performance. Also, make sure you have a high performance profile set in Nvidia Control Panel
3) Use the OpenGL backend on one of the latest dev builds, as it is faster than D3D. (Depending if you're sticking with Nvidia, you should use Vertex Streaming Hack (for Nvidia cards only) on the Master builds, but it's not needed on the latest dev builds due to some updates in OpenGL extensions for AMD and Nvidia cards)

Either you're very wrong or some very big changes happened whilst i was away

Oh? Unless you use LLE on thread, Dolphin has never used more than 1 CPU and 2 threads

There is core-jumping, where Dolphin will cycle through using different cores, but it's only using 2/3 simultaneously.

I'm not sure why you say 1 CPU, but yes dolphin will only use 2 cores

[KHg8m3r]

CosmoCortney said in the OP that they installed a second Xeon CPU, and didn't see any speed increase, so I specified

[ExtremeDude2]

If you have 2, 1 core CPUs then yes you will see a speed increase

[KHg8m3r]

That may be true, but there's no CPUs like that that will run dolphin anymore
The CPUs in question are each octa core with hyper threading

16 cores/32 threads is kinda useless unless you're actually running a server or doing a fuckton of video encoding, y'know. If you want better Dolphin performance you're seriously gonna need to swap that motherboard out with a recent single-socket one, e.g. a Z87, and pop in one of the ridiculously-overclockable CPUs we're all fans of here on the Dolphin forums, e.g. the i5-4670K. I hate telling people their hardware isn't good enough, especially since the good stuff costs another $400 or so, but 'tis the truth.

Except most Xeons from 2001-2005 and some from 2005-2007. Seriously though there are a lot of single core xeons that will run dolphin. It's just that nobody uses them anymore.
