System Information
Operating system: macOS Ventura 13.5.1
Graphics card: Apple M1

Blender Version
Broken: (4.1.0, 6b0769c448c8-darwin.arm64, alpha-main, 2023-10-17)
Worked: 3.6.5

Short description of error
The viewport performance of Eevee Next is much worse than Eevee, When playing the timeline I get like 6fps while if I switch to Eevee is 29 fps.
Exact steps for others to reproduce the error
Just open Blender 4.1.0, switch to Eevee Next and orbit the camera or play the timeline

I see the same performance drop, more specifically the shadows option seems to be the main culprit. Enabling that gives about 1/3 the frame rate compared to when they are disabled.

Testing a bit more it seems to be related to the samples, it stalls while computing the samples and when finished it performs all right

I don't see any significant improvements compared to earlier builds.

I can confirm that EEVEE Next is slower than EEVEE Legacy, although the extreme values reported were not observed.
To test this, I had to use a heavy scene like the Barbershop because, with the default Cube scene on MacOS M1, the FPS appears to be limited to 60, regardless of settings.

Additionally, I compared the same scene on Windows using a Radeon RX 480, and the slowness exhibited a similar factor. Here's a breakdown:

	EEVEE Legacy	EEVEE Next
Windows 11 - Radeon RX 480	9.2 FPS	4.9 FPS
macOS 14.2 - Apple M1 1.2	4.2 FPS	2.1 FPS

It's not surprising to me that EEVEE Next is slower, as it aims for a more realistic rendering.
Another observation is that the shaders take considerable time to compile on MacOS, and we still encounter the 'Optimizing Shaders' step.

@JuanRomero, could you try the latest daily build: https://builder.blender.org/download/
Also go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue.

(@fclem, do you have any insights on this issue?)
