EDIT: Seems to be only Ishiiruka, but strangely even old versions which I used 2 weeks ago were then much faster o_O

You're not the only one experiencing the massive slowdown. It's not an NVIDIA driver issue, but a problem with Ishiiruka (as it happens with ATI/AMD GPUs as well).

There's a HUGE performance hit in Ishiiruka with EFB to RAM (compared to master). In nsmb, for example, the logo screens, some menus, transitions and other less demanding areas barely reach 60fps, while in master they run at up to 750 (!) fps.

Another issue: with the OpenGL backend, the FPS counter is not shown, even when the option to show it is enabled. Also, OpenGL in Ishiiruka is slow as heck.

Good to hear it's not just me. The issue is not just with EFB to RAM (I don't use that option).

kirbypuff: opengl is outdated in ishiiruka, i recommend to use only dx11 or dx9. can you give more detail on the slowdowns you are describing.

StripTheSoul: your issue is seems to be caused by the latest nvidia dirver i have various reports that they cause slowdowns on ishiiruka, will try to test them on a friend machine this weekend.

Also, the Direct3D9 backend in Ishiiruka is way slower than Direct3D11 at high IRs (above 4x)

Yeah, I guess it's the same thing I noticed here: https://forums.dolphin-emu.org/Thread-unofficial-ishiiruka-dolphin-custom-version?pid=343477#pid343477

Hmm, if it's an issue with the driver, it's not just the very latest one, though. I installed 344.11 now and it's still just as slow.

kirbypuff: that is because dx9 uses multiple rendering passes to emulate things that dx11 do in a single pass. dx9 is faster for lower IR on cpu limited machines.

I think I found a bug in the latest versions of Ishiiruka when loading custom texture packs only under DX9. Games that use them crash the emulator after the initial white screen that shows you how to use the wiimote. Versions 316a4c5 and fcf3f14 both show the bug.
aafb2fa seems OK.

You could at least fix the FPS counter, so users could see how big the performance gap is and avoid using it.

nsmb @ 6xIR with EFB to RAM (Direct3D11 backend) : the performance in areas that are extremely light (menus, logo screens, level overviews, transition effects, static 2D screens) is abysmal compared to master. The lighter the load, the slower Ishiiruka gets. It's weird to see heavy parts (geometry-heavy levels) run extremely well (60+ fps) while menus/maps that should run at 100fps running at a dog-slow ~40fps. Master is way faster with light loads.

P.S. And what was the reason for removing the exclusive fullscreen option from the Direct3D9 backend? I didn't experience any issues with it and it offered a nice performance boost. Please add it back (even as an .ini-only setting)
