Also, it seems this is very cpu intensive spot after all- I wasn't able to reech 60 fps no metter what I tried.
EDIT: When I think about it, I do have weaker gpu then Garteal and xcyper.
If anybody would be willing to reset their overclock and test, that would put this issue to rest ( with the exception of framelimit bug, of course )

What do you theorize would happen if one would reset the overclock?

You might not be able to keep 60 fps even with framelimit off, and get exact same results as me, which would mean that this has nothing to do with gpu, but is cpu speed related.
Or,if you could still keep 60 fps with framelimit off, then it would mean this is gpu related.

- nevermind, please delete this -

I might figure out this problem
@xcyper33 has the same speed as @rpglord , that mean @xcyper33's CPU is not at 4.5GHz when Dolphin is running (might be at 3.1GHz or sth)

You can go to bios and disable "Intel Speed Step" or force maximum CPU speed / multiplier via ThrotleStop to make sure your CPU is at 4.5GHz all the time

Actually I don't have the same speed as rpglord, it is a little better than his, but it still isn't reaching 60fps at certain 'angels' in certain areas of the game.

Also, I do not want my CPU to be running at 4.5GHz at all times, as that drastically decreases the life of a CPU.

With decent cooling and sensible VCore, then although it will reduce the CPU's life, it will still last long enough to be completely obsolete by the time it breaks. It should have 5-10 years life vs 10-15 years. Within 5-10 years, there's no way you'll still be using that CPU, as there'll be much better ones available.

Here are my results for this.
CPU: i5 2500k both stock and OC to 4.5ghz.
GPU: GTX 660
Ram: 8GB DDR3 1600
OS: Windows 8 Pro x64
Game: NTSC
dolphin 3.5-1034
All tests where done on D3d9 4x IR 0 SSAA 16x AF with Per Pixel Lighting enabled. DSP LLE

Stock



Stock + LLE on Thread



OC EFB to Texture



OC EFB to Ram



OC LLE on thread EFB to Texture



OC LLE on Thread EFB to Ram



A few notes:
All the OC tests would eventually hit 59 fps if left alone long enough.
I was surprised by the speed up using efb to ram. I didn't show it in the stock tests because just standing there it didn't make a difference but running through that area had less slow down with efb to ram. EFB to ram + LLE on Thread is the only way I could get 60 fps with only about a 2 fps drop running through that area, sometimes no drop depending on camera angle.

Thanks to contributing, this clearly shows that this is cpu bottleneck after all
