Can't undestand why running slow

[Halford]

Hi guys
Here is my specs

got this on my laptot:
-Intel HD 4600
-NVIDIA gt 750M
-i7 4700HQ
-windows 10 x64


and on my computer:
-gtx 550TI
-i7 old gen
-windows 7 x64

I have many questions but the first one is : is my laptop good enough for DOLPHIN 5.0?

the second thing is: i can't understand why super mario sunshine HD texture pack is running perfect at 30fps but why F zeo gx and the wind wacker are not running as good as this one.


for dolphin:
i got x3 Internal resolution
i tried to put it  lower but nothing change.



Then there is a thing that i cannot undestand:what is going wrong when i select DX3d11 and select GTX750M or GTX550TI ???it is always in OPENGL

i think gtx 550TI is enough powerful (or maybe i'm wrong correct me  i it isn't )
what is the difference between choosen OPENGL and D3DX11 with the graphic card?

here is the test on my laptot:
-SUPER MARIO SUNSHINE HD TEXTURE PACK=> Running fine no pb with 30fps
-SOUL CALIBURE II textures HD=> running fine
-SUPER SMASH BROS MELEE => running fine
-SUPER SMASH BROS BRAWL  => running fine

-MARIO KART WII => sometimes FPS a going down but no major pb

and the winners:

-zelda wind wacker HD and twilight princess=> total fail
-f zero GX HD=> under 25fps


Hope i put enough information.
Don't be afraid to ask for more about my specs


Sorry for the long post.

Fzero is super demanding to emulate. You actually need a pretty high clocked recent CPU to run that one at full speed.

Anyways use the latest development build hosted here.

I think it has a multi-dimensional performance gap between Dolphin 5.0 and the latest build: dolphin-emu.org/download
