Sonic Adventures Battle 2 bug need help

[killerloader]

Ok, i used to be able to play this game pretty fasti dont remember the fps though, but recently the game has had a bug for me, peices of land were being transparent, and then slowing the game down loads, but its only slow while i can see the transparent land, well.. when i see where it should be

heres an image:


as you can see, the land is all bugged.
now, if i edit the settings, i think i got it to make it not transparent somehow, but it was still slow as

heres some info on how im running the game:
comp specs:
Intel hd graphics
2gb ram
320gb harddrive
intel i3 core
Windows 7 64/32 bit (both i guess)
apsire laptop

Dolphin settings and stuff :
idle skipping ticked
dual core ticked
framelimit: auto
jit recompiler
Direct3D9:
copy:texture
accurate texture cache: fast
scale:fractional
disabled fog
openCL enabled

and im running Dolphin R7426
Thnxs

[EDIT]
Ok figure out that disabling native-mipmaps makes everything not transparent again, but still does the same slow effect :/
