Slow Fps in some games with diferent version d2x cios about d2x-cios HOT 4 OPEN

Do you see the same issue with d2x v10 beta52 or d2x v8 final?
And launching the original dvd from the disc channel?

I am now use d2x v 10 beta52 and all ok. Before I am use d2x v8 it too ok! I am 
launching games from HDD 500gig Seagate.

strange.. i didn't notice the difference. played same stage with 'zangeki no 
reginleiv' using r52 & r53-alt, both have frame rate drop when the screen full 
with giant creatures (external HDD Seagate 320gb usb 2.0, CFG loader v70 
r50,cIOS v10 slot 248 base ios55)
nothing to do with cIOS, right??
i think maybe it's Wii GPU/processor issue (CMIIW)
(sorry for my English)

Example. Resident Evil: Darkside Chronicles. Stage 7 from Resident Evil 2. I am 
play on Usb Loader Mod r50. If I am use d2x 8 or d2x 10 it look normaly fps. If 
I am use d2x 9 or d2x 10 alt 53 I see visibly drop fps. See slovly in something 
time. I understand what in something games on wii it happen because gpu or 
processor . But in this game it happen only on d2x v9 or new d2x v10 alt 53. 
Maybe someone cheak this. I am have external hdd Seagate GOFlex 500gig USB 2.0.
