Disable native mips and emulate format change. Disable, enable cpu access and use the dx9 video. Set efb scale to 1x. That should help a bit.
ok i changed the settings and used what you said, but the graphic is lowered now and its more lagging i think, i have 40+ frames but it doesnt run smooth... super mario

and mario kart also runs slow ... ugh.....
I have the same problem with dolphin r7671, resident evil zero is slow. I tried all the configurations but it is always slow

While Resident evil rebirth is ok
