60FPS but with slowdowns?

[Zero]

Hi, I've been trying out Dolphin with Mario Kart Wii and I get 60-61 FPS in game but for about 5% of the race I get random lag.

I've been playing around with the settings and no matter what I do this lag won't go away. I've added Dolphin to high performance in the Nvidia Control Panel.

Strangely, it lags the least when I crank up the settings the most, I don't understand why. But I have it at Direct3D11, 4x resolution, 16xAF, 8_32AA.

Is this normal for emulating titles? Or perhaps it needs some tweaking?

SPECS: i7-4790K @4.5GHz, GTX 770, 8GB RAM.

Disable AA and overclock. I´d also update to latest dev build.

Disabling AA doesn't really change anything at least, I could be wrong here but I notice more lag with it off.

I'll try the dev builds and see how it goes.

Thanks.
