Had perfect settings changed then changed back. Don't work now

[xagesz]

After a day of tweaking I had finally managed to get my dolphin settings perfect. Then i decided I was not content. I changed this and that after reading a few threads and they actually made it worse. Undid what I had done and now my dolphin plays like crap.

I have mainly only been playing Gamecube. No need for wii.

Mario Golf, SSB, Double Dash.

All 3 worked PERFECT well pretty close. and now they barely budge.

What did I do.
