dolphing v3.0 graphics

[nourish]

anyone know why the latest versions of dolphin 3.0 and onwards have terrible graphics?
when i try SSBB on the older versions around r7xx you get this crisp hd graphics, where as the latest version u get graphics that look like they are 64 graphics?

anyway to get the nice hd graphics look on the latest version of dolphin? running older version before 3.0 give me this constant error

which turns the screen to black and all you can do is hear the game in the background. only way to fix it is to either fullscreen on make the game window to resolve it.

Is your GPU overclocked? If yes, try to reduce the amount of MHz when you're overclock. This problem occurs at my notebook too, when i overclock my GeForce GT 540M too high.

Try updating your drivers for your GPU. Might as well see that you have the latest DirectX as well (if you're using the DX9 or DX11 backends). Also, check to make sure your GPU's temperature is doing alright. At any rate, I don't think this is specifically an issue with Dolphin, rather in running the latest revisions of Dolphin you're encountering other issues.
