Should changing graphics cards alter emulator performance?

About two months ago I got rid of my Nvidia rage card, and upgraded to a Radeon 9200. Since then I've noticed that project 64 has been behaving oddly. Smearing or blurring graphics and such.

Games played perfectly fine on it before with the inferior graphics card, but now with the superior one, games are choppy, and graphics tend to smear and blur often, especially on horizons. I attached a picture of the kind of 'smearing' I mean, since I don't know the technical term.

I don't really understand most of the advanced graphical opions, and the limited tinkering I have done has only caused other problems, so is there another N64 emulator program that is friendlier with a Radeon 9200 card, or am I missing some option I should've tried?

I've tried using Rice's new plugins, but then when I boot up the emulator, it tells me "Failed to load plugin", and won't let me utilize the plugins. It's driving me nuts.

you need to have the msvcr71.dll and the msvcp71.dll in your main plugin directory. You can get these from 1964 0.99

Not really seeing a change. Should I select one of them as my video plugin? It's not showing up as selectable, but it's also not griping that the plugins aren't working.
