Default 460M: Clock changes make screen flicker & performance

Of course it's already quite positive that my asus g73jw works on linux, but there are two things I'd like to see improved:

1. A change in the performance level causes short black flickering on the display, which is absolutely inacceptable (e.g. with compiz). Setting the preferred mode to "performance" locks the performance level and helps but seems like a bad solution (batter life and heat). I had that issue with a Geforce Go 7800 and I hoped to never see that again. Any better solutions than that old and ugly NVreg_RegistryDwords="PerfLevelSrc=0x2222" hack?

2. Relative performance to windows 7 isn't as good as for older chips. My Geforce 8800M GTS performed better on ubuntu 10.10 than on windows 7 for my programs (10-20%) whereas the opposite is true for my 460M. It's about 20% slower than on windows. Is there hope future drivers will perfom better?

Yours,
Stefan
