Is anybody else experience subpar scrolling performance throughout the OS? Safari is particularly brutal. So I downloaded an app called gfxCardStatus that allows you to bypass the automatic switching between the integrated card and the discrete. Locking it to the discrete card brings the performance to at least an acceptable level, but it's still not anywhere near the buttery smooth performance I was getting in Mavericks.
