Re: Enabling blur in kwin slows down the desktop effects
GeForce 8400GS - CPU AMD64 AthlonX2.
KDE 4.5 - display FPS enabled in desktop effects.
Blur enabled: 30 FPS.
Blur disabled: 70 FPS.
I do not think the problem is related to nVidia drivers; the real problem is that whoever created the blur effect seems not a programming genius ...
