Re: KDE4 almost unuseable
Poor Render acceleration is probably the primary culprit here. Not much you can do about it except wait for nvidia to fix it, or at least accelerate the required render operations (nvidia does not accelerate all render operations AFAIK). One thing I noticed is that kde4 from trunk is a lot more snappy probably due to Qt4.4
Has anyone noticed any speed improvements with different InitialPixmapPlacement values? Oh yeah have you got RenderAccel enabled? Its usually on by default but some distros disable it.
