at least this is a dupe.
you suffer from bad X11 performance on texture_prom_pixmap in the nvidia css
driver (or pot. any conversion method)

- have you ever checked your /var/log/Xorg.0.log (esp. have a look for "WW",
"EE" and "dri")
        grep -E '(EE|WW|dri|DRI)' /var/log/Xorg.0.log

- is X11 load high using the XRender backend as well?

- sure you're actually using the nvidia css driver?
        glxinfo | grep -i version
