Default Re: Where are the GeForce GT 240 Linux drivers?

where the same problem affects CUDA speeds (under Linux, 1/5th the speed of under Windows)...

What card model are you using? What speed do you get from glxgears?
I'm also getting ~4500 fps in glxgears, but still getting the same 550,800 GPUCurrentClockFreqs. The card is the XFX DDR3 card:

$ glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
22844 frames in 5.0 seconds
  Attribute 'GPUCurrentClockFreqs' (phoenix:0.0): 550,800.
EDIT: I don't know a good way to test CUDA as I bought the card for gaming.
