Re: 260GTX nvidia-drivers-190.42-r3 - powermizer issue
Same here - I use an Asus GT240, PCI-Express, 512 MB GDDR5 card.
Powermizer uses only the middle (405/324) speed - which has tremendous impact on speed, compared to the 1.7GHz mode (used perfectly under Windows - so this is a Linux driver bug).
Due to this bug, glxgears runs at a ridiculous (for this class of card) speed of 4500 fps.
Please fix this, NVIDIA.
