Exclamation Poor 8600GT performances with NeverWinter Nights

I just replaced my 6600GT by a 8600GT (leadtek 8600 GT extreme). Nothing else had changed in the system hardware or software configuration. I use the latest nvidia 100.14.19 driver for both cards and I have some strange problems:
- The amount of memory detected is 512Mb, instead of 256Mb (same problem under Windows thus).
- Some 2D operations like rectangulars fills or blit seems slower than with 6600 GT, but it is just a feeling
- The FPS displayed in NeverWinter Nights fell at 10 to 12, instead of 25 with 6600GT, and this, whatever settings or resolution is used ! This one puzzles me.
- The bios version is not reported in /proc, but is correctly reported in nvidia-settings !
- Other than this, the card works well, including (the useless) glxgears where I get 15000 FPS.

The problem with NeverWinter Nights and 2D performances are really a problem for me. Any idea or fix anyone ?

I attached the bug report in hope it may helps

Question Re: Poor 8600GT performances with NeverWinter Nights

The problem with the amount of memory reported has been explained by Nvidia in a recent post in another thread.

The OpenGL performance remains. I suspect that one of the OpenGL feature used by NWN is poorly implemented on the 8600GT. Is there a way to time the OpenGL calls used or to help find out what the probem is ?

Well as it seems NVidia is not interested in your problem - you've bought the card and spent the money :-/
