For those who are having problems with the 40.41 I suggest trying to get hold of the 30.30 drivers. I have a number of machines with Nvidia cards ranging from TNT2 up to G3Force 4 TI4600 and the 30.30 drivers (which I believe were beta) have proved to be the best all round. The biggest problem with the 40.xx series right now is they are trying to technology with WindowsXP and Resfresh rates/Multimonitor support, and sometimes this new technology is causing issues with some machines. They have released new drivers on their website yesterday 40.71 which I am using right now. These drivers still have some issues with some games (main one being Age of Wonders 2 - but not as bad as the 40.41 drivers) so they might still have some issues with them. Also for those who have not got multi-monitors I would suggest turning off Multi-Monitor Hardware Acceleration. This has been known to fix a number of lockups, and other OpenGL issues which have appeared since the 40.xx series has come out. In regards to no new drivers for older cards... Correct in essence. There is no new updated enhancments to the driver set for the chipsets used with TNT2, and Geforce 2MX, and Geforce 2. However - There are Unified Drivre enhancments which can benefit older cards just as much as newer cards. A primary example of this is the Multi-Monitor Hardware Acceleration support (when working will make WindowsXP a true Mutli-Monitor machine with OpenGL on both monitors) and also the introduction of Direct3D WindowsXP/Win2k Refresh Rate manager (since Win2k, and WindowsXP all set directX at a refresh rate of 60hz for games and DirectX3d/OpenGL applications). In regards to Windows no refreshing: Pro Pack SR2 had the same problem with me - it was fixed in SR3 - so I wouldn't be doubtful if simular problems with Poser 5 will be fixed when SP1 for it is released (hopefully).
