I have an application that needs to create a 4640x1050 pixel OpenGL window. This works on XP32 and XP64. However, in the Vista 64-bit driver, I cannot get a window over 4096 pixels. If I create the window at 4096 pixels, I get the image. If I bump it to 4097, it just stays blank. I have the 182.65_quadro_winvista_64bit_english_whql currently installed, but this has been true for several driver versions now - I have just stayed with XP for my project. I know the hardware limit was raised to 8K a few generations back, maybe this piece has not been tested on Vista64 ?

I think you might need to contact Nvidia directly, or at least the official Nvidia forums, on this one. I'm not sure that the demographic that frequents this site will be familiar enough with your needs to address this question. Good luck, and if you find your answer elsewhere please share with us here.
