Re: [JAVA2D] nvidia drivers -> pci express running at x1 instead of 16x
Hi Dmitri, I suppose that the problem with the new drivers (if confirmed) affects the way pixels are displayed onscreen. It should have little or nothing to do with opengl itself, but it could heavily affect the repaint speed of java (-65% in my case). I'll investigate further on the problem. I'll try to prepare a twin machine with new drivers and do some test. The test itself should be very simple: create an int argb BufferedImage (a 640x480 array based image, not volatile, not accelerated) and paint it onscreen as fast as you can while measuring the fps. From a more "hardware" point of view, the PCI-Express x1, x16 issue is quite surely an NVidia winxp driver problem. My suggestion is to always check the speed of the board by first taking a look at the NVidia control panel System information, (bottom left in the control panel window).

Re: [JAVA2D] nvidia drivers -> pci express running at x1 instead of 16x
A little followup: after testing new and beta drivers with no luck, I decided to install a different board: NV7600GT without changing the drivers. The NV7600GT worked very well at x16 speed and the new drivers (169.21) were ok. I removed the NV7600 and installed the NV8600GTX and this time was running at 16x as expected. All ok ? Not completely: the drivers 169.21 for sure give different onscreeen performance, comparing with the previous 163.75. They are roughly 65% slower. Anyway I achieve the same speed when testing in-memory read-write benchmarks: 1.7GB/s write, 1.0GB/s read. For onscreen I mean -> compute some graphics (with opengl), make an argb bufferedimage, paint onscreen (jpanel). My guess is that Nvidia changed something in the "screen updating" code. This is jdk independent: jdk 1.5.x and jdk 1.6.0_04 give the same results.
