3D issues with Athlon X2, x64, 6600LE, and dual monitors
Two development workstations at my company show the same symptoms.
They are configured as follows: Windows XP x64 Edition Athlon X2 3800+ ABIT AN8 (nForce4 Ultra) motherboard Albatron 6600LE 256MB PCIe video card 1x hp pavilion f1903 LCD monitor on DVI-D 1x Samsung Syncmaster 955DF CRT monitor on VGA 84.21 WHQL ForceWare driver Running in DualView mode Often times the display stutters when in accelerated mode, by which I mean objects will move forward, then backward, then forward again quickly. It's easily noticeable in the OpenGL screensavers included in Windows. It also affects transition effects in Picasa. I suspect it may be a bug in the x64 driver since none of our users with 32-bit XP have complained about the problem. Also, if 4x AA + 8x AF is turned on in the video driver, running any of the built-in OpenGL screen savers will instantly hard-lock the PC. But disabling one monitor seems to circumvent that problem. Are there any known issues with dual monitors on dual-core X64 systems? Do I perhaps have a pair of bad Albatron video cards? |
