The following problems still exist in this release and are in the process of being resolved.
If you are using a laptop please see the "Known Laptop Issues" in Appendix I, Configuring a Laptop.
When FSAA is enabled (the __GL_FSAA_MODE environment variable is set to a value that enables FSAA and a multisample visual is chosen), the rendering may be corrupted when resizing the window.
When a multithreaded OpenGL application exits, it is possible for libGL's DSO finalizer (also known as the destructor, or "_fini") to be called while other threads are executing OpenGL code. The finalizer needs to free resources allocated by libGL. This can cause problems for threads that are still using these resources. Setting the environment variable "__GL_NO_DSO_FINALIZER" to "1" will work around this problem by forcing libGL's finalizer to leave its resources in place. These resources will still be reclaimed by the operating system when the process exits. Note that the finalizer is also executed as part of dlclose(3), so if you have an application that dlopens(3) and dlcloses(3) libGL repeatedly, "__GL_NO_DSO_FINALIZER" will cause libGL to leak resources until the process exits. Using this option can improve stability in some multithreaded applications, including Java3D applications.
XVideo will not work correctly when Composite is enabled. See Appendix Q, The X Composite Extension.
This section describes problems that will not be fixed. Usually, the source of the problem is beyond the control of NVIDIA. Following is the list of problems:
Problems that Will Not Be Fixed
This motherboard uses a LinFinity regulator on the 3.3 V rail that is only rated to 5 A -- less than the AGP specification, which requires 6 A. When diagnostics or applications are running, the temperature of the regulator rises, causing the voltage to the NVIDIA chip to drop as low as 2.2 V. Under these circumstances, the regulator cannot supply the current on the 3.3 V rail that the NVIDIA chip requires.
This problem does not occur when the graphics board has a switching regulator or when an external power supply is connected to the 3.3 V rail.
On Athlon motherboards with the VIA KX133 or 694X chip set, such as the ASUS K7V motherboard, NVIDIA drivers default to AGP 2x mode to work around insufficient drive strength on one of the signals.
AGP 1x transfers are used on Athlon motherboards with the Irongate chipset to work around a problem with signal integrity.
On ALi1541 and ALi1647 chipsets, NVIDIA drivers disable AGP to work around timing issues and signal integrity issues. See Chapter 4, Common Problems for more information on ALi chipsets.
