They went official today.



Version: 185.18.14
Operating System: Linux
Release Date: June 05, 2009

Release Highlights

  • Improved compatibility with recent Linux kernels.
  • Fixed a Xinerama drawable resource management problem that can cause GLXBadDrawable errors in certain cases, such as when Wine applications are run.
  • Fixed XineramaQueryScreens to return 0 screens instead of 1 screen with the geometry of screen 0 when XineramaIsActive returns false. This conforms to the Xinerama manual page and fixes an interaction problem with Compiz when there is more than one X screen.
  • Moved kernel module loading earlier in the X driver's initialization, to facilitate more graceful fallbacks if the kernel module cannot be loaded. Removed the LoadKernelModule X configuration option.
  • Added support for new horizontal interlaced and checkerboard passive stereo modes.
  • Fixed an OpenGL driver crash while running Bibble 5.
  • Fixed a DisplayPort interaction problem with power management suspend/resume events.
  • Fixed occasional X driver memory management performance problems when a composite manager is running.
  • Fixed a bug with VT-switching or mode-switching while using Compiz; the bug could lead to a corrupted desktop (e.g., a white screen) or in the worst case an X server crash.
  • Fixed a bug that could cause GPU errors in some cases while driving Quadro SDI products.
  • Fixed a several second hang when VT-switching while OpenGL stereo applications were running on pre-G80 Quadro GPUs.
  • Added support for multiple swap group members on G80 and later Quadro GPUs.
  • Fixed the behavior of the NV_CTRL_FRAMELOCK_SYNC_DELAY NV-CONTROL attribute on Quadro G-Sync II.
  • Fixed a problem with Quadro SDI where transitioning from "clone mode" to "OpenGL mode" would fail.
  • Fixed VDPAU to eliminate some cases of corruption when decoding H.264 video containing field-coded reference frames on G84, G86, G92, G94, G96, or GT200 GPUs. Such streams are commonly found in DVB broadcasts.
  • Slightly improved the performance of the VDPAU noise reduction algorithm.
  • Enhanced VDPAU to validate whether overlay usage is supported by the current hardware configuration, and to automatically fall back to the blit-based presentation queue if required.
  • Fixed error checking in VdpVideoMixerRender, to reject calls that specify more layers than the VdpMixer was created with.
  • Modified VDPAU's VDPAU_DEBUG code to emit a complete backtrace on all platforms, not just on 32-bit Linux.
  • Improved interaction between VDPAU and PowerMizer; appropriate performance levels should now be chosen for video playback of all standard resolutions on all supported GPUs.
  • Fixed a bug in VDPAU that sometimes caused "display preemption" when the VdpDecoderCreate function failed.
  • Fixed a potential segfault in the VDPAU trace library, triggered by a multi-threaded application creating a new VdpDevice in one thread, at the same time that another thread detected "display preemption".
