繼 3 月份 NVIDIA 的顯卡驅動 5 連發之后，今天 NVIDIA 又推出了***款 185 系列 185.19 Beta 驅動，在添加了一系列新特性的同時，還修正了大量 bug。

其中有兩個重要特性與用戶密碼相關：

 1. VDPAU 視頻加速特性可以利用顯卡的 turbocache 功能所劃分的系統內存了，但暫時僅限集成顯卡，如 mcp 系列。
 2. 支持小于 32x32 的 pixmaps 直接緩存到顯存中，該特性將顯著提高 Firefox 等軟件的拖動時的性能，且在 NV News 論壇上得到了用戶的證實。

以下為該版本驅動的更改日志，供參考：

    * Added support for the following new GPUs:
          o Quadro FX 3800
          o Quadro FX 1800
          o Quadro FX 380
          o Quadro FX 580
          o GeForce GTS 250
          o GeForce GT 140
          o GeForce GT 130
          o GeForce 9600 GSO 512
    * Fixed SDI presentation time queries returning unexpected values.
    * Removed the 'AllowDFPStereo' X config file option, which is now enabled by default.
    * Fixed a bug that caused certain programs to hang when multiple threads call functions in libdl at the same time.
    * Fixed a driver crash when OpenGL applications use an extremely large number of textures.
    * Text rendering to PseudoColor windows with the glyph cache enabled no longer causes GPU errors.
    * The X driver now allows pixmaps smaller than 32x32 pixels to be placed in video memory.
    * Fix a problem that prevented the driver from retraining a DisplayPort link after a device is hotplugged.
    * nvidia-bug-report.sh now automatically gzips the resulting log file.
    * Fix VDPAU to eliminate some cases of GPU hangs when decoding H.264 video on G84, G86, G92, G94, G96, or GT200 GPUs, and supplying a DPB missing some reference frames.
    * The VDPAU presentation queue now syncs to VBLANK in the blit path. The environment variable VDPAUNVIDIASYNCDISPLAYDEVICE selects which display to sync to when TwinView is enabled; see the README for details.
    * On systems using integrated graphics, VDPAU now uses system RAM instead of video RAM for many purposes. This should prevent "out of resources" problems in most cases, even when the video RAM carve-out is configured as low as 128M.
    * Added support for Quad-Buffered Stereo in the main plane simultaneously with the Color Index Overlay; i.e., both Stereo GLX FBConfigs and Color Index Overlay FBConfigs can be advertised and used at the same time, though no single GLX FBConfig contains both Stereo and Overlay capabilities.
