Nvidia Releases OpenGL 4.0 Linux Drivers

,----[ Quote ]
| OpenGL was released just a month days ago. 
| Now, Nvidia has released its latest OpenGL 
| Linux driver with full support for OpenGl 
| 4.0 on GeForce GTX 480/470. In addition to 
| this, Nvidia has also release four new 
| OpenGL extensions which provides additional 
| capabilities to developers.


The Real Need For Nouveau Power Management


Nouveau Is Power Hungry On Desktops Too

,----[ Quote ]
| This morning we talked about the real need 
| for Nouveau power management as with a 
| notebook bearing a NVIDIA GPU this open-
| source NVIDIA driver can easily consume 
| 10~30% more power than using NVIDIA's 
| official binary driver. While power 
| management is more important on the mobile 
| side, a quick test was carried out on a 
| desktop too.
| For this Nouveau desktop testing of the 
| power consumption a AMD Sempron box was 
| used running a NVIDIA GeForce 9800GTX. 
| Ubuntu 10.04 LTS was used comparing its 
| Nouveau KMS driver (using the Linux 2.6.32 
| kernel but with the 2.6.33 DRM back-ported, 
| and no Gallium3D driver in use) to the 
| NVIDIA 195.36.15 binary driver. Ubuntu 
| 10.04 was used for some variation in the 
| test results and the Red Hat Anaconda 
| installer with Fedora 13 Beta would hang 
| with this AMD system when it came to 
| detecting the Serial ATA hard drive. 



Nouveau Now Switched On In Ubuntu 10.04

,----[ Quote ]
| For those interested in proper OpenGL support for
| gaming or other situations, the NVIDIA binary
| driver can still be installed in Ubuntu 10.04.


Benchmarks Of Nouveau's Gallium3D OpenGL Driver

,----[ Quote ]
| To benchmark the Gallium3D driver in Fedora
| 13 for Nouveau we fired up the Phoronix
| Test Suite and ran the OpenArena, World of
| Padman, Urban Terror, Unreal Tournament
| 2004, and Warsow test profiles. We tested
| each of these OpenGL games at five
| different resolutions: 800 x 600, 1024 x
| 768, 1280 x 1024, 1680 x 1050, and 1920 x
| 1080.


A Nouveau 3D Driver That Works For Old NVIDIA Hardware

,----[ Quote ]
| This afternoon, however, a new Mesa DRI
| driver has emerged for Nouveau that
| provides working 3D support for older
| NVIDIA hardware.

Version: GnuPG v1.4.9 (GNU/Linux)
