    Phoronix: NVIDIA 256.53 Stable Linux Driver Release

    Over the weekend there was a new Linux binary driver release from NVIDIA that was the 256.52 driver in a pre-release state. It didn't deliver on OpenCL 1.1, Fermi Linux overclocking support, or any other radical features, but it did bring a handful of bug-fixes. Today this driver has been released as stable after being branded the NVIDIA 256.53 driver...

    Why did the version change if there is no real difference?

      Just got my twin Palit GTX465 up and running. I've been testing Linux SLI performance with the lastest 256.53 drivers. Soo far I've found that SFR works the best but it bearly performs better then a single card...

      MinFPS - 35.9 - 46.8 - 47.5
      HighFPS - 55.1 - 79.8 - 82.2

      SLImode - AFR - OFF - SFR

      Score - 558 - 784 - 855


      On a side note... Sanctuary had some weird green discoloration issues when the demo was started with PTS. When I start up the demo by itself I don't see this problem.

        Could you compare that with Win + OpenGL 4 / DX11?

          Yes, I can get on that

              There must be something wrong with your Linux install. The single gpu values are too different. Maybe use kernel 2.6.35 - that would be needed for X6, no idea what is slowing down your system... Maybe SLI works better with high performance Intel CPUs on X58. AMD CPU on NV chipset does not seem to work well - at least not with your system...

                I'm already running 2.6.35-18-desktop kernel from the opensuse build service. I'm running a quad core not a x6 anyways.

                I'm pretty sure you ment windows anyways...

                Also i fudged up those #. on the Windows dx11/OpenGL sides(long night) i typed down the tess-off results instead of tess-extreme...

                -Win7 OpenGl-

                  The opengl auto score is still wrong or? Maybe upload all hmtl files onto your homepage. The results can not be correct that you posted here.

                    Yea looks like I posted tess normal results for Win7 OpenGL. Seems like I can't get anything right this week and now I'm just looking like a damn fool... I'm just going to rebenchmark and save the results which I only wrote down on a piece of paper last time. Sorry for my incompetence

                      Why is Anisotropy 16x for Win7 but disabled for Linux?

                        I noticed that when i was uploading them to the web... I forgot to set it in the .sh script. No little program like in windows to adjust the settings before you start the program. Unless I'm overlooking it.


                        I wasn't trying to compare windows this time anyways... I just wanted to point out SLI support for Linux needs some much needed work... AFR causes performance issues and SRF works but the performance is about the same as a single card.

                        I'll retest/reload the Linux results for Anisotropy 16x. Thank God I'm not Michael

                          I took the liberty of posting those results on the NVnews forums and hope this will further open their eyes to improve performance quickly. You can find the post here: http://www.nvnews.net/vbulletin/show...=153283&page=2

                          Please, always post such benchmarks and problems on NVnews forums. The driver devs also take a look at them, they are the only people who can make things change. The more people they encounter with such problems, the more pressure we can execute.

                            Sleep is still broken on my 9500GS. The system consistently deadlocks shortly after exiting sleep mode (Ubuntu 10.04 amd64). It used to work correctly on a X1950/radeon but haven't been able to make it work since I installed the nvidia card. Bah.
