  • NVIDIA's 256.25 Beta Linux Driver Slows Things Down?

    Phoronix: NVIDIA's 256.25 Beta Linux Driver Slows Things Down?

    Last week NVIDIA released their first 256.xx proprietary beta Linux display driver that brought many VDPAU improvements, installer improvements, support for new GLX extensions, various bug-fixes, and other enhancements. However, some user reports have shown the 256.xx driver is actually slower than NVIDIA's current pre-200.xx series drivers and so we have carried out a set of tests to see what things are looking like from within our labs. Our preliminary tests do indeed illustrate a drop in performance when upgrading to this new driver.

    Yikes! That's a really big difference. I had been contemplating upgrading to the new beta driver, but I think I'll hold off for now.

    As you said, hopefully the next beta will smooth away some of those rough edges.

      At least they don't fry your video card...

        *chuckle* I'm not sure about that. My 8600GT card/fan makes an interesting noise with the new driver.

        How's the GT240 fare? Has it's performance issue under Linux been resolved with either the 195 or the 256 series?

          I suppose they saw the gaming results between Ubuntu and windows and decided to "fix" the things a bit...

            Maybe those are some sort of PowerMizer issues on the laptop?

              A good strategy to promote/peddle new power hungry and hell hot GTX 4XX GPUs.

                I suspect this is the case, benching the same tests last week a GTX 275 and 8800GT the new driver actually gave a bit of a boost in performance.

                  I've not been too happy with nvidia drivers lately. The new control panel features are nice though. I'm just experiencing many bugs in Starcraft 2 and my mate who has ATi is not experiencing any of the bugs I'm getting. =S ~major sigh~
