NVIDIA 169.04 Driver Improvements
Phoronix: NVIDIA 169.04 Driver Improvements
Last week NVIDIA introduced the 169.04 Beta Linux driver for their GeForce and Quadro graphics cards. This X.Org driver contained a number of GeForce 8 fixes, initial support for the GeForce 8800GT graphics card, monitoring of PowerMizer state information, and other changes. What we had not tested, however, at that time was a performance comparison of the new driver and the previous 100.14.23 driver. The undocumented fact we have found is that this 169.04 Beta driver does deliver performance improvements for the GeForce 8 series on Linux.
The most cool feature of this release is XRender improvement. Speed up is very very much visible in render_bench application. In some tests it is up to 128x speed increase on Geforce 6150. I feel that since 169.04 work in KDE 2D desktop is much more comfortable.
169.04 is the best driver since release when XvMC was introduced.
The sad thing about Phoronix and all other IT news site or newspapers are 3D tests only. I would like to see some day feature review of GPUs in terms of video and 2D performance/features.
(XRender; XAA; EXA; Xv max resolution , image formats; XvMC accelerated movie formats; DPMS)
It would be interesting if recent 169.04 Nvidia driven hardware is faster in 2D than Matrox Parhelia with recent mtx driver, Radeon with recent fglrx driver, S3 chrome 20 with recently released Linux driver (it is initial release but with XvMC !!!) or Intel.
There are test tools for 2D:
render_bench (XRender performance)
xvinfo to check what Xv caps are
xvmcinfo app to check XvMC caps
xvinfo says maximum size is 2046 x 2046

I think we can thank ATI for these recent improvements
I am not so sure about that...

do you know if it can handle more on a card supporting dual-link dvi? otherwise it kindof sucks.
Does the video card adaptively decide when I needs to go on a higher performance level? Because I couldn't find an option to set it.
