Default Re: Nvidia 27x.x and 280.x series: OpenGL performance regression

I uploaded your blender files to my site: http://liquorix.net/misc/nvidia/

Xhondal, can you confirm these are your original files so that nvidia can download them?

Here are the md5sums:
Code:
7d01508a67d8dbcb3a612b299c2379db  opengl.blend
9c9dc1063c071bd2c7df2836961ed9b3  opengl.7z

I have approx. 50% frame rate in games with 275.21 compared to 256.53.

Default Re: Nvidia 27x.x and 280.x series: OpenGL performance regression

I was wondering how many times and how many people have to write here about the regression of the drivers performance and when we can expect some SOLUTION?

EDIT: No difference between 270.41.19 and 280.11 for the MD CUDA applications AMBER 11, ACEMD and so on..In Heaven 2.1 bench the result is the same too. I will re-post my previous text here

tested on 9500GT and 7900GS, performance for me are more or less the same, if not better on 275.x compared to 260.

Hi KDE, what card are you running on your system?

@ kokoko3k and kometata:
thanks guys, would you mind to perform test with Blender and the scene uploaded too, as described in post #11?

7300 GT
I have same results from glxgears, Unigine benchmarks, but games are randomly affected. Game which always has average 120 fps with 256.53, sometimes has only average 40 fps with 275.21. Other games have sometimes completely corrupted graphics.

NVIDIA is tracking this issue under internal bug ID 851266. We are able to reproduce the performance regression using the provided Blender model on both GNU/Linux and Windows 7.

It seems the issue is still present in recent 285.05.09, under same conditions (blender and scene provided) fps are the same as 280.x series

Default Re: Nvidia 27x.x and 280.x series: OpenGL performance regression

Have there been any updates with the OpenGL Performance? Our application is unable to use any drivers newer than 260.x due to frame over runs from the newer drivers (stutter). The 290.06 beta driver shows the same issues.

The stutter is on both the GTX480 and 580 cards both Ubuntu 10.04 64 and RHEL 5.4 64
