Slow OpenGL performance in Ubuntu 18.04 with RTX2080.

Graphics / Linux Linux

Hello,

We have a problem with OpenGL applications (built on top OpenSceneGraph), on Ubuntu 18.04.

Driver tested: 440.44 manually installed from NVidia binaries and “ubuntu suggested” 435 (proprietary, tested). We have the same behaviour in both cases.

We have a GTX1080Ti and our test application run at 200fps. glxgears test run at 22500fps.

Now, we are using the new RTX2080 (on the same machine we have changed the graphics card only), but we see poor performances: our application run at 130fps (instead of 200fps) and glxgears test run at 4000fps (this is really weird!).

There is something to setup in order to exploit OpenGL performances?

Many thanks.

Bye, Dario Maggiari BK S.r.l

Hello,

I see no answer but a bunch of visualizations. This does not happens to anyone?

Please post the output of
glxinfo |grep vendor
Furthermore, please create and attach a new nvidia-bug-report.log while your application is running.

Hello,

glxinfo | grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

You find attached the log during running app.

Thanks for your help.

Bye.

GPU utilization is 100%, clocks are at maximum, yet power draw is only 130W at 39°C. Looks like your application is very inefficient on the Turing compared to the Pascal, clogging the pipelines while not doing much. Driver/hardware seems perfectly fine.
