Title:
Major OpenGL performance degradation over time
To
With the new 304.43 drivers, the issues are still there. Glxgears now
reports that it runs in sync with the monitor refresh rate (60FPS).
This issue is driving me nuts! Nouveau is also not a proper option for
me, since the whole desktop experience looks seriously stretched. The
only work around I
I finally found some time to test some other drivers. With NVIDIA 295.49
drivers the same "drop in performance" issues appear.
When running Nouveau, the issues are gone. Glxgears reports around 650
FPS with Nouveau.
With nouveau the desktop looks streched, but I have not looked into that
further
Interestingly, I notice the following behavior in gnome classic without effects
(gnome-fallback):
Glxgears always gives me around 26000 to 29000 FPS. However, response of the
GUI is sluggish some while after login. E.g. while typing this message, letters
lag behind, appearing on screen in bursts
I can confirm that the bug is also present in an older version of the
nvidia-graphics-drivers, since I have used an older version in the past.
I am pretty sure it was 295.40. I was hoping that the 302 drivers would
have fixed it, but obviously they don't. I will try the nouveau drivers
at a later m
