Description Ravi Srinivasan 2009-06-10 03:34:16 EDT
Description of problem:
I was feeling very adventurous so I got the latest 2.6.30 rc from koji and installed it on my brand new f11 setup. I used glxgears as a high level video performance indicator and then use some avi videos and youtube for comparison

This is a thinkpad R61 with intel GM965 and Core 2. running F11 64-bit GNOME.

700 FPS with 2.6.29-4 (the one that came with F11 stock - .167.f11?)
200 FPS with 2.6.30-0.100.rc8.git6.fc12.x86_64!!

[ravis@tenken ~]$ glxgears
1381 frames in 5.0 seconds = 275.892 FPS
1266 frames in 5.0 seconds = 253.128 FPS

FYI - I ran a Debian 5 livecd and it can push 1000+ FPS. but we all know how the intel driver is borked for the time being and will take time to stabilize...here's hoping they fix it soon. Fedora's patched kernels should not add on the already existing poor performance - just my 2c

abysmal video performance. stuttering, stalling and unusable 

BTW - should i be even reporting koji build bugs here??

Version-Release number of selected component (if applicable):



How reproducible:

Get latest 2.6.30 rc from koji. install and watch videos/youtube/3D apps

Steps to Reproduce:
Actual results:
poor video and 3d performance. I am assuming kernel caused the regression since the intel video driver version is the same as in the old version. all other versions remain the same from F11 stock

Expected results:

improved or equal performance as in F11 stock or older releases

upgraded to kernel-PAE-devel-

The video performance is very bad.  Made my eyes bleed.

Comment 2 Vedran Miletić 2009-10-26 11:02:26 EDT
Brian, this is not the same issue as original report. Please complain to NVIDIA about issues with their proprietary drivers since Fedora can't address them. If you used nouveau, that would be another situation.

Ravi, how about _complete_ Fedora 12 Beta (you can try with LiveCD)?
Comment 3 Brian Millett 2009-10-26 11:30:41 EDT
Ok, thought as much.

They fixed it in the 190.42 release.  I just thought that since the nouveau & nvidia drivers showed the same problem at the same time that there might be a related issue.  I do not believe in coincidences.
Comment 5 Vedran Miletić 2009-11-05 17:57:51 EST
This has been fixed in current post-Fedora 12 Beta rawhide packages.

Intel driver is actually working quite nice now.
