Serious perfromance regression after upgrade from 295.33 to 295.40 with GF 7050 PV

[baryluk]

Hello,

I reported this bug to Debian BTS, http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=668854

I have, GeForce 7050 PV (integrated card nForce 630a), and running i386 with kernel 3.2.0.

Basically 295.33 drivers works without problems, but 295.40 shows drastic performance regression. glxgears go from 1400 fps to 5 fps, and Counter-Strike 1.6 under wine from 50 fps to 0.5 fps.

I also tested 295.33 with security patch: ftp://download.nvidia.com/XFree86/pa...g-290-295.diff , and it doesn't show any problems. This indicate that other changes between 295.33 and .40 created this regression.

nvidia-bug-report.log (when running 295.33 + patch) attached.

Ah, sorry attached log is from 295.33 + security patch. I will resend new log, after reboot.

I have the same problem with Open GL applications after upgrading from 295.33 to 295.40.
I'm running ArchLinux x86_64 with 3.3.2 kernel and I have a motherboard with Nvidia GeForce 6100 integrated video controler.

Hi,

I added

	Option "NoFlip" "true"

to xorg.conf, and it is in effect according to Xorg.0.log

...
[136552.492] (**) NVIDIA(0): Option "NoFlip" "true"
[136552.492] (**) NVIDIA(0): Option "RandRRotation" "true"
[136552.492] (**) NVIDIA(0): OpenGL flipping disabled
...

but performance is still poor (4.5 fps in glxgears compared to 1500+ with 295.33).

Hm. No issues on Debian 32-bit / nvidia 8200 integrated card.

[Plagman]

We've identified a performance problem with integrated graphics chipsets that got included in the 295.40 release, but is independent of the security fix. Expect a fix shortly.

I tested 295.40 on amd64 with Geforce 7 series card (7600 GT, discrete card on PCI Express), also on Debian sid, and I do not expirience this regression. So indeed probably this is releated to only integrated gpus.

My 8200 is integrated (on ASUS M3N78-VM mobo). And it works just as before.
