Thumbs down Performance drop in 44.96

I've noticed a performance drop on all the machines where I tested the new drivers. It's about one half of the previous performance. The test was made with glxgears without vsync enabled. But I notice this on other applications also, although I can't measure the performance loss as well as with glxgears...

The cards tested were two Geforce4 Ti4200, one Geforce 4200 Go and Geforce 2 MX400. All of them have one half of the performance that the previous driver gave.

Am I the only that noticed this? Other people noticing this performance drop?

Default Oh...

Then it's not only me. More people noticing the performance lose? Any hint on when this problem will be fixed?

Note that nvidia isn't making these drivers for us the simple users. They are making this drivers mainly for their big customers that use Quadro like cards.

For past drivers complains were that the drivers were unstable and things like that. Now when the drivers are more stable than in the past, the performance indeed is less than before.

Likely the problems will be fixed a bot in upcoming releases but remember that stability is more important than performance for nvidia and for most users.

Maybe because they are optimizing for FX cards they broke something for Geforce2. i ahve an FX card and I instead got some more performance in Quake ]I[ for 1024x768.

I also noticed a big performance drop after upgrading to the latest drivers. This was with the 2.4.21 kernel. For some reason agp was disabled and I was no longer able to load agpgart, even after recompiling everything. After upgrading to 2.4.22-pre7 (at the time) everything seemed to work fine again.

I noticed a slight drop of fps in Quake 3 with the new drivers, but nothing as dramatic as 50%!!

43.63 = Timedemo (1024x32) 175 fps
44.96 = Timedemo (1024x32) 170 fps

UT2003 runs more 'consistently' (no sudden drops in frames).

Athlon XP 2000+
RedHat 9 (kernel 2.4.20)
GeForce 4 Ti 4600
VIA KT266A chipset.
512 MB DDR (266Mhz)

I've noticed that X's CPU usage in 3D apps with the latest drivers is
about twice as high as compared with 1.0-4363. Used to be 2-6%, now it's
8-14%. Consequently I'm getting lower framerates, for example in Q3
demo. That's why I/ve reverted to 4363. My video card is
FX5200 250/250, btw.
