Default Low fps with 5336

Hello,
I have a problem with the newest release.
My system:
AMD Athlon 1800+
GeForce4 MX440
Linux 2.4.24
Driver version 5336
NvAGP = 1

With the new release (and also with 5328) I only get 160 fps when running glxgears. With 4496 I got 1800!

Has anybody an idea why this happens?

Regards Gerhard

I don't know for sure, but I saw the same thing with 5328 (I haven't tried 5336 yet).

Normal games work the same as they always did, though. So I wrote it off to the fact that glxgears is too simple (and therefore too processor-intensive) to be a graphics card benchmark. Plus there are the changes to kernel 2.6 that improve responsiveness (possibly at the expense of background processes), and there's the change in driver 5328 that "reduces CPU usage when a program is syncing to vblank" which that may have some relevance, too.

160Hz isn't by chance your video refresh rate is it?

Mine was stopping at about 100fps, and my refresh rate was 75Hz.

With 5336, I get the 100fps behavior most of the time. But once in a while, it really speeds up (like up to ~2000fps, which is much closer to normal). I can't figure out what I do that makes it do that, but I do notice that when it's running at 100fps, the CPU usage is close to zero. When it decides it wants to speed up, CPU usage jumps to around 95-100%.

Doesn't bother me, though -- like I said, games work fine.

Question

I've got the same on:

P4 - 2Ghz
512Mo
GeForce4 MX 440 with AGP8X
linux 2.4.25

Using DUAL screen (not twinview)

With 4496 drivers glxgears it's about 1800~2000fps
With 5328,5332,5336 it's about 160~400fps

The game like Quake3 and ut(2003/2004) work fine, but the all opengl things like wine are very very very slow
I would like to upgrade because there is some display bug, with GLscreensaver, UT ...

Is the trouble is solve with a 2.6.4 kernel and 5336 drivers ?
Should I buy a new card ?
Should I return to Micro$oft ?

This isn't the best test of fps anyways. It fluctuates a lot. (try opening a program like open office while its running... mine shoots up to 20,000 fps) I get close to 10,000 normaly... but then again I do have a fx 5900.
Quake 3, while a bit outdated, is a better test of raw speed, and you can get more constant values.

I don't know if it's the bettre test, but with new drivers, all glx are slow ...
- wine with ultraHle (unplayable with new new driver)
- xmms Glplugins
...

I just want to know why the new drivers didn't work fine, and how can I solve it.

I dont use the 5336(4620 dont compile with my 2.6.4) as it is consideribily slower, why dont you just use the 4620 instead of making a issue out of it.

Agreed. I use 4620s and its gonna take a lot to convince me to switch.... they are beta drivers and still better than the official ones, go figure.
