You have ~750fps with glxgears - wow! I only got ~650fps but then I'm
running a 1600x1200 rather than 1280x1024 display. I think the issue
is memory bandwidth - glxgears is a test of memory bandwidth more than
anything else - there is no fancy shading so all of that DX9 hardware
counts for naught.

FX 5200 cards come in two flavors 64bit and 128bit memory bus and I'm
sure I have the 64bit version (notice how card manufacturers are keen
to list tons of mostly meaningless trademarked buzzwords on the box
but are less keen to list important things like GPU clock and memory
bus width and clock...) - to be fair Gainward did have the word "lite"
on the box.

With so little memory bandwidth and a 1600x1200 display sucking a
large chunk of it, 650fps is not so surprising. I tried an FX 5600
card and got ~2350fps so I'll be returning the FX 5200.

Probably a obvious/stupid question for you but.. how do you measure FPS ? I've heard that some people use gl gears, but do I have to launch it from the command line ?

I tried the screen saver an I got 100 fps at most, what's wrong ? I have the latest drivers and a gf4 MX 4000 that number should be higher right ?

The command is "glxgears" - you type it into an xterm. It opens an
opengl window of a standard size with 3 rotating gears and prints out
framerate information to the xterm.

Screensavers occupy the whole screen and so would be substantially
slower than the standard size glxgears window. Depending on the actual
screensaver it may or may not use 3D acceleration.

humm, awful , only 350fps, is that normal for a GF4 MX 4000 ? I have an Athlon 2000 in 1024x768x32 mode. (I'm running many other programs I can't close now, I'll try again later with fewer processes)

my other PC have a Radeon 9200se with an Athlon Thunderbird 1300 and I got 664fps

one thing makes me wonder: it doesn't matter wether agpgart & intel_agp are loaded or not, it's still the same results. according to a friendly guy at #nvidia@freenode, this may be due to the fact that glxgears is also quite cpu-intensive but doesn't produce much data (which would explain agpgarts lack of impact on performence).

maybe we should consider doing some real benchmarks (ut2003/04, q3).

any suggestions ideas?

Talking Outstanding numbers on the 2.6 kernel!

I'm using a FX5200 on a 3 GHz P4, Linux kernel 2.6.3, XFree86 4.3.0-55, on Fedora Core 1.

Using the original nv driver, glxgears produced only 375 fps.

Using the 5336 driver, it's now running at 1230 fps.

Way to go Nvidia!

FX5200 T128, Athlon XP1800+, 256 Mb RAM, using the latest drivers on Mdk 9.2 (Kernel 2.4.22-28mdk), I get 1100+ fps with glxgears, in 1024*768*24. I tried nvagp and agpgart and both give about the same result.

Default Re: performance issues / fx5200

I don't understand why I get so low fps (340 average), my PC has XP2000+ , although I have a MX 4000 with AGP 8X enabled, I've been told that the MX 4000 isn't much slower than the FX 5200, what could be wrong ?
is there any parameter that I can add to my XF86config to make it faster?
