[mythtv-users] very low glxgears fps

I am completely puzzled by all these posts and am
running out of ideas. FYI, 'cat
/proc/driver/nvidia/agp/status' on my laptop returns
AGP Rate: 4x
Fast Writes: Disabled
So no fast writes, no SBA (whatever it is).
glxgears with X running at 16bot color depth returns
22247 frames in 5.0 seconds = 4449.372 FPS
22455 frames in 5.0 seconds = 4490.754 FPS
21735 frames in 5.0 seconds = 4346.865 FPS
I have installed the nvidia driver from a .run file
picked on the nVidia website. My laptop is sort of old
now, 1.6 GHz pentium M, GeForce 4200 Go.
I also have this, if of any interest :
Model: GeForce4 4200 Go
Video BIOS: 04.28.20.31.c1
Card Type: AGP
DMA Size: 32 bits
DMA Mask: 0xffffffff
NVRM version: NVIDIA Linux x86 Kernel Module 1.0-9631
Thu Nov 9 17:38:10 PST 2006
GCC version: gcc version 4.1.2 20061028 (prerelease)
Sorry not to be of more help. Maybe you could install
a small debian partition for a try. If you have 3G of
free space on your HD (you could also do with 1.5G),
it would be interesting to do so. It is very easy to
install debian. Pick the debian-installer for the
'testing' version, the 20MB business-card.iso and let
the installation proceed, provided that you have an
internet connection and a DHCP server at home. I
always carry with me a USB key with all that debian
installer stuff, and can install linux on some
friend's computer if their BIOS supports USB boot.
Anyway, this is what I would do out of desperation. It
would take you about 2 hours if you don't install the
whole Desktop software packages but only the standard
system + X + say openbox for a light weight windows
manager (remember, it's just a test).
