3D acceleration testings

[Joel CARNAT]

Hi,

I'm trying to understand if NetBSD (3.0) has video 3D acceleration (on
some video cards) or not. Here's the summary of a few testings I've done :

*** This is a reference "working" workstation ***

AMD Athlon64 3200+ (2Ghz) / 512Mo RAM
nVIDIA GeForce2 MX400 (64Mo)
Linux 2.6.12
Xorg 6.8.2 / nVIDIA drivers 1.0.8178 / 1280x1024x24
GLXGears = 827FPS
XscreenSaver/Atlantis = 35FPS (GL), 35FPS (Color)

*************************************************

AMD Athlon64 3200+ (2Ghz) / 512Mo RAM
nVIDIA GeForce2 MX400 (64Mo)
NetBSD 3.0
XFree86 4.5.0 / nv / 1280x1024x24
GLXgears ~ 300FPS
XscreenSaver/Atlantis = 3FPS (GL), 3FPS (Color)

************************************************

INTEL Celeron id 0x683 (550MHz) / 128Mo RAM
S3 Savage/IX+MV (8Mo)
NetBSD 3.0
XFree86 4.5.0 / SAVAGE 1.1.27 (GLcore, GLX started) / 1024x768x24
GLXGears = 66FPS
XScreenSaver/Atlantis = 1FPS (GL), 1FPS (Color)

************************************************

INTEL Pentium 4 (2GHz) / 512Mo RAM
Intel 82865G Integrated (8Mo)
NetBSD 3.0
XFree86 4.5.0 / i810 1.3.0 (GLcore, GLX started) / 1280x1024x24
GLXGears = 467FPS
XScreenSaver/Atlantis = 2FPS (GL), 2FPS (Color)

************************************************

INTEL Xeon (2GHz) / 1Go RAM
ATI Technologies Radeon 7000/VE (16Mo)
NetBSD 3.0
XFree86 4.5.0 / ati 6.5.12 (GLcore, GLX started) / 1024x768x24,
1024x768x16
GLXGears = 300FPS
XScreenSaver/Atlantis = 5FPS (GL), 5FPS (Color)

************************************************

To sum up, it sucks :-(
If if read NetBSD's XFree86 manpages :
- nv = 2D accel, no 3D
- savage = none specified
- i810 = 3D accel via DRI
- radeon = 2D accel, 3D accel (at least for RV100=Radeon 7000(VE), M6)

So, I'm not surprise with nv test (thanks nVIDIA for closed-source linux
drivers...). Not either for i810 as NetBSD don't have DRI.

Here's where I'm puzzled :
- S3/Savage - are they supposed to be 3D accelerated or not ?
- Radeon - it's written the one I tried is 3D accelerated... So what's
wrong ? does the manpage applies to Linux only ? is xscreensaver/atlantis
not a good test to check for 3D accel ? do I have to use meta-pkg/xorg ?
did I miss anything ?

To end, the underlying question is : is there any video card at all than can
display xscreensaver visuals (GL or 3D ones) correctly (lets says with more
than 30FPS) ?

TIA,
Jo

My laptop has an S3 for which 3D acceleration works on windows (S3
Savage/IX+MV, for which I also saw DRI support for Linux). However, I
didn't try to install DRM to try DRI with it on XFree86 (and I don't
run xorg).

AFAIK all open drivers for Linux 3D accel use DRI.

No, it obviously is, as an actually accelerated setup worked decently.
Xorg doesn't help on my i82855GM laptop or nVidia cards. Also my Millennium
G200s don't do 3D under NetBSD. I've had all of these work well with
either DRI or proprietary drivers under Linux.

Yes, most any card as recent as 2-3 years ago should work, but not under
NetBSD.
