Intel Sandy Bridge Linux Graphics? It's A Challenge

[psycho_driver]

Agree, it didn't seem like a valid test. Still wondering where the proper benchmark is. The phoronix test suite documentation link doesn't give a clue.

Out of the open source stuff used for benchmarking within the suite, Warsow is one that I personally think is fun to play. It should be in Redhat's package manager. ~400MB download. Once you start, use ` to bring up a console and type /set cg_showfps 1 (if I'm remembering correctly). You would probably need to go into the advanced graphical settings and raise your max FPS value. To make it easier for us to get an idea of what kind of performance you're getting I would suggest using the predefined quality settings (low, medium, high).

well can we even really advocate using the phoronix test suite until Michael changes the board software to finally allow a longer edit time

we could then come back and edit our posts and add that info and recommendations

(just pulling your leg Michael , but consider that a continually repeated request from several users)


i guess you could give http://unigine.com/products/heaven/ benchmark a try, it says it has Support of DirectX 9, DirectX 10, DirectX 11 and OpenGL 4.0 hardware
and lists a Linux version (233 Mb): download so i assume you will get some form of consistent result at least

Doesn't work. I also tried the recommended workaround of setting the following environment variable: MESA_EXTENSION_OVERRIDE=+GL_ARB_map_buffer_range
but it made no difference.

Warsow bombs out with:

Perhaps you should just wait for the phoronix test results. I'm really only interested in 2D and video rendering myself.

Thanks for trying

Track Mesa 7.11 -devel. If you can successfully run and render Unigine's Heaven and OilRush game on it, I'll be amazed...

Does QuickSync and audio over HDMI work on Linux?

That's more interesting to me for HTPC/MythTV usage than slow 3D graphics off an embedded graphics chip

It's as if nobody is actually trying these things...

hardware accelerated video was tested here:

http://www.phoronix.com/vr.php?view=15756

So the answer is yes, quicksync does work (at least for certain video codecs).

Personally I don't think linux is a great htpc choice since the players can't even navigate a blu-ray, even if one goes to the trouble to strip the DRM first.

Thanks...totally missed that article.
Looks like quicksync for video transcoding will be added eventually:
"Soon it has also been said that Intel will provide VA-API video encoding support for Sandy Bridge hardware too, which will require updating the DRM and VA-API library once more."

Bluray use doesn't matter that much to me yet...I'd prefer having a standalone bluray 3D player since AFAIK, bluray 3D isn't accelerated in low power hardware yet.

Put that in MKV and you are set. One hard drive is worth a pile of bluerays. You can throw your purchased bluerays in trashbin then, collecting only the caselabels as proof for customs or such that you actually purchased them should you travel xross the country with your films.
