The increase in 87.56 is only marginal here:
Code:
####################################################
# Performance Test. Your system scores...
####################################################
# FRAME COUNT: 231 frames
# TIME:        20.039 seconds
# AVERAGE FPS: 11.528 fps
####################################################
# Your system Evas Benchmark:

# EVAS BENCH: 0.192

####################################################
The previous result was 0.179. For comparison, my notebook with integrated i945 video (i810 driver) scores 0.304 in that test.

By the way, when the test is running, apparently some operations complete much faster than the other, so the objects in the window sometimes accelerate, but most of the time they move slowly enough.

I'm attaching another bug report for your consideration.

according to the render-bench scores (from above, and with the latest driver), the only xrender op that is actually accelerated is non-scaled over blends.

I'm not sure of what exactly accelerated by the open-source radeon drivers, but r100/r200 series cards achieve almost the exact same performance with the xrender evas engine that they do with the opengl evas engine .. I don't know of any reason that nvidia can't achieve the same...

netllama, have you had time to look into this yet? Or any idea of when to expect an improvement?

Thanks,
Ben.

Personally I would take the bench from rasterman with grain of salt. Remember that he's making a "competing" library to the Render extension AFAIK. Perhaps it would be an idea to test the render test with RenderAccel off and on.

Also if you notice that when it's doing the imlib tests it's not drawing anything on the screen.

I just did a test using renderbench with both RenderAccell off and on. No difference what so ever on the results.

Edit:
Ok, I was using Xgl on all the above tests which probably weren't a good idea. Anyway did some other tests with gtkperf.

With RenderAccel = true :

Both tests were done with starting X with "xinit -e xterm" as root, so no other application was interfering.
The thing about gtkperf is that it's more a "real-life" benchmark, since it actually using the gtk library to render everything.

Another test with the same xinit setup and using firefox :
http://librarian.launchpad.net/1585880/test.html
Did the scrolling with text test :
With RenderAccel = true : 10.9 sec
With RenderAccel = false : 27.0 sec
Using Xgl/compiz(and full gnome loaded) : 22.4 sec

The div test :
With RenderAccel = true : 7.6 sec
With RenderAccel = false : 8.2 sec
Using Xgl/compiz(and full gnome loaded) : 11.6 sec

It's definatelly accelerated

Yes, RENDER is definitely being accelerated. But, not much of it.

The problem is not that imlib2 is faster, but that the radeon driver on r2xx cards (not ATI's) apparently does many of the other RENDER ops a lot faster than my 6800GT can. I can't provide numbers as I don't have the hardware.

*edit* And yes, RENDER tests on Xgl shouldn't be affected by RenderAccel at all. I was under the impression that it was always rendered with OpenGL

Only the window mapping is done with OpenGL AFAIK. It's the same when the renderbench is doing offscreen Render tests.

Anyway, although not all things are accelerated in Render text rendering seems to be, which IMHO is the most important one.

It outperforms the geForce 7800GTX that I have on my desktop in 2D usage

Think about it a bit...

Default Re: hardware accelerated xrender ?

Did you test with the 169 beta driver?

The changelog states "XRender improvements" and some guys reported already many performance improvements - but most reports were only subjective.
It would be great if you could again run render_bench on your 7800GTX with the new beta drivers, to see how close the new dirvers come to your mobility radeon X1600. This would generate useful numbers, instead of vague reports

Thanks, lg Clemens
