WebStart / Performance test

[Rob Nugent]

Folks,

If anyone is bored enough, I wonder if you'd be good enough to try the following WebStart/performance test and let me know if it runs on your platform. It needs Java 1.5.0 and will run for exactly 2 minutes and then display a final performance figure in FPS. I'd be paticularly interested to see if it runs on Linux/Mac OK or anything with a 'lesser' video card - integrated Intel graphics etc.

( My Linux install suffers from the Web Start bug,
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6195591 so I can't test this )

For reference, I see

Win2000, Athlon 1800+, GeForce FX5200, 78fps

Please don't resize the window if reporting performance numbers.

Here's the URL:

http://abraded.co.uk/jogl/kit2.jnlp

Some of you may recognize this as a port of my old Java3D app from some time back. If it fails to run, I'd appreciate any diagnostics from the WebStart console

Thanks
Rob

Runs perfectly here (WinXP, Java 1.5)...
But I only get 70 fps

Chman - thanks for that.

I've seen my stuff run slower on ATI cards than NVidia before, and never quite worked out why. My figure was with VSYNC off, BTW.

nlmueng,

Thanks - this is the sort of thing I'm trying to find.

I thought I was checking for this as an extension - obviously not though !

Thanks again,
Rob

[princec]

58fps, Gf2Go. Seems about right.

Cas

[Rob Nugent]

nlmueng,

I think I might have fixed this - I was assuming that anything that had vertex_buffer_object also had multi_draw_arrays.

Would you mind trying it again please ?

You should see either :

"Using MultiDrawArrays", or "NOT using MultiDrawArrays" in the java console output with the new version.

Thanks
Rob

[Rob Nugent]

 58fps, Gf2Go. Seems about right.

Cas - many thanks seems pretty good to me too.

nlmueng,

Thanks for trying this again - it leaves me puzzled however.

My code does:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15

if (gl.isExtensionAvailable("GL_EXT_multi_draw_arrays")) {             useMDA = true;             System.out.println("Using MultiDrawArrays"); } else {             useMDA = false;             System.out.println("NOT using MultiDrawArrays"); } ... if (useMDA) {             gl.glMultiDrawArrays(                 gl.GL_TRIANGLE_STRIP,                 tsa.getStripOffsets(),                 stripVertexCounts,                 stripVertexCounts.length); }

You are seeing the *first* 'println' which leaves me baffled as to why the call the glMultiDrawArrays (Which is indeed line 397) is getting this exception given the test for the extension passed.

Can anyone spead any light on this ?

Puzzled,
Rob

[Rob Nugent]

Ahh - maybe the call should be to glMultiDrawArraysEXT

Can you try it now ?

Thanks
Rob

[nlmueng]

It worked,

70.747025fps
P4 3.0
1 GB ram
ATI Radeon 8500

[Rob Nugent]

It worked

Great - thanks for bearing with me on this.

Rob

[princec]

A trick I did was to create a wrapper GL class that delegated calls to the appropriate method depending on the available extensions / GL version. E.g. glDrawRangeElements calls either glDrawRangeElementsEXT or glDrawRangeElements as appropriate. And vice-versa. Saves me from making this kind of slip-up, which otherwise afflicts me often.

Cas

[Rob Nugent]

Cas,

This sounds a nice idea.

(Unfortunately in this particular case, it was my incompetence rather than carelessness that caused this, however your suggestion sounds good)

Demo runs smoothly on an NVidia Quadro FX Go700 (mobile chip) with 67.42 drivers. However, it looks like none of the textures are showing up. The polygons are smoothly shaded in shades of white, gray, and some tan areas for the lawns.

[Rob Nugent]

Ken,

Thanks - I suspect my texture compression code is the most likely suspect - I'll investigate after the holiday.

Thanks again.
Rob

Just ran it at the office to see what it does here. The results are not pretty:
Win2003, P4 2.4GHz, Intel Extreme driver version 6.13.1.3259, 3.1fps

[cyberyoyo]

Hi,
I just ran it with the following config:
-amd Athlon 2600+
-win98
-GeForce4 ti4200

I get 82.557 FPS

It doesn't run fullscreen, only windowed,is that normal?

puf - thanks for that. I understand the poor performance, as the infrastructure wil drop back to naive rendering if VBOs are not available. When you say things were 'not pretty' does this mean that the image quality looked like if was corrupted also, or was it just the speed that was the issue ?

Rob

[Rob Nugent]

It doesn't run fullscreen, only windowed, is that normal?

Yes - personally I don't much like full screen exclusive mode for the applications I'm playing with.

Thanks for the figures,
Rob

[puf]

Rob, I actually meant that the performance was not pretty. The rendering result itself looks ok.

Yesterday I did some further investigation as to why performance would be this bad and found out that on Windows 2003 Server it uses software rendering by default. That probably explain the crappy performance I've been getting.

I switched video rendering to using full hardware acceleration and most apps now perform much better.

With your kit2 app however, I only see the initial frame being rendered. After that the image remains static, even though the status bar keeps getting updated. The figures in the status bar now actually show more reasonable performance (26fps). But it would be nice if I could actually see some of those frames being rendered. :-/

[Rob Nugent]

puf,

Thanks for the update - unfortunately I'm baffled by the lack of anything other than the first frame. The fact that the status bar is getting updated indicates that I'm in my normal rendering loop, and think that I'm rendering frames OK.

Puzzled,
Rob

Ken - I'm hoping that I might have fixed this problem. I was checking GL_ARB_texture_compression but using GL_COMPRESSED_RGB_S3TC_DXT1_EXT. I'm now checking both GL_ARB_texture_compression and GL_EXT_texture_compression_s3tc and hopefully setting the texture internal format appropriately. If you've got time to give this another go, I'd appreciate it.

You should now see a number of printlns on the Java console saying which iformat is being used.

Well, there's a pretty good chance that it is something in my local settings. Running on a server edition of Windows is guaranteed to take you through all kinds of interesting option dialogs before you get you 3d apps working with any kind of frame rate. :-)

Unfortunately still no textures on my Quadro FX Go700. The new printlns report that GL_COMPRESSED_RGB_S3TC_DXT1_EXT compression is being used. The demo runs with textures on my Radeon 9800 (Catalyst version 4.9; I should upgrade) though slowly -- about 10 FPS when all of the geometry (in particular the houses) is in view, though it speeds up considerably if the camera is pointed up at the lights or down at the road.

[Rob Nugent]

Ken,

Thanks for the info. It leaves me puzzled I'm afraid, as I don't understand why your Quadro FX Go700 is behaving differently to my FX5200. I'm now pretty confident in my texture / texture compression code.

I also don't quite understand why things are so slow on your Radeon unless it is the drivers, given that chman reported 70fps on a similar card. I've enabled anisotropic filtering since this figure was reported, but I wouldn't expect that to account for such a difference.

Anyhow, this all just goes to prove that it's non-trivial to write an infrastructure that works well on more than one hardware configuration, which is what the point of starting this thread was, so it's all good information.

Thanks again,
Rob

Ken - I just tried running with Mustang (1.6.0-ea-b16) and get very similar symtoms to those you describe - grey houses, very little colour except in the lawns. My previous Mustang build was OK.

I've been running with 1.5.0-b64 which is OK - I'm about to try 1.5.0 update 1 - maybe that's what's causing it.
