what's the best performance improvement from 2.2.3 to 2.3?

[Ed]

2.3 is touted to have some big performance improvements in rendering. Just to see if the 10-500% is realistic, why not take some timedemos (suggested demo1 as it's pretty intensive) for 2.2.3 and 2.3 and post the results? The mean result should be used as the min and max are too variable. Settings are arbitary but need to be equivalent across the different versions. Post your graphics card model too so people have some idea what they may get from their hardware.

I've got a 6600GT AGP 128Mb.
2.2.3: 28fps
2.3: 41fps
Giving 46% improvement

Anyone getting +500% I wonder?

stand on a certain map and looking at a certain direction. Then its very possible that its 500-1000% more fps
"tdem demo1" is an other matter me thinks. I get about 50% more fps

Don't expect to get +500% on average... But nevertheless on some maps this is realistic in certain spots. Loof (v1) is pretty much the worst case:


As you can see it's 14fps with 2.2.3 vs. 186fps with 2.3 with the same settings, that's roughly +1200%

Momentary increases in framerate may be enormous but you can't get any very accurate numbers for them and they don't give a good reflection on improvement during normal gameplay, this is what timedemos are for.

I've now done a comparison on a laptop with Dell integrated graphics running the free drivers under Linux. This system is pretty poor for Nexuiz so graphics settings are pretty low. Even so, 2.3 gives a worthwhile performance improvement:

2.2.3: 9.2895218
2.3: 14.3845882
That's a 55% improvement in average framerate.

I also found during testing that this system performed slightly better (statistically significantly) with gl_vbo 0.

Well it just depends on the map.. with demo1 i get 50% more in 2.3. From around 90 to 145fps.. demo5 (when i copy it into 2.2.3) raises from 100 to 200fps so 100%.. the biggest improvement i found in a single spot was in a map from the q3mappack from 35 to 310fps.
And thats at my usual LOW play settings. At normal or higher settings the raise can be move extreme in %

Have the notoriously high-polygon models been fixed? Is that off the list of things I should gripe about.

[Irritant]

Since around 1.5 I guess, I'd say the performance increase is very signifigant. I can get playable FPS on pretty much any map, with everything turned on. I generall just stick with the default settings tho.

No, its hard to find moddelers.. its still 'planned' though

Everything on & at max except for HDR, Bloom & realtime shadows:
2.2.3: 111.6956327 fps
2.3: 132.2766175 fps,

... So that's about 18% better, which is well appreciated. This has allowed me to enable realtime shadows while still experiencing better frame rates than previously.
The big performance difference is the reduced slowdowns, I read somewhere that multithreading was enabled for this release, is this correct?

Only for osx and only OpenGL calls are handled in a seperate thread by the driver if this option is enabled. On any other OS it's up to the driver whether it uses multithreading or not.
