2.4 performance

[zenwalker]

I've ran some performance benches between this & the previous 2.3 release. Some will be very happy & others will be slightly disappointed.

These results are from an E6300 @ 3.15GHz paired with a 7950GT @ 700/1680MHz:

1024x768, normal quality:
* 2.3: 1910 frames 9.9498260 seconds 191.9631559 fps
* 2.4: 1910 frames 9.5607200 seconds 199.7757498 fps
1024x768, ultimate quality:
* 2.3: 1910 frames 25.5537291 seconds 74.7444725 fps
* 2.4: 1910 frames 19.8623669 seconds 96.1617519 fps
1440x900, normal quality:
* 2.3: 1910 frames 10.3004189 seconds 185.4293526 fps
* 2.4: 1910 frames 12.4173491 seconds 153.8170494 fps
1440x900, ultimate quality:
* 2.3: 1910 frames 30.4542651 seconds 62.7169952 fps
* 2.4: 1910 frames 34.6376250 seconds 55.1423489 fps

^ That's not good news for those of us with LCD screens that look poor under their native resolutions.

Feel free to post your benchmarks & comparisons

Strange thing happening there with the 1440x900 resolution. Can you try a third resolution (1152x864, 1280x800) and see what that comes out as?

[zenwalker]

1152x864, normal quality:
* 2.3: 1910 frames 10.0287750 seconds 190.4519749 fps
* 2.4: 1910 frames 9.6969891 seconds 196.9683567 fps

^ Not much difference from the 1024x768 results, maybe the wall's at 1440x900 or equivalent? Could someone run a comparison of higher resolutions?

[Ed]

Normal and Ultimate are different settings in the two versions, what are you trying to compare? 2.4 introduces reflections (slightly slower). Are you trying to compare with everything graphically the same or not?

[zenwalker]

Is normal a different setting also? Even if so, what's with the huge difference @ 1440?

[esteel]

I think even normal settings got adjusted a bit.. But one would have to compare the config files to be sure.
Well it could be a driver issue that 1440 runs that 'bad'.

[zenwalker]

I think I was simply too eager to put them through their paces.

With the settings manually set to sane levels there's little difference at 1024x768, though gains are actually noticeable at my native resolution of 1440x900. The presets must be quite different and whatever the difference may be, it certainly causes slowdowns at higher resolutions.
