Render times with TG2 final

[buzzzzz1]

Just ran the Latest benchmark scene from Oshyan with the final release and..........

With the Beta-->  0h 21m 6s   Intel Core 2 Duo - E8400 (2 cores)  3GHz  1 CPU  8 mb ram    Windows XP 64 SP 2

With the Final Release--> 0h 21m 51s     Intel Core 2 Duo - E8400 (2 cores)   3GHz  1 CPU  8 mb ram    Windows XP 64 SP 2

oh well, guess we can't have everything?

Really?  Well, this needs to be researched.

Hmm, I thought someone was quoting a 30% increase, thought it was too good to be true

that quote was not from Matt but from here 8th post down

Matt wrote in the Changes from 1.10.23.1 (Beta) to 2.0.1.1 (v2.0 release)

A small improvement to the performance of multi-threaded rendering.  I don't see 30% there anywhere though. 

I would be interested to see other results in the event that it may just be my machine and not TG. Anybody?

a lot of times a render increase in one place might mean a decrease in another.  could be some scenes where theres massive improvement, others with only slight, others who might even loose a little.  the goal is to not make it massive loss and preferably gains.

Also don't forget that new benchmark of Oshyan covers many aspects of the renderer, regarding reflections, soft shadows etc. etc.
In many cases all these aspects aren't involved at the same time and thus you can measure in increase in performance.
It's just how you look at it.

like i mentioned, the sample scene was fairly simple, no trees or water
- rendered on a 6600 quadcore (2.4 ghz) and 3 gb ram (since 32bit /XP os),
1:50min on the beta, approx. 1:20min on 2.0 release...

-guess i was a little to euphoric -

P4 Laptop 1Gb Ram
Terragen 2 Beta 1.10.23.1             1h 19m 12s
Terragen 2 v2.0 (build 2.0.01.1)     1h 15m 58s
apx 4% faster

so for me on my old p4 laptop I'm just under 4 min faster, not a lot but better than nowt

Q9450 Desktop 8Gb Ram
Terragen 2 Beta 1.10.23.1             0h 16m 5s
Terragen 2 v2.0 (build 2.0.01.1)     0h 13m 56s
apx 15% faster

The best way to find out is to do testing like Buzzzzz did.  I can't right now, but I will by this weekend.

Yeah, the errors we were having last time were from things that are being rendered this time.
My new render took EXACTLY the same time
Don't know how important this is because this is just a benchmark, not a standard rule for all renders, but I forced 8 cores on TG2 (I only have 2) and increased the subdiv to 800(/8 is 100MB per core) and the render time was still EXACTLY the same

In case i missed something: does this affect the render time?

[Tangled-Universe]

In a negative way, if you'd ask me?

8 mb ram .... 8 mb ram

i really hope you meant gb, otherwise i dont see how you run windows

The increase in render time depends on the .TGD. A simple preview with  default atmo, no clouds, done yesterday took me 12 minutes; today with the final version it rendered in 9 minutes.
Another TGD with pretty heavy atmo settings took a little over 2 hours with both versions. And from the progress a third render is making now I think it'll render in the same time as with the Beta.

I am continuing my Genesis animation with the new build, and it seems that planetary shots actually take longer.

In the old build a frame would render in about 0:50 hours, while the new build needs 1:50 hours. So that is a full hour longer, which is more than 50% decrease in speed...!
