It's difficult to say... IL2 had a pretty good balance between Graphic Load on the GPU and of course FMs AI Damage etc on the CPU. IL2 scaled very well over the years and that tells me the code was pretty tight from a developer point of view.

It will be interesting to see if DX11 will have an affect on SOW. If WOP is any indication we aren't going to be that bad off even with current hardware. As Oleg mentioned they will unlock features over time as they continue to develop the sim. I certainly hope SOW is a success for them.

Just looking at that City Demo says that if they can take advantage of some of those newer card capabilities the future is pretty bright.

Actually IL2 is pretty CPU intensive. High end cards are overkill for it. You would be much better of with a powerful CPU when playing IL2 than GPU.

Here are some comparisons:

GPU & RAM tests

nVidia vs. ATI

I never found that to be entirely true at 1920X1200... I agree it weighed in more on the CPU but it scaled quite well in terms of FPS when throwing a high end card on it. Especially with the mods and eye candy stuff.

As I suspected his test is at 1440X900 with his card is really only going to show CPU scaling... You can say the same about my 1920X1200 being more video card scaling...

Think about this one: Heaven DX11 Tessellations benchmark is heavly sponcered by nVidia, and... nVidia whipes the floor with ATI/AMD benching that...
But in the only game (Stalker Call of Pripyat) that really makes a lot of use of Tesselation its totaly the other way around and the ATI/AMD cards basicly crush the nVidia cards wen benching that, Weird huh?

Benchmarks are only that... They measure something... Games on the other hand utilize a number of techniques and some cards perform better than others because of certain game features.


Just picked up my GTX580 yesterday. So far it works as advertised. About 20% faster than my GTX480 I returned.

Jee's I missed the boat, was thinking of ditching my pair 5870's for a pair of these. I've been dying to get my hands dirty with CUDA. My fav store has sold out

On the thread about the Moscow exhibition there's an interesting quote from mr. Maddox.

Long story short, he says tesselation in its current form is not very useful for the SoW engine. The reason is that since tesselation generates "protrusions" on surfaces on its own it results in a more or less unpredictable end result, one that will end up messing up their finely crafted aircraft models. I guess techniques like it are good for modelling complex but non specific things, like waves on the water or a cape flowing in the wind, wrinkles on clothes, etc, but not for things that need to be accurately shaped and sized in a predictable manner.
He says they might incorporate it in the future though.

Quite useful in deciding what kind of GPU to go for.

I think i've read that nVidia cards have more tesselation-specific shader processors than the Ati ones, but Ati cards usually have more shader processors overall (tesselation and generic).
This results in nVidia being faster under heavy tesselation load and Ati being faster under normal DX11 graphics that don't use much tesselation. Since SoW will not use it that much, i guess the best bang for the buck (esp since the new engine is DX based and not OpenGL) will be to wait for the new GPU releases and resulting price drops in previous series and pick up a 58xx series Ati card.

What would be interesting to know however is if tesselation applies globally or not. For example, is it possible to apply it only on terrain features and leave the carefully modelled aircraft alone?

That sort of thing has been going on since the late 90's.

The real test will be benchmarking Parallel Processing using OpenCL, only then will you see the true number crunching power of your CPU and GPU.
