Its a strange response from Luthier, multi GPU's being supported does not mean that there will be a toggle switch in setup options for dual video cards, I guess he's saying that yes 2/3 cards will work but the game as not been coded to take advantage of them, but then again Il2 was the same but you could force SLI (nvidia) through the driver settings. Why we cannot get a straight answer on this though is anyone's guess. :confused:

What applications are supported with SLI technology?
SLI technology can be enabled for every gaming application, including both OpenGL and Direct3D gaming applications. SLI technology provides either 3D performance scaling using alternate frame rendering (AFR) or split-frame rendering (SFR) or increased visual quality using the SLI Antialiasing mode. In order to provide the optimal 'out-of-box' experience for its customers, NVIDIA has created an extensive set of optimized game profiles which enable SLI scaling automatically. The full list of these SLI-optimized games can be found here. For applications not found in this list, simply follow these quick instructions to set up a new game profile to enable SLI technology. Information about professional application support can be found here.

Why don't all games see performance increases?
Applications which tax the GPU will see tremendous performance improvements of up to 2x with SLI technology when using two graphics cards. Most of today's hottest games and as well as next-generation games fall into this category. However, some applications, typically older generation applications, are limited by factors other than the GPU's processing power.

The most common limitation is the CPU. If an application becomes CPU bound, no additional graphics power can improve performance. This situation is most common at low screen resolutions like 1024x768 with no additional functionality turned on. Turning on antialiasing and anisotropic filtering or switching to higher resolutions can often move the processing requirements back to the GPU.

For CPU-bound applications, NVIDIA offers a new SLI rendering mode called SLI Antialiasing. This rendering mode allows you to enable SLI8x, *SLI16x, or SLI32x (for quad SLI only) antialiasing and enhance the visual quality of any gaming application.

???

In IL2 there is a switch in the conf.ini file where you can select cores.
I leave at the default, but it is available.

Yes, I have a quad processor too.

Have confidence in the developer. The processor cores and multi-threading is not going away for awhile. You can expect the ability will be available to those who want to more specifically manage their hardware.

Especially, with dx11 on the near horizon there will be alot more to the COD configuration than the 10 year old IL2.

Yes it appears that way Swiss, if its not known that dual cards make any difference to how the game performs then I would imagine that Cliff Of Dover falls into the the typically older generation applications.

Thats true Nearmess, but there wasn't any switch for multi GPU's which is what is being discussed. However you could force SLI through the driver or 3rd party programs such as nHancer which did increase performance, it seems this may be the same for Cliffs of Dover, however we currently have no idea if it will increase perforamce. Worth noting though for anyone about to splash out on two high end GPU cards.

This is a simulation not a typical Call of Duty type game. It doesn't matter how "new" an application is if it has to calculate complex damage modelling instead of hit boxes/hit points, Flight modeling instead of up/down/left/right, Artificial Intelligence instead of scripted movements, and large sandbox maps instead of corridors.

Point being that, much like other newer sims like ArmA2, you can't expect the GPU to do all these calculations no matter how much you might wish it to much like you can't expect your shiny new 2000dpi mouse to make your game run any faster. It's the CPU's job, not Oleg's.

Feel free to pile on more AA + AF or screen resolution though and be happy for that.

I've just posted this at SimHQ too, but here goes: SLI-Crossfire performance is entirely dependent on driver implementation. It is not coded for within the software itself. I expect Tree to argue with me, but the truth is, as usual, he's wrong, and does not understand how it works.

You don't understand the difference between choosing to allow Physx support and running SLI.

Yes, I missed that about multi-gpu. I really haven't thought much about SLI or crossfire, since my last system build. I realized at that time there really wasn't much performance difference between SLI and a good single card. I concluded it was just more heat and problems than I wanted to deal with for my evening ventures into IL2 land. (10 yr old sim)

I understand, the SLI and crossfire have developed a great deal in the past 2 years. I think planning for the future makes sense, but I will still want to wait until I have good familiarity with the BOB COD. I believe patience pays, especially when taking on improved technologies.

However, the more I think on this I think it is less an issue for BOB developers as it is for the processor/VC manufacturers.
