DX9 Support for Battle over Moscow

For example, if you want to make use of DX9 feature levels in CoD simply edit your conf.ini file and chage it from DX10 to DX9.. Also, something not many people realise is CoD does currently support DX11! Problem is it is beta and not recomended! At the time of CoD relase DX11 feature levels still had some 'issues' (read buggie) so 1C limited the feature levels to DX10. But if you want to try the DX11 feature levels you can edit your conf.ini file and try them out. That is the beauty/benifit of programing the game using the DX11 API, the ability to switch to other feature levels

If they program it fully in dx11 it wont work in DX9. Shadow compling along with many other base features are different. Atm really game is a dx9/10 platform.

If they did that it would defeat the purpose of upgrading to the DX11 API..

Because one of the new features of the DX11 API is the ability to select different feature levels (DX9, 10, 11) on the fly.

The good news is they did NOT do that and you can switch to use different feature levels.

May sound silly to limit a DX10 capable video card to DX9 feature levels, but when it comes to 'visuals' it is so 'user' specific that some may like the look better, or, in some strange hardware configs find the game runs smoother at those lover levels.. Which I find hard to belive myself, but I have seen some folks make stranger claims than that!

lol ok... I am not going to start a fuss over this, you are wrong on a number of your points, DX11 has no API for dx9 features and such more then any other engine. Its determined by the way they compile the code, so you can use the dx9 method or the dx10/11 method and it will both run on dx11. This is different then what you said, its not the same thing.
Also all GPUs today sold on the market have dx9, In fact I cant find a dx9 only gpu in shops anymore, the lowest end cards you find now in the west for nvidia are bottom barrel 8k-9k range, now they are shipping out bottom end 400s so really nearly all new gpus from now on purchased will be dx11.

In any case I blew the horn on this whole compatibility issue in early 2010, go back a few hundred posts and have a look, nearly every prediction was correct

Really?

Well don't take my word for it..

Spend 5min an do a little research and you will see that I am right!

There are plenty of Microsoft Links on the subject..

But I know how the uninformed love to bash anything Bill Gates so instead allow me to post something from AMD on the subject, i.e.

Your Game Needs Direct3D 11, So Get started Now
More reasons to switch to Direct3D 11
Supports multiple "device feature levels"
-11.0
-10.1, 10.0
-9.3, 9.2, 9.1
-One API for all of your supported hardware

Nuff said?

If not set your conf.ini to DX11, or 10.1, or 10.0, or 9.3, or 9.2, or 9.1 and see for yourself!

Well the fact that you are making silly comments about "bashing bill gate" which I guess is in your world a humorous jab at calling me a Apple fan or whatnot makes you look like a moron out of the gate. I actually hate apple PCs, and I am not uninformed, so now I will have to mildly embarass you.

You quoted me as saying (which I did): "you are wrong on a number of your points, DX11 has no API for dx9 features and such more then any other engine"
You replied with this: "If they did that it would defeat the purpose of upgrading to the DX11 API..

Because one of the new features of the DX11 API is the ability to select different feature levels (DX9, 10, 11) on the fly."

First off I hate having to educate people so I will make this brief: In the above statement you said that one the DX11 api features was to select different DX levels. ZOMG, you do realize that just means that the API is backwards compatable? For example I could use a DX9 lighting system while also using dx11 tesselation. So its nothing new, its existed for nearly every DX upgrade (they normally build on each other) and the whole point of switching to dx11 is to use the new dx10/11 lighting features among other things. These are completely new for dx11/10 and are "new dx11 features" and they are NOT back compatible. However like said a older dx9 system can be used (of course, not news to anyone but you it seems) instead of the new code etc. Your statement basically was like: "upgrade to a new car, hover car, it can even use wheels if you want!" The reply is then wtf is the point of upgrading? (and the only reply would be say, a more powerful engine but the main selling point no longer is useful).

Actually that is not correct..

Your mixed up your quotes there.. That is to say that reply of mine you listed above was to a previous quote of yours, not the one you listed..

So to get this train back on track allow me to re-post it in the correct order..

And my reply to that was to post the link and excerpt from said link, i.e.

As you can see, my link proves your statement is in error, that being the DX11 API 'does' have DX9

PS it is done at run time, not compile time

Nuff said?

If the AMD reference is not enough for your, please read the following Microsoft link, i.e.

Microsoft DirectX graphics provides a set of APIs that you can use to create games and other high-performance multimedia applications. DirectX graphics includes support for high-performance 2-D and 3-D graphics.

For 3-D graphics, use the Microsoft Direct3D 11 API. Even if you have Microsoft Direct3D 9-level or Microsoft Direct3D 10-level hardware, you can use the Direct3D 11API and target a feature level 9_x or feature level 10_x device.

Now here is the 2nd link that proves your statment was in error..

Do you have anything to support your claims?

You are misunderstanding the terminology, support does NOT mean nativity. The DX11 shadows have to be compiled before they run, now you are looking stupid. Just google Direct X compile shaders.

Again, just because the DX11 engine is backwards compatable does not mean the dx11 compiled shaders and code is compatable with dx9 api content available. It is in the API, but its from the older DX version, there is a new DX10/11 version for the processes which is the most up to date version/best version. Its not worth arguing if you dont understand the mechanisms.
