Directx 11 Vs Dx10 Vs Dx9

[EeLeYe]

I've started looking into graphics cards and have been wondering whether to go a high end older card or a mid-range newer card.

One factor is the directx support. I had no idea what the difference was until I stumbled across this thread (yes, it's from 2009) that explains and shows the differences very well.

I tried using the ol' search button but didn't find anything explaining the differences.

Here are some pics of the same scene, but under the different versions.

You'll notice that the differences between DX9 and 10 are minimal with only better shading and light

DX11 is like a whole different league; more 3Dness so to speak - the biggest change is the detail in the road.

I know it's an old subject and I'm a couple of years behind but I figured it's good to know the differences. DX11 is definitely the way to go.

Windows XP - DX9 ONLY

Windows Vista - DX10 (can be updated to DX11)

Windows 7 - DX11

i would go Dx11 no point going backwards

and something like ati 6870 1gb is pretty cheap nowadays

http://msy.com.au/product.jsp?productId=6837 $229

i can only find 1 Nvidia in a similar price range

http://msy.com.au/product.jsp?productId=7305 $277 GTX560

get the 6850, its cheaper and you can flash it to the 6870

[Madaz]

^^ do that x2 :D

[EeLeYe]

Serious?? So the 6850 has all the same components as the 6870 and the only difference is the just firmware??

That is AWESOME.

[Madaz]

no they would differ ever so slightly

but not enough that a different firmware would kill it

[bozodos]

the 6870 is probably a higher binned 6850. So whilst it may work on most cards, there is potentially a portion that won't work after flashing it. I could be wrong though, cbf researching.

BTW that directx 11 shot seems to be showing off tesselation more than anything

Well apparently that's what dx11 is all about. It's basically dx10 but with completely revamped tesselation properties.

I think instead of having multiple levels/layers of models, they have only two. Dx10 and earlier would have the lowest detailed model up close covered by the next level, covered again by another level and so on; therefore all levels are loaded for up close models even though we only see the last level/layer. Dx11 on the other hand will only load the highest detailed model close up until a certain distance and then change to the low detailed model.

6850 is same as a 6870, with minor diffs, but you reflash bios and it works 100%, out of the 30-40ish ppl i know on the overclocking forums, all their cards work fine

DO IT!!!

i for one, just bought the gtx570 which just kicks pure assssss!!!

[Madaz]

the main difference would be pipeline's and stream processing units and a different transistor count

but yeah FLASH it

Haha. Fk driving on it too. Stiff suspension + road like that = fkd spine; and forget it if your busting for a piss.

Hey guys,

I just installed a genuine copy of Windows 7 64-bit Home Premium.

I am not sure if my operating system is now running Direct X 11. How can I tell or where do I search in Windows 7 to find if it is?

My PC specs are as follows (if its of any importance) -

• Intel Quad Core 3.2ghz
• 4.0gb 1333mhz ram (yes I know that's sh!t, i'm upgrading to 12gb 2000mhz soon!)
• Gigabyte 1gb graphics card (can't remember the exact model name, paid about $300 for it just over 12months ago)
• Asus mother-board (once again can't remember specs etc)

My PC runs games such a COD: Black Cocks & Battlefield: Bad Company 2 one maximum graphics and runs both of them smooooooooth as silk, both in singleplayer & multiplayer. WoW runs perfectly smooth, you get the idea.

Run 'dxdiag'?

[Madaz]

your OS is running DX11 but doesn't mean your gfx card is

yeah really need to find the model of your gfx card, use GPUz to find out what gfx card you have

I'm pretty sure my graphics card is an ATI Radeon HD 4850.

It seems to perform very well, and when i had XP and the Catalyst Control Centre installed, i overclocked it and it still ran fine and didnt overheat etc

[Madaz]

4850 are only DX10 5*** series went to DX11

[syfon]

ahh ok. i can upgrade to a newer series gigabyte graphics card fairly cheap though!

[Madaz]

yeah that's right the 6*** are cheap as chips atm

[syfon]

Just ran "dxdiag", and my system is runnign Direct X 11.

My gfx card is a Gigabyte HD 4870.
