Directx11 does what?

post #1 of 39
Thread Starter 
So I have been doing some searching and seen some videos on youtube and such comparing like directx9 to 10 and to 11...and I can't tell a difference. Maybe I am blind, or dumb, or a combination of all of the above, but I don't see it.

I play wow occasionally, and when I switch between directx 10 and directx 11 (on my other pc, since obviously this card doesn't support it), but I couldn't tell a difference, except a drop in frame rate. So basically what makes it so great?

I plan on upgrading this gtx295 to a 580 probably, but what exactly am I going to gain? This card seems really fast to me? I don't play a wide variety of games, just BC2, WoW, TF2, etc and this card has no trouble playing them on max settings...

I read that this card has lots of power and provides a high frame rate, without high AA. I am happy with that...I like my high FPS, if I go to a 580, am I going to lose FPS in games I play now? Granted it will probably look better when playing BF3, but how much better? Is it just going to have more "eye candy" but lower FPS? Or more "eye candy" and more FPS? Sorry if these are noobish questions and I tried searching...just couldn't really figure out what all these things put together equate to.

If you know a thread to point me to then please do.

Thanks in advance.

Well, if you basing this on WoW, then you need help. Look at games like crysis 2 because now they patched it, it looks awsome. some of the benifits of DX11 is tesslation which you can see makes a differance (well that i can see) becasue it adds a very nice level of detail to everything, just look at a brick wall in crysis 2, there is more depth and detail.

Take a look at this video:


Basically DirectX are some libraries, with already written function that programmers can use to increase the quality or the look of the game.
I guess a lot of change could be seen from Direct X 9 to 10, while 11 brought Tesselation as the biggest improvement.

You will not see a big (if any) difference in thous titles. In time newer titles will fully utilize the tessalation and shading options DX11 gives. Then you will see a big jump in grafics quality.

And tesselation does what? It reduces the amount of little triangles that makes up the graphics, making them more smooth and life like?

And if I am satisified with the way games look to me now, withOUT directx11, I am not really going to gain anything except pure "eye candy"? I mean if the gtx580 will provide roughly the same FPS as my gtx295, but with more "eye candy" then that is badass, and I am all for it, but if I have to trade framerate, for "eye candy", I will keep my frame rate.

i played a FPS where it was much easier to see through smoke effects with dx11 compared to dx10... maybe it was just me. but the smoke in earlier dx versions was less transparent, and less realistic.

If you want to see DX11 in effect download the Heaven Benchmark on your other rig and play with the tess setting and stuff.

tessellation just adds (tessellates) polygons to stuff so devs can get away with crappier models....

nothing special really.

what DX11 does help with is dynamic lighting. In BC2 for example, the shadows and other light effects are much more realistic in DX11 mode.
