Is DX11 really that demanding?

post #1 of 33
Thread Starter 
Well with the Dragon Age 2 demo, on dx9 maxed, it runs around 90-120 fps, however when i change to dx11, it doesn't even look that much differnt and i can't get past 10 fps lol...so is this a game problem? Haven't tried any other dx11 games.

huh thats odd. from my knowledge dx11 is supposed to deliver higher fps, not lower... i could be wrong though.

espessialy with your vid card.

It's just dragon age 2 demo not dx11. A lot of nvidia cards are having a hard time with the dx11 version. ATI cards seem to be fine so I'm assuming it's a driver issue or just the game.

The PC demo has known performance and stability issues with DirectX 11. These have been fixed in the final game.

We recommend that all users disable DirectX 11 while playing the demo, including those with high-end machines.

I noticed the same problem. When I tried the demo my fps was horrid until I went dx9 and lower aa. Hopefully just an issue with the demo

Yeah I have an XFX 6870 and I run everything 40-60 fps but I didn't try it out with Directx9.
Though the game looks great and I hope the game and drivers will be better optimised soon biggrin.gif.
EDIT: Oh and that's on a 1600x900 screen on highest settings possible with vsync enabled.

Haha I had a major wth-moment when I tried the demo in dx11 mode too.

Luckily it's just the demo not fully supporting dx11 yet (at least on nvidia cards). The final version should be much better. biggrin.gif

O.o

In Metro 2033, DX11 usually cuts fps in half
