Single 5970 can't run eyefinity with DX11?

Very good vid I just watched but left me with some questions. I would like to hear what people have to say if theyve been using eyefinity?

Thanks

and in that video he demos ef with l4d.. i wonder if the side screens just act as a peripheral vision maybe? I think that would make me motion sick.

He says in the video it's most likely due to the ultra high resolution he's using.

 

[shevanel]

yeah I know, it's impressive how high the res is and this card perfoms so well on DX9.

I'm thinking it's a DX11 card that cannot run eyefinity on 3x30" lcds in DX11.. $600 card.

 

[erocker]

What a shame for the ultra-rich! A travesty!

I wouldn't be too worried since the cards are on their initial drivers. It'll get fixed.

 

[shevanel]

this might be a dumb question but why si the cpu usage so low? Why then do people discuss bottlenecks, does cpu usage have anything to do with bottlenecks? More importantly, low cpu usage.

 

[erocker]

No bottleneck here. You would need a current generation of any brand of CPU to be running sub 3ghz for any bottleneck to begin happening. Even with a 5970 I'm quite sure.

 

[shevanel]

so if the cpu usage is higher that means the card is doing less work?

Well some games are just not CPU intensive
Racing games in general are pretty easy on the CPU as long as no physics effects are run on the CPU.

 

[shevanel]

is that a good thing or bad thing?

 

[Zubasa]

is that a good thing or bad thing?

Its a good thing, the game is utilizing dedicated hardware to do the job.
GPUs are co-processors afterall, and they are meant to be used.

 

[shevanel]

So GTA4 could be a good example of a game that is CPU intensive?

But if it's not using the dedicated hardware for the job how does a GPU more powerful benefit?

 

[Mussels]

a certain amount of CPU power is required to feed the video card.

Then there are games that just use tons of CPU power for non graphics tasks. (most RTS games are heavy on the CPU, for example)

So depending on the game, you can end up CPU limited a lot faster

 

[shevanel]

Well maybe when they fix eyefinity on xfire then they can use 2 x $600 gpus to power DX11 on those 3 x $350 monitors.

 

[Zubasa]

It seems that it doesn't require much CPU power to just feed the graphics card alone.
For example, Furmark runs just as fast on a Phenom II 810 @stock as an i7 @4Ghz.
But then, there is Vantage that do get affected by CPU much more.

 

[Binge]

If you look at the GPU score only in vantage only the CPU has very little to contribute.
