R9 290X Crossfire will not increase fps? - Page 3

post #21 of 46
Can you crosscheck the results from this review?

It is not crossfire so it's not a direct comparison but can be interesting.

I just tested Remember Me.
I had the game max out with SSAA.
MSI shown 100 on both cards.
I tested an area
1 card = 132fps
2 cards = 165fps.

Should I not see at least 200fps if I get 100 on each card, or does it not strictly work like that?
Thank you.

It doesn't work like that. Some games you'll see less then 50% improvement over one card.

Also at really high FPS, you can start running into a CPU bottleneck. Try turning settings down- if FPS doesn't improve, that means you've hit a CPU bottleneck.

And that's why you should have gone for a 1440p monitor instead. biggrin.gif

These cards are literally begging you for more resolution!

This.

I get insane frames on my 290x Xfire setup.

I was under the impression that I could have downsampled to 1440p but it seems AMD shut off any method of downsampling.

Yes, this is what I've been reading. CRU won't work for me because any custom resolution makes the monitor go out of range (Others also report this) and AMD GUI does not work on 13 series drivers.

Here is some evidence of what's going on:

Battlefield 4 Settings:


CFX OFF (Window Mode)


CFX ON


GPU Usage (See highlighted area for CFX)


CPU Usage (CFX ON, 64 player server) Note: GPU usage was the same as image above)
