Please guys I just bought my second 5870 when I enable CF in options menu and ingame (fraps), although I can see about 80+ 130+ fps the game runs not smooth at all!!! Tried enable/disable vsync but doesn't do anything at all. I've seen this problems in several forums, I don't know what can i do... if it doesn't have solution 150 pounds rubbish... I mean. I can sell it but is not the way, I want to play smooth.

Any idea pelase?

Drivers or whatever please...

Should be smooth as silk with a super cpu like that. As suggested, check Afterburner.
 
Unfortunatley it sounds like you are experiencing the bane of dual gpu setups which is microstutter.

This is why I went back to a single card setup a few years ago and never looked back. I'm afraid its something that can't be properly fixed at this time :(

I have a friend with 2 x 5870 with exaclty the same problem.

OP, unfortunately there may not be a fix as he cannot find one and has tried absolutely everything.

Until I no longer hear of these problems happening, I shall be sticking to single cards.
 
I use to have 2 5870s and for the first month or two they were fine in most games, then came a lot of bad crossfire drivers, thats when it was quicker just using 1 card!
 
All I can really say is.

1. Make sure you have installed the profiles. They are seperate to the actual drivers.

2. Turn on the Crossfire X indicator. This will then display a logo top right or left (you can change it IIRC). It doesn't really help much, as it can come up even if it's not right, but hey, worth trying any way.

3. Try a few games. See if it's a global problem or something less sinister (like a specific game or app).

4. Try changing the order of the cards. Flip them in the PCIE slots.

5. How many bridges did you connnect? I always used two just to make sure.

Whilst known as Micro stutter it's really no such thing. It's flickering caused by a delay between the GPUs when post processing is used.

This is why Benchmarks say one thing (lots of lovely FPS) but in the real world you get the opposite. If it was stutter it would hit 0-5 FPS.

But hey, last time I brought that up I was talking out my ass.
 
Take one card out, reinstall drivers with one card, power off, put the second card in with the crossfire cable and power on.

Try that, i had a similar problem with BF3 (with CAPS installed ), has stuttering, did the above and it seems to have sorted it.

I have read sometimes with crossfire the drivers don't install correctly, whether thats true or not i don't know.

I have 2 x 5870 with no problems.

EDIT oh and I'm running the latest drivers WITHOUT the caps, and mine is running fine
 
What I would suggest is to completely uninstall the previous driver (including reset) and then install the new ones... Always done the trick for me.

Hense why its called Microstutter, which is the industry standard name for it ...:rolleyes:

Article that explains it in full detail here

Also, no matter what anyone else says there really is no current fix for it unfortunatley, it is a by-product of Alternate Frame Rendering.

The actual technology is flawed so no type of changing drivers or any other proceedures will completely fix it.
