I recently bought a pair of ATI Readon 5870m's for my Alienware M17x R2. After installing it, I noticed a huge issue playing Far Cry 3. I assumed it was an issue with Far Cry 3 and CrossFire. Major "flickering" or "shuttering", the whole screen not just shadows. Disabling CrossFire fixed the issue. After I finished the game I re-enabled it, went to play Planetside 2, same thing.

Downloaded and ran Catzilla (new benchmark software).

When Crossfire is DISABLED, I get better score then when it is ENABLED. The flickering occurs during the benchmark test as well. I managed to capture it on my phone.

Also there is a "fluid test", and it looks better with CrossFire DISABLED, then with it enabled. I have these video files uploaded to Google drive:

I am an IT guy, but my knowledge of CrossFire and SLI are limited.

Any Help would be appreciated.

i'm afraid it no one mighty be able do anything.
cfx or sli are just not worth it in games.
it has issues like micro stuttering, cou bottlenecking, driver problems etc.
a lot of people have given up on sli and cfx.
and does your motherboard have 2 16x slots? that might be an issue. what is your cpu?
but again cfx is just not worth it

This is the readout on the motherboard specs:
PCIe x16 bus supporting x16 PCIe MXM 3.0 graphics cards

CPU is older, i7 720QM

I was running 4870's in CFX just fine, no issues. Bought the 5870's just to stretch the laptop a couple more years.
