The 15.3 Beta drivers are out. But you don't have the 285 anymore, do you?

Did you try the newest beta driver? 15.3 Beta is supposed to enable the feature. Try it out.

The Catalyst 15.3 Beta Driver release introduces Mixed Rotation Eyefinity Support.

Mixed Rotation Eyefinity refers to a configuration with the following layout:

Portrait - Landscape - Portrait (PLP)

An example of PLP Mixed Rotation Eyefinity is shown in the picture below:

Guys thanks for letting me know. I see they are clearly saying mixed rotation is now working on R9 285. So PLP is now supported (in theory, but very likely truth this time).

I returned the R9 285, was annoyed due to its lack of PLP support. And my previous card gave better FPS. Sucks, now I can't test it.

I am not fond of the R9 285. It's decent, but bit sluggish for maxed PLP. R9 390 expected release in June, will likely buy that. http://www.techpowerup.com/210453/amd-r ... -2015.html

I am happy ATM spreading games manually. But to have proper Eyefinity PLP support... that would be heaven. Other PLP enthusiasts must consider buying; makes PLP dead-easy.

I went out and got two R9 285 cards, and this works perfect!

I am going for a third one today given I am running 20x30x20

Excellent! Good to hear Crossfire works perfect in PLP. What games you tried so far? Do they run easy as LLL? And bezel correction works?

so far the experience has been great getting PLP Eyefinity.
With the R9 285 it is super simple to do, bezel correction works perfectly.
Running 2 R9 285 in crossfire and PLP works flawlessly as well.

Part of my testing involved checking the R9 290 card. It does not support PLP.

What I found out from a source at AMD is that the R9 285 chip is actually newer than the R9 290, that is why the 285 is able to do mixed orientation (PLP)
What I also found unfortunately is that the R9 285 is only capable of 2 cards in crossfire. no triple or 4 way.

So you basically have the following choice:

R9 290 for tripple or 4 way crossfire, but no PLP support
or
R9 285 for PLP and 2 card crossfire only.

Performance wise, I am getting 50 - 75 FPS in BF Hardline on med to high settings on 5200x1600 resolution with the 285 crossfire eyefinity.
This is seen on the video I did (see video on the front page story)

So far every game I have tested is fine
BF Hardline
CS:GO
Left4Dead2
BF4
H1Z1 (note there is no crossfire support in the game yet, but PLP eyefinity works fine)
