Any word yet on when this game is going to get optimized for CrossFire (if at all...) ?
As most crossfire users probably know, the game when played in xfire mode is still mostly unplayable due to the extreme stuttering and screen tearing, problems that games which have been properly optimized for xfire don't have at all (e.g. Tomb Raider).
Have CDPR said anything about whether they plan on improving crossfire support, or are they just going to completely ignore this issue ?
Edit: Here is an insightful post taken from The Witcher reddit (not my post) that provides some more information about the problem that I am referring to here.

Despite 15.7, crossfire is still a stuttering mess in Withcer 3. Does Nvidia users/other AMD users have the same problem? (frametime analysis inside) (x-post /r/AdvancedMicroDevices)
Thought i would fire up crossfire again after 15.7 patch, but no dice. I specifically bought my second R9 290 card for Witcher 3, but i haven't benefited from it yet, which is annoying. Even with freesync, it is stuttering to an unplayable degree (for me).
Specs:
i5-4670k
12gb DDR1600
2x XFX R9 290
ASROCK z87 extreme4 (running PCI-E 3.0 8x/8x in CF and 3.0 16x in single)
All test are run with 15.7 driver and Freesync enabled (which works with CF now) Let's start with a game that has been criticized for it's optimization; Far Cry 4

Crossfire http://i.imgur.com/tfxJ7vn.png
Here we see quite a bit more stuttering (unstable framtimes), but the experience in-game is not THAT noticeable. I would definitely prefer the higher frame rate, over the reduction in stuttering in this case.
Now let's try with a game that actually has decent optimization for AMD; Metro: Last Light. I have to mention here, that i forgot to turn tessellation to "high" on the single card, so the performance difference doesn't look as dramatic as it is with the same settings.

Crossfire http://i.imgur.com/nyQyoUl.png
A minor increase in stuttering that is absolutely unnoticeable in-game. I was very surprised there was any difference at all, since it felt completely smooth.
Now let's look at Witcher 3

Look at it... LOOK AT IT!! It looks like a fucking seismometer when your mom walks by. It is absolutely unplayable for me.
How does yours look? Here is how you test it:
Download Fraps
Download Fraps Bench Viewer
Open Fraps and navigate to "FPS" and set a benchmarking hotkey, and check ONLY the "Frametime" mark.
Open game
When fully loaded press your benchmark key and fuck around a bit
Press the benchmark key again.
Open Fraps Bech viewer
Drag in the relevant log.
Right-click and save chart.
