Crossfire.

[ALXAndy]

Can some one please, without this thread turning to crap, tell me how Crossfire is as of today please? I also need clear information on..

What games does it work well in? does it work well in Witcher 3? because as of now I would love to run it at ultra @ 4k with Hairworks on.

How does one disable Crossfire so that it completely goes away and does not cause stutter ?

Any other information would be gratefully received.

 

[ALXAndy]

And the games it doesn't work with please?

Yeah that's what worries me. There's also the issue that due to my rig layout using a standard Fury on air would be bad, as the intakes are not sufficient enough to feed an air cooled card. So it would have to be another X and that's money. And I don't want to spend money ruining my gaming experience.

I've not found any games it doesn't work with O.o And the easiest (by far) way around poor xfire would just be to switch to windowed mode, as xfire only works in fullscreen - which is actually my biggest issue with crossfire, I like playing borderless :/

People's perceptions of what is excellent and what is quite poo though differ massively.

I recently ditched two Titan Blacks as they were beginning to creak at 4k. People say SLI is amazing and works really well? well I don't agree. I thought it did, but certain games were unplayable and I think I know why. Basically I could get 40-60 FPS out of Witcher 3 at medium settings. The issue is though it was like I was drunk.

It did not stutter but it just felt very strange and controlling it seemed a bit of a lottery. I am guessing it was Gsync that was making the game feel weird, and whilst it did remove stutter it added in a very odd sensation when the game was moving fast.

It was so bad that I literally could not play the game. Going from that to one card? it's absolute heaven I just wish I could crank the settings even higher.

Not that one Fury X is not enough for 4k gaming because if you are sensible it more than does what you would want it to but yeah, now that I've sorta fallen in love with Witcher 3 I would like to see it at full settings.

I found, with crossfire 290s, that some games that I'm sure previously worked with crossfire 7950s at 1080p didn't work at 4K. They were old games mind, so maybe that was the reason. It was Assassins Creed Brotherhood and X-COM.
Assassin's Creed doesn't work at 1440p with crossfire 290s either, but X-COM seems happier at 1440p with crossfire. Not that either of them need it.

As of right now I would only want it for Witcher 3. I know I won't need it for Fallout 4..

I may just stick to my original plan of getting a Nano and sticking that in there for a 4k boost.

I don't even know if I could mount another rad tbh I need to investigate that more thoroughly.

 

[ALXAndy]

I'm not worried about that with HBM. I never use AA at 4k either.

Well I found out yesterday that the flickering issue I had with my Titan Blacks was down to a bug in the driver and was caused by Gsync. It was so bad I could not play the Witcher 3, even though I was getting a supposed 45 FPS easy. It just felt like I had came home drunk out of my skull and was attempting to play video games (and yes, I've tried it..).

I think the way to go is Fury Nano. I'm worried that another rad won't fit in my rig and would prefer it small and not so intrusive.

We shall see but all I wanted to know really is if I can *successfully* disable Crossfire so it's like it isn't even there. If I can do that without consequence I will be happy.

 

[ALXAndy]

Yep can do that fine, you just go into the CCC, and click on Disable Xfire, screen will go black, come back, and you'll then only be running on 1x card, ive tried it a few times, no issues

Wicked thanks. I think it's Nano all the way then unless they are total cack.

Matt every time I used that game specific thing nothing happens. For example, Borderlands has no Vsync. So I put it on on the profile and nothing happened.

That's why I am worried. I even tried global Vsync and that didn't work either.

One Fury X takes care of 4k but it would be nice to have a second card so I can boost game features a little.

 

[ALXAndy]

Oh I see. So that would be why that doesn't work then..

It's not Crossfire I want to work in BL it's Vsync. The game doesn't have it so it's tearing city. Obviously when I was running Gsync that made it work.

What I want now is a hacked Freesync. I know my monitor technically supports it but obviously doesn't because it's Gsync but it has the correct Displayport input.....

 

[ALXAndy]

Well from what I read there wasn't really anything specific about Freesync you just need the correct HDMI/DP that supports it.

Not too hopeful atm and hey, whining about a game that's donkey's years old isn't really a reason for it. My wife and I are nearly through it now any way, and BL2 supports Vsync..

Issue is my wife had a stroke, so her bearings and balance are a bit off. Therefore I have a dual monitor on her rig that I look at, so that I can see where she is and offer her directions if she gets lost etc. Problem is it's tearing city on both our rigs (she runs 1080p with a Titan Black and I run Fury X @ 4k).

BL2 should not have these issues though, so hopefully once we crack "the vault" we can move on
