The AMD Driver Thread

It's the HIS 7970 IceQ X² GHz edition.
I just tried your settings Matt, and I'm still seeing the same thing. It's very frustrating.

That's odd it said R9 290 on afterburner, well i guess that explains your stock clocks then.

Try with my settings but lowering the quality down to very high or even high. Using Vsync with Triple Buffering seems to be key in this game. Not sure what else to suggest as it plays fine for me I'm afraid.
 
I'm getting decent FPS and crossfire seems to be working pretty well, even with my 8320. Have the occasional dip down to around 45 FPS.

These are my settings, any improvements you can suggest Matt?

Looks good to me benny. You can try enabling fur as that is not GameWorks, it's the option after fur that is.

I expect if you change one of those ultra's to high you might get 60fps solid. Of course if you don't mind the drop then leave it as it is.

Good fps from a 280 Crossfire setup considering the notorious issues with this game.

EDIT

Try with Vsync enabled and Triple Buffering on.
 
Would turning anti-aliasing up force more load onto my GPUs? They never seem to go higher than about 60% usage.

EDIT: Also, which options are GameWorks stuff?

MSAA is bugged in the game last time i checked, but you can try it.

How did Vsync and Triple Buffering work? TB is in advanced settings.

If you enable a GW option it flashes up on screen i think. I think it's HBAO+, Fur+ and enhanced godrays.
 
@AMDMatt

What FOV do you use on Dying Light?

Have you tried Vsync off followed by waving your mouse around, just to see if you get big fps drops?

Thank you.

Erm, not sure what it is. It's quite high i think, 100 maybe?

I've not tried it with vsync off, but i will next time. I prefer having vsync on personally.

HT is enabled, but as with most games they perform marginally faster with it off. (Mantle games aside as they use the threads)
 
100? I get a 10fps drop going from 80 to 85.

Ugh, maybe I've got that number wrong I'll have to check next time i load the game up.

Matt

Do you have any AMD contacts for asking about 'Freesync' support with manufacturers.

Most monitors obviously can't be updated with firmware, but Panasonic sell a range of LED TV's that are regularly firmware updated and have DisplayPort 1.2

Specifically the AX802 line (AX800 in the states)

If they could work with panasonic to get it implemented, it would be epic...

This is my personal opinion, but I wouldn't expect to see any monitor makers offering firmware upgrades.
 
Matt, I think you need a crossfire thread - one that details games where it works, those that don't, and those that need particular tweaks (and what those tweaks are).

I know you have a crossfire thread of sorts, but perhaps one just dedicated to games would be good.

Ok, I'll see what i can come up with.

Swwwwweeeeeeeeeeeeeeeeet!!!! Never has FC4 played so well! I originally beat the game just using single gpu with a couple settings turned down and averaging around 50ish fps @ 1440p... now it just sits at my refresh with vsync on (96hz) with no dips. I'm seriously impressed! I only get about 52% out of my gpu's (3) but that could just be the vsync lock. Only every once in a while will I get a little hitch and it's always after I've been driving a long way, but man if the game launched like this I would have pooped a brick. SO HAPPY! :D

Now time to fight some Yetti's!!!

Good to hear.

This game seems to really benefit from using Vsync and Triple Buffering, playing very smoothly here as well using the same settings.
 
I tried with vsync and triple buffering, and while it ran better, it still had the hitching every few seconds.

Though I feel that vsync and tb are kind of just masking the issue. Like I said, it seemed to run much smoother on AFR friendly, but that has a strobing/flickering affect

What in game settings are you using, got a screenshot?

Infact, just copy my settings as that works flawlessly for me. Bugged AA disabled and all GameWorks effects off.

Right, this works smooth as a babies bottom locked at 60 FPS with 2x290X 8GB running underclocked at 1000/1250, stock is 1010/1375Mhz for these cards.

Copy my settings and see how it works for you. Run your gpu's at stock for now as i see you've overclocked.

That was using 2x290X cards with two disabled, 60 fps locked stable and smooth.
 
That was on anything from high to ultra (without any gameworks settings), and custom with enabled vs and tb.

The problem was barely noticeable at high, but there.

Like I said, enabling vs and tb is likely just masking the issue - how does it run for you with those disabled?

I used to have a similar issue with BF4 - and managed to mask it with vsync. Didn't mean it wasnt still a problem then.

BF4 for what its worth, runs like butter these days. But then, it is a year and a half old now :)

People have to tweak settings to get smooth single gpu performance, so it's not surprise that the same is required when you throw another gpu into the mix.

It works perfectly with Vsync and Triple Buffering on so that's how i play it.

How do you mean it masked the issue?

If you had stutter with Vsync off and turning it on makes it go away, it's not masking it....

I'm quite happy to play with Vsync on for once...

Same here.
 
Matt, I said above the issue is still there on high settings...

Should I run all my games on low? I am likely ever to see a problem then...

So, are you saying it doesn't run smoothly with vs and tb disabled?

Run all your games on whatever setting works best for you.

This game runs smoother for me with Vsync and Triple buffering enabled whether i use one, two, three or four gpus.

By the way, the triple buffering fix seems to be fairly common.

Thinking back, Farcry 3 had the same problem. The way to smooth the game out was using Vsync and triple buffering.
 
No need to get snarky.

You know its about more than this game that I am unhappy currently with crossfire.

If this is a cross-vendor thing with this game, fine. I tend not to follow game performance too strongly on cards I am not using.

Not snarky, I'm unable to post in that thread as per the forum/vendor rep rules.
 
What really bothers me is there are many effects that i dont like, purely preference which i can turn off, but the one that i dont like and that actually hurts me i can not in an increasing amount of games with a few exceptions like Alien: Isolation which it can be turned off, Oh that's GE title ain't it,,, save you the plug.

Alien Isolation is a shining example of how you optimise a game to run perfectly on all hardware. Was a pleasure to play that game and did not encounter any issues on day 1.

Scary as hell! :D
