AMD Crossfire

[3uster3oo]

Hi, anybody else having trouble with AMD Crossfire since the full release. Worked okay all through the Early Access no problems at all with AMD drivers right up till 14.9.

But since the full release of the game getting crazy disco shadows and the only way to stop this is to disable Crossfire. Gone back down all the Catalysts I've used which were working before (clean install of windows each time) final release but no luck.

I have not had the disco shadows in IL-2. Have had them in WT before they fixed the crossfire there, though. The cards seemed to render dynamic shadows a little different, producing the disco.

But in IL-2 I sometimes have a few terrain tiles render as black on one card, and produces flickering. To fix it I alt + tab in and out, and the cards sync up properly. You could try it, but shadows are a different matter I guess.

 

What cards do you use, btw? (I'm on two 6950s. One 1gb and one 2gb with unlocked shaders).

[3uster3oo]

_{Thanks for the reply, just gave the alt-tab a go but no luck, I'm using 2 ASUS R9 290X DirectCU II OC 4GB with a LG 29 Ultra wide monitor 2560/1080. Never had any problems with any games really with them but there is always a first}

And that was wishful thinking.

I don't use X-fire myself, SLI here, but  what you mention is similar to what I've experienced.

I opted for Force Alternate Frame Rendering. Asking the two cards to render every other screen, or, if you like; upper half and lower half.

I do not know if this feature is available for X-fire, but I am quite positive something similar must be available.

Just a hint, in case your all out of ideas...

Yes, you could go into the CCC and make a profile for IL-2. It should then give you two settings at the bottom; frame pacing (which by standard is on and helps tearing), and AMD CrossfireX mode. Try switching that mode to use an existing profile, and search for the Rise of Flight profile. Seeing the game engine is developed from that engine, it might work. If it does not, try switching between the other modes; AFR and Optimize 1x1.

[kissklas]

Oh, and do write back and tell us how it went, if you try it:)

Cheers,

Klas

[3uster3oo]

Gave that a try with no luck, seemed to make it  a little worse.

[kissklas]

Haha. Oh no... It's probably a sign that I should stay away from giving advice.

 

You should at least make the developers aware of this. They will probably look into it, especially since the R9 290X is such a recent card as well.

I know it has happened in WT after a graphical update of some sort. Got fixed pretty fast...

 

Hope it gets solved soon. Will let you know if I find out anything else about it.

And sorry i could not be of more help. Had my hopes on the RoF profile!

Thanks for your help, will do that with devs. Only thing I haven't tried was untick the box full screen and what do you know, all good  .

but it is still a problem that needs to be sorted. Cheers

[kissklas]

Good stuff:)

 

However: windowed mode, in applications has a tendency of disabling crossfire.

You should do a quick check to see if both cards are active during play with full screen unticked, just to be sure.

 

If the game runs with no problem, anyways, I guess it's no real rush though.

But it should be sorted, of course, so that people can get the most out of their setup.

 

See you in the skies:)

S!

Yeah your right, disabled in window mode (bubble burst). you will see me in the skies I'll be the mobile disco not hard to miss

_{Update, been messing around with older drivers for a couple of day and found that the game runs okay in crossfire with only the AMD Catalyst 14.9 WHQL. Very strange ?}

Sorry I meant 14.8 WHQL.

[kissklas]

Well, I guess it's a good idea to stick with 14.8 until a new version is out.

 

Who knows, maybe BoS will have it's own crossfire profile:)

[RaptorBR]

I have two ATI 6790 in crossfire, cpu X6 1090T, 16 gb RAM.

 

I need some help. The crossfire with IL-2 BoS don´t work for me. I have DCS World and FSX, and for this games work fine. For IL-2 BoS the screen freezing and the game stop and don´t work more.

 

With crossfire off the game run but with lower fps. I try config in many ways the CCC but nothing make the crossfire work in BoS. Can someone help me?

[kissklas]

Hey sidneyparizotto

 

You should commit a bug to the developers through the forums.

It may take some time, but I'll try and help you to the best of my knowledge. I am also running crossfire on the 6 series (6950 x 2). It works out of the box here.

 

What exactly is happening when you start the game? Freeze on black screen and crash?

[RaptorBR]

No,

 

I start the game normally, start a mission normally to. The fps is very good using balance mode. 

 

But after a time in fly, for example after kill some enemy in 5 or 10 minutes, the screen freeze (and the game stop). The uniq way to back to Windows is with ctrl+alt+del.

 

 

In the task manager the game is "no working".

 

With cross fire off the game never stop but de fps is very poor.

 

Thanks for you help!

 

Sidney

 

PS: Sorry for my mistakes writing in english.

Thanks for YOUR help! (sorry)

Try downloading and running open hardware monitor, and running it while playing. Here is a link for the download.

 

Look fpr the max temp after it crashes. Seeing the game crashes after some playtime and unreguarly it could maybe be gpu temps running high.

 

Read up on the program if you like. It doesnt need installing and you can run it directly.

 

http://openhardwaremonitor.org/files/openhardwaremonitor-v0.7.1-beta.zip

[RaptorBR]

About the temps, it´s very low for all hardware. When running FSX they are much more high and the game don´t stop.

 

GPU 1 before play = 42ºC ......after play (and again the game stop) = 52º C

 

GPU 2 before play = 0º C.....after = 44º C

[kissklas]

Ok, so then we know it`s not the temperatures atleast. Could you maybe try adding the IL-2 BoS exe-file to a custom AMD crossfire profile in CCC, and use the the Rise of Flight profile (if there is one)? BoS uses a modified version of the same engine so it could maybe do the trick.

[RaptorBR]

I yet try this, actually i use now this profile  in CCC and don´t solve the bug. Today i try a lot of  overclocking configurations but in the end overclocking is the worst idea. I reinstall the Catalyst and drivers, but nothing. I don´t want reinstall the game but  in the last case  i think that i will do. Strange bug in a very good computer on the same time you can fly FSX and DCS, the first one much more old engine and very heavy software.

 

Thanks a lot for your help, very nice and friendly.

[kissklas]

As a fellow crossfire user, I do feel your pain. I will keep my eyes open for solutions:-)

 

If you are reinstalling, remember to back up your input folder so you dont lose the controls.

 

If you do find a solution, post it here so maybe it can help others:-)

 

Good luck!

[RaptorBR]

Unbelievable i solve the issue!

 

I never believe in easy solutions for complex questions. But in this case i found the solution  after try and try different configurations. The adjust that solve the issue is really unbelievable.

 

Maybe it´s a bug in the game. Or i´m all the time wrong in the way that i was starting the game.

 

I just unselected "full screen". But surprise, the screen is still in full screen when i play, and the game run fine and better,  and now in a full option.

 

I hope that i will now play without problems, because is just for fun and not for problems tha we play and pay for this.

 

Chees.

 

Sidney

Sorry again, the english,....Cheers

[kissklas]

Of course! Crossfire does not run in windowed mode in games, so that makes perfect sense:-) Brilliant! I'll see you on my 6'! Happy flying:-)

My Crossfire experience lasted exactly one day, and i am really disappointed.

But first things first.

 

My Rig: 

Windows 8.1

i5 4670K

20gb RAM

Ati Radeon HD7950

1920x1080 Monitor/Resolution in my Games

 

I analysed all my games with Fraps, and found only 3 which had FPS under 40, when every graphics option available maxed out: Arma 3, Rise of Flight, and Metro Redux

 

I bought another Ati Radeon, HD7970 this time (confirmed by AMD to run "perfect" with my card in Xfire) to run it in crossfire mode with my 7950, and tested those 3 games in crossfire.

In Arma 3 i got exactly the same FPS like with my 7950 only, around 20 when visual range maxed out.

In Metro it got slightly better from 15-17 to 23-25. Still not acceptable

In Rise of Flight it got a lot worse. From 32-40 with my 7950 to around 20 with Crossfire. (Crossfire mode of course enabled in the options) [That's ridiculous]

Didn't test BoS, because i got 70+ FPS in ultra with my card anyway, so didn't see any reason.

 

After that i tested those 3 games with my new 7970 alone, and the FPS got around 2-3 better then with my 7950. 

 

I am seriously disappointed with the Crossfire mode, i am pretty sure a single 4GB card would bring better results, then those 2x3Gb cards together in Metro, don't wanna even talk about the other 2 games. 

Will send the new card back, don't see any reason for keeping it, just wasted money. And wait till i really need a new card for a flight/space sim, but looking at how good my 7950 even runs the un-optimized Star Citizen, i think this might take quite a while

 

Hope i could help, if anyone here is thinking about trying Crossfire, and has a Card close to mine...

I just downloaded the latest patch to test how well crossfire is going to work, well it sucks still! & I had better crossfire performance during the Alpha & Beta versions of the game. ??????

 

I have two 290x GPUs clocked to 1060MHz/ 1360MHz a 3930k CPU clocked to 4.7GHz & 16GB of system memory driving a 1440p panel at 100Hz. I keep supporting this Il2 rebirth & can't enjoy the game/ simulator since I can't even get a steady 60 fps on High settings 2x AA, giant sad face.

 

(The problem must be since AMD stopped supporting the ancient DX9.0 API a while back?)

 

I forgot to mention the GPU usage is around 0- 30- 40% Huh? Confused?

Hey guys I just purchased the game yesterday after much experimenting and noticing that High and Ultra looked about the same and the GPU utilization was horible I though I'd try something different.

 

I chose to let AMD control the graphic settings and it worked like a charm, not only did I get better AA but also it finally used 100% of the GPU resources all the time at full clock speeds unlike before.

 

In the game I selected 1440p, Fullscreen, Multi GPU Support, Ultra, AA at 4 (not that it uses it).

 

In the new Radeon Crimson Software I selected the following settings.

 

 

In the Radeon Settings I tried Supersampling  for the Anti Aliasing method and the performance was bad, as soon as I selected multisampling it performed as AMD and IL-2 devs intended IMHO.

 

If you use the game graphic settings the GPU's don't run at constant power, with the Radeon Crimson software your GPU's will be at full speed and full power if the temperature threshold allows it..

Turns out disabling HDR fixes the textures and antialiasing issues I was having with IL-2, now I am using the games AA on 15.11 Calatlyst after reverting back from Crimson, I'll be trying the new beta now for 15.11.1 Crimson. I'll be glad to have freesync back for DX9

 

I was wondering why my textures didn't look as good as I saw online but as soon as I disabled HDR everything loads nice and sharp.

AMD drivers set multisampling as a default setting, so that can't contribute to the change in performance. I tested the Crimson driver with my set up, but the toastyx pixel patch would not work so I reverted to 15.11s. As an AMD GPU user I have been struggling to get good performance from my rig, grant it I had better performance with the alpha & beta. Radeon Pro is a good tool I used during the alpha & beta phases, lot of graphic & multi GPU tweaks, sad when the Dev left its creation.

Turns out it was a bug with crimson, CFR wasn't working and if left on would limit it to 55fps even if it was set to 144fps wich would limit the GPU usage, using the Catalyst AA seemed to override CFR or I could have turned it off. Crimson still has issues like IL-2 BOS runs like crap and Freesync and Vsync doesn't work right for IL-2, even though it's supposed to support DX9. 

 

I reverted to 15.11.1 catalyst and the issues are gone, I now just use the game settings. I also found using HDR didn't load the textures and AA correctly, I was wondering why YouTube videos  looked so good turning that off fixed it.

 

So the info I posted was wrong as I started using IL-2 on Crimson.

Edited December 2, 2015 by astrix_au

[AstrixAU]

I have since reported the bugs to AMD through their reporting system. Hopefully IL-2 on Crimson when stable will be able to run better and with freesync.

I fixed my graphical issues by simply turning off HDR and SSAO. I finally fixed the ghosting issue that was caused by SSAO.

I think HDR is more affected when SAAO is running, as now it's not affected the same way but I have SAAO off. I done testing for now. I'm leaving them moth off I think.
