Multi gpu support.

Multi gpu support.

I didn't bother to check as it is something you expect to be there already, to my surprise the game was only using one gpu on my card.

 

[Mato87]

So give us more info, what card are you using, what drivers and so on, come one, don't be shy.

 

[tahirahmed]

Are you sure you have the latest Nvidia Game Ready drivers ? (assuming you have Nvidia GPU because AMD didn't released new drivers yet). If not then get the new drivers and after installation make sure you enable SLI in Nvidia control panel (it gets deactivated after new driver installation).

 

[saucefar]

I am using a 690 GTX with the latest drivers 3.52, sorry forgot to include that.

It is only using one of my cards for sure.

 

[tahirahmed]

I think it's 352.86 if I am not wrong and yes your SLI is activated and should work in the game, both of 980's got utilized to the max so I am not sure why it's happening like that on yours.

Maybe you uninstalling entire driver using DDU (Display Driver Uninstaller) and reinstalling will fix the issue ? not sure but for me it fixed SLI issues sometimes.

Woah - is that true? As in - happens everytime to everybody true?

If so then the benchmark I did this morning was way off and I didn't have SLI enabled.

EDIT: Apparently it is true.... yay!!!! That means I've been benching on 1 gpu. Doh.

 

[saucefar]

Let me give it a try, what driver should i get then ?

I am going to try a game i know that has support for more than one gpu, i am pretty sure it is the game at this point.

GeForce Game Ready 352.86 WHQL

GeForce Game Ready 352.86 WHQL

That is the driver i already used.

Yep it is most certaintly the game that does not allow me to use both my gpu's, i had a test in a few other games including Attilla and both gpu's was used just fine.

Yes that happens every time you update the driver

Glad to know your benchmark will be better now

This is weird, bear in mind that gtx 690 is a dual-gpu card, that means you have only one physical pcb and two graphic chips on it, using only one pcie slot and this may be the problem, I had a dozen of issues with my older gtx 295 which was a dual-gpu too, sometimes the sli just wouldn't work at all and sometimes when it worked I had these terrible stutters and so on.
I don't know how could I help you, maybe try and create a support ticket through nvidia site or try geforce forums, people might help you out more there or try to look into the release notes for the current game ready whql driver and see if the gtx 690 sli profile was added for this game for your specific graphics card.

Nope. SLI is working fine for me. Both GPU's firing on all cylinders.

Well what gpu/gpus do you have

 

[Zanderat]

Well what gpu/gpus do you have

Should have said that... dual GTX 760's w/ 4 gig vram each.

 

[saucefar]

Here is Attila as an example and it utilize both my gpu's on the card.

Reason for the lower temperatures, i only just opened the game for a minute.

And here we go The Witcher 3.

http://gyazo.com/aa8f0193192c8362a20e2abf423cf648

Latest driver 3.52 and yes i am running the game in full screen.

I am sure the game being a console port has nothing to do with it *cough*

Last game i had issues with was Company of Heroes 2 and we all know how that game went.

As I said dude, you should head onto the geforce forums https://forums.geforce.com/default/board/33/geforce-drivers/ and create a topic there, those people actually know their stuff and nvidia reps constantly read and answer every single topic created there.

Hi,

i using an R9 295X with latest 15.4.1 beta driver of catalyst. Its not possible to use Crossfire.. I can choose AFR mode on the crossfire option, than i have the CF activ with nice fps, but the screen is flicker. I also try different profiles but nothing work. So at the mom i can only play with one gpu active.
Bad because i play on 4k (30fps).

regards
Chris
