Abburo Posted October 1, 2015 Share Posted October 1, 2015 My SLI looks like is not fully used. One GPU goes to 98% while the second one remains on 10%. My PC details are in the signature.

pgh2atl Posted October 1, 2015 Share Posted October 1, 2015 I'm using a 295X2 & Crossfire seems to be working....which is the first time EVER with this sim. Both GPU's running at 100% working great! My only issue is that the memory on the second GPU doesn't seem to ramp up. Stays at desktop levels (150mhz) compared to the first GPU level (1250 MHz). Anyone using a 295x2 having the same issue?

JPS2K Posted October 1, 2015 Share Posted October 1, 2015 Same thing here. 2x 980Ti and no matter what setting I use for Nvidia control panel, 2nd card is NOT being used... Link to comment Share on other sites More sharing options...

JPS2K Posted October 1, 2015 Share Posted October 1, 2015 It must be the lack of a sli profile for the edge engine, only way to get around that is to change sli profiles for this game via nvidia inspector. Change it to some other dx11 game and experiment. Previously the windows assessment tool profile worked best for my 980 sli in nvidia 3dvision so maybe try there. Surely it has nothing to do with the profile, since I'm setting my settings by hand, therefore not using a profile ? Link to comment Share on other sites More sharing options...

In DCS World, I can only get SLI to work using Nvidia Inspector. There seams to be either a lack of a profile, or lack of ability to get the blackshark inspector profile to work with openbeata.

Sn8ke Posted October 1, 2015 Share Posted October 1, 2015 Well all you have to do is add the 1.5 exe to the existing dcsworld/black shark profile in nvidia inspector.

JPS2K Posted October 1, 2015 Share Posted October 1, 2015 Yeah, I manually set the GPU count and it works. Not sure how well it works yet, since I still need to put away my steering wheel and setup my flight gear again. But it's using both cards...

JPS2K Posted October 1, 2015 Share Posted October 1, 2015 (edited) Ok, I never used Nvidia Inspector, so I downloaded it, opened it, and at 'Number of GPUs to use on SLI rendering mode' I altered the drop-down to the right of it to 'SLI_GPU_COUNT_TWO' and then right top corner Apply settings... Ow, and afterwards I found the home icon left top, I selected 'c:\program files\eagle dynamics\dcs world openbeta\run.exe' and saved that profile, since I don't need my system to SLI my desktop:pilotfly: Edited October 1, 2015 by JPS2K Link to comment Share on other sites More sharing options...

Anyone using a 295x2 having the same issue? My Crossfire 2 x R9290x is only working on the primary, nothing on the second card. (EDIT: This was before we all found out it was running in Borderless Window mode by default) Did you set anything in the CCC to get it to work? I think you'll find that until DirectX 12 only the memory on the primary card is addressed. (This has always been the case for both SLI and Crossfire.)

Sn8ke Posted October 1, 2015 Share Posted October 1, 2015 Card two is used, but pnly 1-2%, which is why i believe there is a significant performance gap, expecially compared to the current release dcs world where the card is humping at 12-17%, giving me a steady fps of 60.

I think you'll find that until DirectX 12 only the memory on the primary card is addressed. (This has always been the case for both SLI and Crossfire.) Just noticed that while the second card is being utilized at 100% (per MSI Afterburner) my gpu clock & memory never change from desktop speeds (300 MHz gpu/150 MHz mem). But I'm getting decent fps (never drops below 42fps) with everything on high in Eyefinity (5760x1200) so I'm happy with for now. Man....but if I can get that second card to kick in.....that would be sweet! Link to comment Share on other sites More sharing options...
