SLI -Profile for 353.06 (2x970SC) ?

[Michael Moe 494]

Just installed my two 970´s and cant find a thread regarding SLI configuration for P3D2.5.

 

I did try Rob´s page but could not find information for P3D2.5

 

Also i cant find a Sli Profile in NI that mention P3D.?

 

Maybe Rob also has one for Project Cars now that i do believe he is a racedriver :-) ?

3 Questions

 

1. Should i connect all my monitors to one card? or spread them between the cards ?

 

i have 

 

1 x 1920x1200 Hanss G 28"

1 x 1280x1024 (just for PFD,ND)

1 x 1024x768 CDUII via an displayadapter(active)

 

 

 

2. Does SLI also work in Windowed Mode ?

 

3. Any benefit of using Dynamic Resolution (upscaling) here ? (guess i have to disable the CDUII and the 1280x1024 first)

 

Thanks for your help

 

 

 

Oh last my activation for P3D has reset because i upgraded so it gives me an error 13 code . I have sent them an email.

Hi Michael,

 

  I have almost the same hardware like you .

• SLI 2 x 980 GTX
• Monitor for Prepar3D 42" (1920 * 1080)
• Monitor for Aivla, vpilot etc 27" (1920 * 1080)
• Monitor for FMC 10" - CDU II

1. I use profile for NI - http://www.robainscough.com/P3D_SLI_Settings.html

 

 

 

 

2. All my monitors are connected to one card. I think that is the only possible configuration - I mean SLI active with 3 monitors

 

3. With all 3 monitors , i dont have DSR option active in Nvidia Control Panel

 

 

Best reagards,

Nicu

Thanks. What version of the driver are you using? 353.06 does not show P3D SLI information/combatibel

 

Thanks Michael

[NicolasTAP 6]

353.06 and show P3D SLi Info. Just click on line

 

[Michael Moe 494]

No P3D mentioned here. Strange

Between Lichdom: Battlemage and Far Cry 4. That setting is what nVidia uses to trigger app-specific behaviors  in its drivers under SLI.

[Michael Moe 494]

Nope not in my driver and NI as i said .Strange

Looks like you forgot to uninstall the previous driver before installing the new. Some drivers cannot be installed over the top of the old.

[Michael Moe 494]

No i uninstalled via ddu in safemode before i changed the cards so Strange.

Did you select the P3D profile and then RESET to default after installing the driver?

If you don't do the "clean install" checkbox when installing a new driver it preserves all profiles and does not update them at all. Rerun the installer and pick clean.

[Michael Moe 494]

Ok will try that

 

I always uninstall via DDU in safe mode first

 

Thanks

Okay after a re-install of the driver (clean install) i now have a P3D profile in SLI

 

But it seems i have lost 12% in terms of FPS going from GTX780SC to SLI GTX970SC . (Gate A20 EKCH 45fps before now 38)

 

That sucks :-)

 

Anything i should try ?

 

The GPU usage is in Precision X with my older settings is GPU 1 30-34% GPU 2 32-36%

 

Thanks

 

Michael 

 

 

Update:

 

Disabling SLI i am at 44FPS (almost as goodt as my GTX780SC) and GPU usage at 46-51% so any ideers what i am doing wrong here ?

 

Project Cars shows an increase of 10% with 1-vs 1 and 25-45% increase in SLI vs 1 GTX780SC

 

CPU I7-4770K@4,6GHZ at 39.50% usage

Michael,

   Try to fly without  Precision X

Michael,

   Try to fly without  Precision X

 

 

Thanks i will give it a go,

 

But when i undock my PFD and put it on my second monitor the fps is now cut in half. I have Vsync on and i did not have this problem with my old GTX780SC and the card before that either. Normally it would cost me 2 fps undocking.

 

What am i missing here ?

 

Thanks

Michael Moe

 

 

Update: Hmm just undocking (not moving)and my FPS is really bad (4-5 fps). Thought it was the 59-60HZ thing so i desided to change every monitor to 60HZ but still the problem.

 

Also tried with no vsync but no luck .

 

Will try with only one card again.

 

Could be related to SLI out of SYNC ? ALT-Enter fort and back does not work either

 

I run windowed mode as i want to undock my CDUII etc.
