Dynamics lighting brought my GTX 1080 to its knee

DL might be more impressive down the road, hopefully with Nvidia GPU's post Pascal. I'm waiting for Volta, or beyond, before upgrading my 970. 

+1

Consider getting a second 970 cheap and go SLI if you must. There is quite some advantage in bad weather ,resolution ,shadows etc .

I am only SLI now as long as i dont use any 3part external FMC (VR CDU-II) 4K

I simply turn Dynamic Lighting off.  If your scenery was not designed properly, turning this has the effect of lights from scenery shooting in all direction and destroy any optimization that LM can come up with.  A scenery developer told me that as soon as he enabled dynamic lighting his scenery performance reduced by 2/3.

Well, then you have basically the only two options deactivated that really make an optical difference between P3D and FSX. What is your FPS aim? 60 FPS? Otherwise I do not get how you limit your settings that much with such a capable system as a basis...

Hi AnkH,

i just did again a few test with DL enabled. Test scenery was FSDT KIAH and FB KIAD aircraft in use PMDG T7 and default Beech Bonanza. Below you find my settings within P3D[6]4. Autogen trees and building casting shadows were also enabled but dont like it when in an airliner however it didnt make that much of a difference in performance. I also installed nVidias latest driver. Im using two tweaks within the cfg 1. TEXTURE_SIZE_EXP  2. JOBSCHEDULER=340. AS16 delivered the weather, MT6 gave me the AI and Chaseplane let me look around the cockpit.

My system as mentioned oc´ed i7 5820k @4.5 GHz 16GB 3000 MHz GSkill Rip Jaws ASUS GTX 1080 Strix Advance dedicated 1TB SSD for P3D[6]4 everything plugged onto an ASUS Rampage V Xtreme Mobo. Within my bios i enabled an XMP profile.

@KIAD i flew around shot a few low passes with the T7 with landing lights on the frames were nearly constant 30+ in the vicinity of the airport scenery and a few more FPS ≈35-40 when over ORBX openLC US+Global+Pilots FS Global Ultimate NG mesh

@KIAH the story was slightly different the frames hovered between 26-29 over the field and flying outside the KIAH 30+

In both situations the bonanza obviously gave me more FPS than the T7. However P3D[6]4 feels smoother when frames below 30 than P3Dv3 at least to me.

Try wih MSAA instead of SSAA

 

Michael Moe

I agree with Michael.

 

Any SSAA setting in p3d v4 hammers frame rate with dynamic lighting.

I see the same symptoms with my 1080  with just one 1080 monitor.

I use either 8 x MSAA in sim, or a combination of 4 x MSAA in sim with nvidia inspector set to enhance application aa and choose 4 x sparse grid SS.

 

The latter provides pretty good results for me, with no difference in frame rate with or without dynamic lighting.

 

My Spec below.

 

Happy tuning

Could very well be SSAA which hammers performance for people. I use MSAA and have little to no performance hit... (i7 6700HQ, 1060 Graphics)

I seem to have very good performance in SLI with Dynamic Lighting on and SMAA x2 ,4K but sitting at FB , KSFO RWY 28L looking down the PFD, and ND in the PMDG747-400, 777LR degrades the performance very badly. Both GPU goes way beyond 100%

Did not test with terrain Radar off but can anyone interested try the same ?

FSDT KJFK runway 22R and no issues what so ever

Thanks

That CPU better for rendering and for the computing. Not for gaming. For P3D the good processor's whiches for gaming.

So what qualities does a good CPU for gaming have?

The massive GPU impact stems from the p3D v4.x code rendering the dynamic lights, way further out than they are actually set to be visible.

Perfect example of this is in the PMDG B744. While a single landing light only creates a light splash visible 80-100m from the aircraft, the sim is rendering (doing the math) up to the maximum distance.

If you play with the SDK's Light FX add-on, you can create a light that illuminates a object 4000m out. Yet if you reduce the illumination to only 10m out, the FPS impact remains the same. So in summary, our GPU's are faced with rending lights to distances much greater than they are set to be visible. 

LM is aware of this (thanks to developer reports) and it will presumably be fixed in the first update!

 

Glad to hear that! Because I can't fly without DL on the planes at all.

Ehm, what?! I suggest you google a little bit for the differences between the Intel CPU's. Just as a hint, the so called "rendering" CPU you are talking about is an Intel i7 4960x, basically an Ivy Bridge 6 core CPU. And while it is optimized to be used for "rendering and computing", it is basically just an i7 3770K with two additional cores. And the i7 3770K you would consider as "gaming CPU", no? So what? Because of the two additional cores? Because it was expensive? BTW: the 4960X also has a free multi, meaning you can overclock it (like the 3770K) to 4.5GHz or beyond. The single core performance of both 3770K and 4960X are basically identical, no surprise, as both are based on the Ivy Bridge architecture. So, NO, it is not possible to say that the 4690X is "not for gaming", that's ridiculous.
