P3d V4 Dynamic Lighting Issue Poss Bug

Recommended Posts

Hi

I seem to have an issue with the Dynamic Lighting in my 777, Firstly I know its a FPS killer and my system (i5 3570K OC 4.2ghz, GTX1050ti GPU,8GB RAM) really cant handle it and reduces my FPS from a steady locked 30 to single figures.

I have switched DL off in the sim which is a huge disappointment as I now have no Taxi lights or RWY Turn Off Light and totally ruins the immersion of flying at night.

Now the DL is switched off in the Sim  all ok with FPS but when I turn on any Taxi lights, RWY Turn Off Lights  etc within the 777 cockpit, I'm still experiencing a huge drop in FPS and not even getting any Lighting on the ground.

Can anybody confirm they are seeing this too, and any suggestions how I can improve FPS with DL switched on in the Sim. I have adjusted lots of settings in the Graphics section but nothing seems to help.

Thanks

Hi,

Not the 777 but I think the problematic is the same:

I have a GTX980Ti and do not see any impact on performance with dynamic lighting.  Others report the same with a GTX970.  This begs the question why your GTX1050ti would event notice?? It's not how PMDG programmed the lighting, one has to suspect something in your configuration.  Just for grins, try a frame rate lock of 20.

There are many who do lock at 20 fps and set the display to 30 Hz refresh rate for amazing results.  I started doing this when I noticed specific cloud types (overcast for example) would kill my frame rate, even when locked at 30, and I discovered the impact disappeared when locked at 24 or less.  So instead of a frame rate dropping from 30 to 14 now it stays steady at 20 and I have smooth animation.

Yes it was a fault with my setup, seems my Graphics Driver was the culprit. I was using 382.33 and have now rolled back to 376.33 and pleased to say all is working well now and holding steady around 30FPS with  Dynamic lighting enabled. I will look into your suggestion  to lock my FPS to 20 and see if I get any improvement.

Many will thank you for reporting that! Glad you found the problem.

I used to get 7 to 11 FPS with dynamic lighting enabled at night over the city. I did the opposite, installed the newest driver (382.53) and am getting a minimum of 30 FPS with dynamic lighting enabled now.

I too am running the newest NVIDIA driver and have zero performance issues. I'm running 382.53.

I think it strongly depends which AA setting are used together with DL on. 4xMSAA or 8xMSAA works good for me, but when it comes to SSAA, I can only use 2xSSA, higher settings results in massive fps drop. Unfortunately, with 4 or even 8xMSAA (HDR on) visuals are not so good (shimmering, flickering, whatever it is called).

Before I updated to the newest driver it made a massive difference what AA setting I used. Now it doesn't matter that much anymore, using 8xSSAA I lose 10 FPS but all lower settings are more or less fine.

I just got some information from one of our devs noting the following:

  • LM asks that all add-on devs compile their projects through the v4 SDK if it is to be used in v4.
  • Related to this, if you are using something that is a simple port over - depends on the avenue the dev chose - the dynamic lighting can cause quite a frame hit: in testing, an older product not specifically v4 compliant had a large hit, while an ORBX v4 compliant airport had little to no impact. For the record, all of our items (models, etc.) went through the v4 SDK.
  • It seems (as others have noted here) that graphics drivers can have an incredibly large effect on this - some are reporting the latest version really helps, while others are reporting that rolling back has helped.

We're tracking all of this to see if we can find some common elements to help you all out.

For me, downgrading drivers did not help, but upgrading to the newest driver 382.53 made all the difference in the world on the 747, no frame drop at all with dynamic lighting enabled and all lights on, 8XSS enabled, 980GTX. Wow, good find, whoever discovered that.

Haven't tried the 747 yet, but going to the latest drivers made the TFDi 717 flyable at night with the landing lights on!

I switched to 382.53 after reading this thread because I thought my 382.33 was causing this problem.  No difference.  Performance okay until I turn on the taxi or landing lights.  I guess something is wrong with the dynamic lighting.  I'm in the 777.

See the post two above yours. Dynamic lighting performance, as LM has set it up, is extremely dependent on your settings.

Yeah, interesting to discover.  For me, it looks like turning off all shadows and decreasing or turning off dynamic reflections altogether seemed to do the trick.  Now I can sit at the "heaviest" airports with the sliders to the right and manage.  I didn't know that dynamic lighting produces shadows and reflections as well.  Interesting little feature in this new verison;-)

Today I installed envtex beta and configured it accordingly. 

When I start up the 777 at night my landing and runway don't light up the run way like they used to.  I have dynamic lighting enabled as well as HDR.  I have the latest Nvidia drivers installed.  I don't think that it was envtex that caused this but I really don't know what could be the cause.

This was the item that changed between it working properly and not working properly. What would lead you to believe that this is not the cause?

I'm not ruling it out but a  friend of mine did the same thing (installed envtex) and his lights are still working.  I will reinstall the 777 and see.

Don't reinstall the 777 unless instructed to do so

I reinstalled this morning and the landing/runway lights are once again working.  During the reinstall, the Ops center complained about some missing textures.  In any case, I am now able to fly and enjoy night time flying.
