Dynamic Lights - Not just FPS

[aceridgey 330]

Hi all, just wanting a santiy check here.

 

Specs 6700k @4.5 GTX980ti 16GB ddr4 ram, SSD.

 

Now we're all talking about how much dynamic lights destroys FPS which I can relate to, partiucularly in the 747. Not so bad in the 777 but what I have noticed is that for example, uk2000 egll, dynamic lighting on at night:

 

The fps decreases 10-30% but there is a notable 'lag' introduced, even at 35fps there is a hang time between moving my virtual head around using Chaseplane for example so I don't think it is a just an FPS problem but something deeper.

 

Thoughts ?

I believe there is an issue with scenery add-ons that aren't built with the P3Dv4 sdk having a dramatic effect on fps with dynamic lighting.

Hopefully as scenery developers start releasing add-ons built purely with the v4 sdk we will see an improvement in performance with dynamic lighting.

It's not uncommon once you completely max out a GPU, that it'll start to feel delayed and juddery because there's absolutely no wiggle room for preparing frames or having them spit out in a fashionable timeframe. Dynamic Lights can eat up GPU cycles for breakfast. When I enable Dynamic Lights + 4xSSAA, sitting on the ground, it's not uncommon for my 1080 Ti to be completely maxed out and I get the same sort of delayed, sluggish feeling.

Thanks for your replies,

 

Gordon, I am starting to think this whole scenery thing is greatly exaggerated as this happens for default and in the air.

 

Michael, ok, I only have 4x msaa and still struggle massively.
