I did a night flight with the Falcon and noticed when switching on the recognition lights it completely saturates my GPU if I am using anything higher than 2x SSAA. Taxi lights, landing lights, nav lights, cockpit lights all seem to have little effect, but switching on the recognition lights kills my GPU.

Seems strange because from the virtual cockpit views it's impossible to even see the recognition lights, or anything that lit by them. Normally if I'm noticing heavy GPU use in areas with dynamic lighting, if I simply pan the view so those lights, or any objects lit by them are out of view, my performance goes right back up.

Kind Regards,

The Falcon does not have recognition lights. It does have emergency lights that shine on the ground in front of the wing. We did update this light and it seems fine to me. So can you describe or post images of the light that kills you gpu. So far not other reports of light issues.

Oddly enough I have had a dynamic lights issue, although this may have no relation to the "recognition lights" issue here.  (That's what they are called on the overhead panel, I think).

Occasionally I have had the landing lights and taxi light beams suddenly vanish when viewed from the VC.  When viewed from an exterior side spot view the light beams are visible, but when I swing the viewpoint to behind the aircraft, looking ahead, the beams then vanish the same as in the VC view.  Weird.  I haven't had time time to investigate this any further, and it doesn't happen every time anyway.   I'll see if this is something I can replicate at any particular place in my add-on airfields.  The lights do generally return, I think, but not on the last occasion.

It wouldn't surprise me if the P3D4 dynamic lights code had the odd gremlin lurking in it...

" The Falcon does not have recognition lights."

Then nobody informed the Falcon that it's not supposed to have recognition lights, because the switch label says "Recog"

From the Falcon 50 manual:

"RECOG (When forward the wing/ground recognition lights turn on. Located in front of wings on both
sides.)" Notice "recognition" above.

And THIS is the light that kills my GPU.

Kind Regards,

SSAA ist the culprit. Dynamic lights and SSAA don’t play well together. I think LM never solved that. 

Sorry yes the F50 shares the same light for the recognition and the emergency exit lights. But for your issue it must be something like what Mad_X posted as it not an issue for our customers.

I know and understand well the burden of dynamic lighting, and that it is especially heavy when using SSAA. My point was that from the VC the recog. light really can't be seen but still exacts a heavy toll on performance. It just seemed strange to me that the recog. lights would be a higher burden than either taxi light or landing lights, both of which from the VC you can see illuminating objects and the ground. In my experience when DL's are illuminating objects in the field of view, the performance demand is almost always dramatically higher than when the same illuminated objects are not in the field of view.

Kind Regards,

I guess I am the odd one out here, but whether I choose SSAA or MSAA my FPS is not affected. That is with a GTX 1070. Unless there is a bug with a particular aircraft, it does seem the dynamic lights issue is not nearly as bad as it was when P3DV4 first came out.

Steven what is your video card?

I pretty much don't run SSAA at night at all, because of the performance hit, and I run a 1080ti.   My night settings profiles use 8xMSAA.
