dynamic lighting is THE fps killer

Recommended Posts

Enabling it will drop performance from 70 fps to a slideshow (15 fps) at TNCM from FlyTampa... amazing.

Plus, I am not fully convinced by the effect : my default Mooney was flooding the default AI A321 (parked 100ft away)  like a football stadium  :-)

I get decent performance with dynamic lighting if I limit to 2x or 4x MSAA, no higher.

Ssgs will screw your performance..Brings mine from 100 fps to 40..I use 2x msaa

Plus imo, MSAA 4x is very acceptable at night, not so much shimmer, especially shadows, since they are not so obvious at night.

my sim crawls with the box checked for terrain shadows. if i keep only clouds and my aircraft I can max all sliders including autogen.

For me it's 8x vs 4x SSAA.  That made a 30% fps difference.

but yes I noticed in some planes turning on landing light or taxi light will light up the entire cockpit.  This happened on P3D v3 planes like the XPLear 25.  Then my fps tanked.

Is MSAA new in V4 ? Or it's a different AA scheme now?  Sorry I don't have V4 yet.  Thx

SSAA is new in v4

MSAA is the original method from earlier versions but still available in v4

What is the best AA setting? Is it in P3D or N-Inspector? Or which is acceptable when considering performance (fps drop).

I like the dynamic lighting, but I would be willing to turn it off for performance sake. From what I remember in P3D v3.3, the Orbyx night light was pretty decent for my tastes.

Supersampling might be a nifty way to get rid of jaggies, but it comes at a high cost when we're using high screen resolutions to begin with. SSAA basically draws the screen at multiples of your selected resolution and then down samples it to your screen resolution. So 4xSSAA is rendering the graphics for a 2560x1440 screen at 4X! that resolution and then down sampling. Yikes!  

MSAA has a cost as well, but I think produces the best results and is the newer technique. I find that mostly I don't see a big difference at anything over 4xMSAA.  I don't see the point of using both  

I don't use FXAA, as post process AA is inaccurate. 

I think using the programs AA is better if it is an option.

I have P3Dv4 ver4.1 What is Dynamic Lighting? I can't see differences when is On/Off. Is Dynamic Lighting for night time? Also, when I rotate the view, the airport lamps posts turn on and off depending of view panning. Is this dynamic lighting?
