SXM Performance Drop Mid Runway

Post by sfgiants13 » Mon Jul 31, 2017 7:22 pm

I'm having an interesting problem that I'm trying to get sorted. Throughout my entire approach, I get a smooth experience running 25 FPS at unlimited using vsync on my monitor set at 25hz. It seems once I hit the numbers, my FPS drop quite a lot and I get stutters due to my FPS no longer matching my monitor refresh rate. That continues as I go down the runway even once I'm past the terminal and staring into the mountain. Once I turn around and head back to the terminal my FPS rebound and smoothness comes back. I'm just curious as to what could possibly cause this big drop in FPS especially once I'm no longer staring at what should be the most demanding area of the scenery? I run a 6600k at 4.4 with a 1060 GPU. My AA is at 4x SSAA which doesn't help but at most airports I can maintain good performance (ie: AMS gives me no issues but DXB for whatever reason is a bit harder so I have to drop my AA). If I stay at 8x MSAA performance is good throughout, but I get a lot more shimmering so I prefer not to run that. My settings are pretty middle of the road otherwise for things such as autogen. I have all options in the config tool enabled except the people both of which are disabled. Is there a certain part of the scenery that's more of a hard hitter on the FPS than others?

Any ideas would be appreciated.

Sorry I forgot to specify this is for P3D V4 with the latest updates installed.

Its best if you test this in slew-mode (press Y). If the FPS slow down every time you look a certain direction there maybe "something there" thats causing it. If on the other hand the fps drops at first but then you look some other direction, then go back over the runway and fps is fine, it would indicate that it was perhaps just "loading something" during the initial slowdown.
