FPS Drop Low-Level Flying

[DestroyedBeauty]

Flying the Spitfire on the Caucasus map and occasionally when flying low level near trees the frame rate will drop dramatically before jumping back to normal again. Any ideas what might solve this issue?

To much Ai on ground can cause frame drops.

I got everything on High,
visible range extream
Traffic Low
MSAA 4X
Depth of field OFF
Lense effect Flare
Motion Blur OFF
SSAA OFF
SSLR OFF
Grass 100
Trees 50%
Preload Radius 150000
Smoke 5
Gamma 2.5
Anistropic Filtering 16X
Terrain Object Shadows OFF
Cockpit Global Illumination ON
Rain ON
Vsync OFF
My Resolution 2560x1080

morphological anti aliasing need to be OFF, you can find the setting in your graphic card driver

I got a similar system, you shold got a frame range 50-100 FPS with this setting, or even more with your CPU.

My specs i7 6700K 4.5 Ghz, RX 5700 XT OC, SSD, 32GB RAM

Tell me how much frames you get.

Deleting the shader cash can help too.

There is no morphological AA in Nvidia Control Panel. Maybe you're referring to FXAA?

Thanks for the replies.

The problem I think lies with the Static weather model and cloud density being set too high. Subsequently found out the Static WX model isn't well optimised, which is a shame but I'll work something out.

Yep. 100%. If you set cloud density to 4 or less, you will get a significant FPB improvement compared to 5-8.
