Rain performance

[HoBGoBLiNzx3]

I have an i7-9700k, 32gb, SSD, 3080, and a Reverb G2. Have medium to highish settings. Get an avg of 50FPS during the day and on carrier. 

However, with rain I'm getting huge drop in frames (10-25fps and 10ms) 

as a side note at night I also lose 10fps and I seem to have a layer of odd mesh lighting when I zoom in (on PG) it almost looks like a fulstrum culling issue with the new lighting (even though I have it off) 

Obviously, I can't produce this with a track as it's not duplicated via VR mirror for the lighting, and for the weather I can't see how a track would help as it will give you the exact same numbers I just gave you from load to exit. 

I drop less frames running 4x MSAA than having rain on a mission... esp at night. It's like 30fps hit.

What resolution are you running on the G2 and any XRtoolkit settings

 

resolution is a key thing I have found on my 3080ti

80% on OXRT and 80% Sharpening on CAS (with FFR on custom)

It's not my frames, I get good frames during the day even on larger online missions. It's night time and rain that just kill my FPS for some reason. ESP rain on the carrier and I'm at 20fps from 50-60. That is without secondary shadows. 

Shadows = high

Terrain Shadows = Flat + Blurring 

Terrain Textures = High

Textures = High

Distance = Medium

Traffic = OFF

MSAA = 2

AF = 4

CP Illumin = OFF

Reflections = Dirt 

(everything else is pretty much off) and I'm very generous on the sliders as well.... As I've tuned it pretty well for heavy missions and online play.

Turning down the clouds from ultra to high seems to have resolved my bad rain performance. Not sure if that just made my game marginally stabil or if that parameter also scales back some of the rain related graphical effects. Could be coincident, but might be worth a try.

I’m not flying in VR but was recently a bit disappointed that my i7-12700k/3090/64gb ram was getting stutters in the Syria map flying the Apache over Al-Raqqa during sunrise with all settings on high when everywhere else and all other maps were not an issue.
 

Found with aircraft testing that the Apache seems to use about 15-20% more resources than any other aircraft at same location. 

I recently upgraded to the i9-13900k and experimented with several settings and found that by leaving all settings maxed out but turning shadows from high to flat only stopped all stuttering and actually gave my 3090 some extra headroom while strangely pushing my CPU from average overall usage of 25-30% to about 40-45%. 
 

So maybe try just turning shadows off.
 

I guess only a 4090 will run DCS at its absolute bestest.
