HUGE FPS LOSS WITH RAIN ON (latest beta 2.7.1.7139) even it is invisible

[Gryzor]

When RAIN is enabled, even it is invisible (bug in latest patch), it makes a big FPS hit (in VR, with an average of 4ms more ...for example, from 13ms to 17 ms... -30% in performance). Please traslate to the DEVS. Thanks.

I made a small test with an empty mission over Caucasus and different SSAA and Clouds settings. Results are pretty interesting:

 

Clouds on ULTRA - SSAA x1.5 : rain setting has an huge impact on FPS (-33%)

"Nothing" : 100 FPS - "Light scattered 2" : 90 FPS - "Overcast 7" : 85 FPS - "Overcast with rain 2" : 66 FPS

 

 Clouds on HIGH - SSAA x1.5 : rain setting has an huge impact on FPS (-28%)

"Nothing" : 100 FPS- "Light scattered 2" : 90 FPS- "Overcast 7" : 88 FPS- "Overcast with rain 2" : 74 FPS

 

Clouds on STANDARD - SSAA x1.5 : rain setting has an important impact on FPS (-21%)

"Nothing" : 100 FPS- "Light scattered 2" : 90 FPS- "Overcast 7" : 90 FPS- "Overcast with rain 2" : 79 FPS

 

Clouds on LOW - SSAA x1.5 : rain setting has an important impact on FPS (-20%)

"Nothing" : 100 FPS- "Light scattered 2" : 90 FPS- "Overcast 7" : 90 FPS- "Overcast with rain 2" : 80 FPS

 

Clouds on ULTRA - SSAA off : rain setting has a moderate impact on FPS (-10%)

"Nothing" : 120 FPS- "Light scattered 2" : 120 FPS- "Overcast 7" : 120 FPS- "Overcast with rain 2" : 108 FPS

 

Clouds on HIGH - SSAA off  : rain setting has no impact at all on FPS (0%)

"Nothing" : 120 FPS- "Light scattered 2" : 120 FPS- "Overcast 7" : 120 FPS- "Overcast with rain 2" : 120 FPS

 

Clouds on NORMAL - SSAA off  : rain setting has no impact at all on FPS (0%)

"Nothing" : 120 FPS- "Light scattered 2" : 120 FPS- "Overcast 7" : 120 FPS- "Overcast with rain 2" : 120 FPS

 

Clouds on LOW - SSAA off  : rain setting has no impact at all on FPS (0%)

"Nothing" : 120 FPS- "Light scattered 2" : 120 FPS- "Overcast 7" : 120 FPS- "Overcast with rain 2" : 120 FPS

 

Important note: results may be different once we will get back precipitations visual effect.

I also made some tests, in order to understand my system a bit better.
Since I am on low specs, I have to carefully read these sections of the forum

Today, I was looking for fps on my 1920x1080 screen, not VR.

GFX: Nvidia GeForce 1070, Intel 6700 4,5GHz, RAM @3000MHz, 32GB

 

1.) Scene in Creech/Nevada in spectator view that shows up when starting the mission:

    Rain droplets OFF:    "Overcast + Rain 2":     92
    Rain droplets ON:     "Overcast + Rain 2":     92
    Some more cloud presets using this scene:
    Rain droplets OFF:    "Overcast 2":            105
    Rain droplets OFF:    "Broken 2":              105
    Rain droplets OFF:    "Scattered 2":           107
    Rain droplets OFF:    "Light Scattered 2":     107

    Rain droplets OFF:    "None":                  126

 

2.) Now with F-15C as pilot and cold on ramp at parking position A01, looking South (not comparable situation with the one above!)

    Rain droplets ON:     "Overcast + Rain 2":     69
    Rain droplets OFF:    "Overcast + Rain 2":     75

 

Rest of the settings see below, and one reference screenshot for 2.)
