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


Recommended Posts

Posted (edited)

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 :detective_2:

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.)
