FPS In A Threesome Scene

[BritishScenes]

Hi guys,
I am creating a threesome scene and I am struggling to keep it above 30fps, ideally i want it to be smooth 80fps for VR.

I have used the givemefps plugin to disable hair physics and also glute physics.

it is currently in a custom environment, would I better with a blackout environment (like the default scene) ?

Any other tips for maintaining fps specifically with a threesome scene, I get 3 person atoms will make the engine struggle.

There more under the hood than just physic, hair quality can also affect fps, in look tab of hair you can see if changing shader type do something, hair density and multiplier also. Light, check the shadow quality and how far it reach, can also affect performance. Environment is hard to tell, there no way to know about texture file size and the useless amount of polygone, there is definitely some environnement on the hub, that are very poorly optimized.
Hope you get more advices, personally I have 80fps threesome in vr, but it is far from been stable.

Are you talking desktop framerate? 'coz if you're at 30fps with 3 chars, it's quite low, you probably have everything enabled (like soft bodies for instance).

If you have 30 fps with pretty much everything disabled. Then the enviro is potentially at fault, or the way you light it.
A proper enviro should be a "zero" footprint on your scene. If you prefer, when I'm making enviros, I'm ensuring I'm getting pretty much the same framerate as you have when the scene is empty (which is around 350fps), and for very very intense enviros, I go for at best, 250fps when the enviro is loaded in.

To test it, empty your scene, keep only the enviro and your lights. Check the framerate. Then disable lights. Check the framerate.

If in both case you have proper framerate (so as I was suggesting, between 250 and 350fps), then you're good, and your problem comes from your choices on the characters ( soft body, hairs, clothes, etc ).
Note that physics have a base overhead when idling, but that overhead increase animated. If you're doing the 3some with all three characters having heavy animations, it is quite intensive.

thank you @hazmhox for your detailed reply, and information, I believe it is the person atoms, without them the scene and lighting is giving me good FPS, so suspect too heavy on the hair and soft body, will bring it down to suit the scene.

thanks again
