0 = sRGB (LDR) (default)

1 = Rec709 (LDR)

2 = Explicit gamma mapping (LDR)

3 = ACES 1000-nit ST-2084 (Dolby PQ) (HDR)

4 = ACES 2000-nit ST-2084 (Dolby PQ) (HDR)

5 = ACES 1000-nit ScRGB (HDR)

6 = ACES 2000-nit ScRGB (HDR)

r.MobileContentScaleFactor

This controls how the content will be scaled when it is on the device. A setting of 0 will use the native resolution of the device. If you are using a DPI scaling curve for UI scaling, make sure to set this to 0.

r.ParticleLODBias

This controls which particle LOD will be displayed. 0 will use the base, while 1 will use the first LOD, 2 the second LOD and so on. In Unreal Match 3, only the first LOD was used to cut the amount of particles spawned in half on lower-end devices.

sg.EffectsQuality

This controls the spawn rate of the particles per tick. It ranges from 0 to 3, with the default value being 3. Lowering this number will result in fewer particles being spawned per tick. Setting this to 1 will result in particles being very sparse and is only recommended for extremely low-end devices. Setting to 0 will stop all particles from spawning entirely.

fx.MaxCPUParticlesPerEmitter

This controls how my CPU particles can be emitted per emitter.

There is my Note 9 extreme low settings without overheating/throttling and stable 60 fps
