UnitGraph shows very high RHIT on some devices. What is RHIT and how do we make it run faster? Or any other advice about it?
A long time ago (ue 4.7, 4.8) we used to create games with Mobile HDR which runs with 25-30 fps on galaxy s3 - s4. Now it is not possible to get 30fps on galaxy s3 even without hdr… I know it is an old devices and unreal gets more features, but there are very heavy features that have to be turned off. But how?
Hi!
I also found this… problem, and, actually, was able to speed up mobile rendering abit Maybe it will be helpfull for you:
Turn off HZBOcclusion - “r.HZBOcclusion=0”, it eats way too much
If you don’t need occlusion culling - turn it off completely, you will get few additional milliseconds
Use EmulatedUBs - “OpenGL.UseEmulatedUBs=1”
Don’t use textures (especially lightmaps) with resolution > 2048. Just… don’t By mistake i had lifhtmap with resolution 4k, it ate about 10 FPS (42->32).
Check material complexity, you definitely don’t want to have anything red, especially with high overdraw.
For static meshes (if > 2) try to use HISMs, they help alot.
Use only static shadows, try to not use any stationary directional lights, they slower.
Of cource turn off PostProcessing and AA, they will kill FPS.
Using those simple configurations and rules, i was able to get ~32-40FPS on device with Mali-T860 MP2 and fully PBR scene with visible static triangles ~35-40k, and skinned meshes triangles ~80-140k.
Maybe it will be helpfull for you:
