I think that might be the issue. Lumen + many lights = high drawcalls.
@jblackwell I tested with profileGPU. I don’t think its a gpu issue. Day & night are almost the same in frame time.
day scene: 41ms27, shadowdepth 6ms18, lumenscene 9ms42, diffInAO 12ms98, lights 1ms45, translucency 0ms98, ppv 3ms89
night scene: 46ms06, shadowdepth 4ms24, lumenscene 9ms07, diffInAO 14ms35, lights 6ms67, translucency 1ms17, ppv 2ms55
The difference in day & night is due to the spot lights.
I did see a drawcall difference between day& night: 315 vs 1958 so I’m investigating th…
Soryy for the late reply - your post totally escaped my attention. I haven’t found the cause. Activating RRCulling doesn’t do anything. Just did a new test - some objects were added to the scene since my last post though;
Day-GPUlightmass: 667 drawcalls
Day-Lumen: 1035 drawcalls for 5 moveable lights: 1 directional, 1 sky and 3 pointlights
Night-GPUlightmass: 650 drawcalls
Night-Lumen: 2975 drawcalls for 47 moveable lights (insane I know - just for testing Lumen)
As for a CPU bottleneck, I…
