I was testing Nanite. In the built version FPS at the beginning is around 140 and starts to drop down to 15. It happens because utilisation of GPU is also goes down from 100 to around 10. Laptop is Lenovo Legion with integrated and dedicated graphics. What might be causing it?
It happens only in nanite scene. Calling r.nanite 1 restores fps to 140, but after several seconds it goes down again.
Could it be a power plan is set to balanced / energy saving? Is the laptop running on batteries during gameplay or is it plugged in. It may lower it’s clocks on battery power.
Same here did you managed to solve it, nanite definitely has nothing to do with it, I have other scenes with nanite enabled models and everything works just fine on compiled game.
