So the "realtime GI" is just pre-computed?

Development Rendering
4

Alright, that looks promising :slight_smile:

One more thing, an issue related to rendering that I am having right now.

Any idea why my GTX 580 is hitting 52 C for a blank scene like this?

My GPU typically idles at 33 C when no games are running.
And if I play games on lower graphics settings or older games, the temps are typically 38-45 C

For comparison, I get 45-50 C in DOTA 2 on highest graphics.

Or 55-65 in a game like Alien Isolation on highest graphics

UE4’s frames are limited to 62 FPS

So by comparison, you can see why I’m a bit concerned :stuck_out_tongue:

I am trying to switch over from Unity, and this is really the last thing that is really keeping me from making the switch.
Everything else about UE4 seems superior to me, but performance is definitely very important and I need to have confidence in UE4’s optimisation and performance.

I want to figure out what element remains costly even in a black void with a grid so I can determine if its necessary and can be disabled.
