My last set of comparisons, this time an interior, same settings as last time (Hardware raytraced lumen, hit lighting for reflections, everything is Nanite, etc., VT is enabled in project, but not used on assets)
Well over a hundred lights in this scene, I set them all shadowcasting to really stress the performance because I wanted to test Megalights. I used VSM for all local lights except in the Megalights capture, in that one they are using raytraced shadows.
Base Scene, hopefully this is realistic enough…:
Measurements:
Edit: Now that 5.5 is released, I tested it again with megalights, best result so far:
Final conclusions:
- GPU performance has improved significantly for me in every version (except 5.5 preview), but not evenly in all types of scenes.
- Megalights will be a big win for performance of local lights for projects able to take advantage of it
Only testing on my own hardware so this is a sample size of 1, and my focus was very much on GPU performance. There have been a lot of changes to physics and skeletal animation that could have big impacts on performance but I didn’t bother investigating that as I’m less familiar with that area of the engine.
Basically… your mileage may vary.
Anyway, thats it, time for me to say farewell to my 5.1/5.3 installs. As always, hope someone found this useful.
