Lumen GI is slower in 5.5 preview
I’m talking about .40ms slower at 1080p
I have a set of testing commands for Lumen, it’s basically a modified high version with slow update(best possible performance and TAA independence).
In 5.4, I can get around 2.1ms
In 5.5, I can only get 2.6ms
(EDIT: In 5.3, 1.8ms and 2.6ms if directional light is disabled?)
These are the timings I got after confirming CVARs actually improved performance(for instance async or HW support in different versions does not boost performance).
Almost .50ms on 12 teraflop hardware at only 1080p and you guys no competent temporal reprojection, constant noise from motion or disocclusion.
Hopefully this is just a preview issue. Because 5.4 GI was also much slower than 5.3 and again, same issues are present and it’s issues consumers and developers have been criticizing for seasons now.
