The speed feature "disable_smooth_intra" has no time saving while introducing coding loss at speed 3, RA:

Speed3 PSNR-YUV EncTime
A1 (17 frames) -1.28% 99.14%
A2 (33 frames) -0.88% 100.34%

By disabling the feature, we recover coding gains without noticable slowdown.

Nice finding. Is this 17 or 33 frames test?
