i guessed so, i also tried it now with --weightp 0 and no weightp @ all no big speed difference i gonna try now to see when this was introduced by checking all builds between 1222-1342, i missed a lot
PS: it seems the range of the performance drop is somewhere between 1240 (encoded 2419 frames, 9.73 fps, 2941.27 kb/s)-1280 (encoded 2419 frames, 8.92 fps, 2944.83 kb/s)
