StrmnNrmn vient d'annoncer avoir résolu un bug important et ainsi avoir gagné quelques images par secondes de plus. Il estime le gain entre 20 et 25%.

Pour illustrer son annonce, il a proposé un tableau de progression avec le jeu Super Mario 64:

Scene R4 Framerate (Hz) R5 Framerate (Hz) Current Framerate (Hz)
Mario Head 3 6 8
Mario Main Menu 14 25 30
Mario Peach Letter 6-7 11 13
Mario Flyby (under bridge) 6 10 12
Mario In Game 5-6 9 11
Mario Kart Nintendo logo 10 23 24
Mario Kart Flag 6 11 13
Mario Kart Menu 7 11 13

Il nous promet un tableau identique avec Zelda et surtout une implémentation de ce debugage dans la R7.


Annonce originale:

I'm very pleased to be able to say that I've finally managed to fix the nasty bug I blogged about on Thursday.

I'll go into more details in a later post, but in essence the problem was due to very rare situations where the trace recorder would exit a trace when there was still a branch delay instruction pending. This caused the fragment generator to inadvertently skip the branch instruction, causing the odd behaviour I was seeing.

For reference, here are some updated figures for Super Mario 64 and Mario Kart (initial results are from a previous post). Generally the current changes seem to indicate an overall speedup of 20%-25%, which is great for a few days work. What's even better is that I've still not implemented all the optimisations that I have planned for R7, so hopefully these numbers will look even better soon..
