    psp Daedalus PSP R9 Speedup Details -N64 Emulator for PSP WIP News

    StrmnNrmn posted this news on the latest of his work on the Nintendo 64 emulator for the PSP

    In my long-overdue update on Thursday I explained how some of the work I've been doing on the dynarec engine has produced a significant speedup. This post will give a few numbers to give an idea of what you can expect in R9.

    The table below shows the framerate for various scenes in R8 with a column showing the framerate for the build I'm currently testing effectively R9). The final column shows the relative speedup:

    check out the the screenshots comparing r8 and r9 to certain games visit the website there is also another update before this.

    Clearly there's a significant improvement in framerate. On average, games are running about 40% faster, but in many cases the framerate has almost doubled. Subjectively, the difference means that many games are feeling a lot more responsive and playable now. Anything over 20fps 'feels' pretty good, but my long-term goal is to get this up to 30fps for as many titles as possible.

    I noticed a couple of interesting differences between the two builds when running the tests, and you can see some of these in the new screenshots. Firstly, notice that the shadows in Super Mario 64 are all nice and round. This is due to the 'mirrored texture support' that I mentioned in Thursday's update (this also fixes the star that opens over Mario's head in the title sequence).

    Secondly, the jerky/shaky screen that was affecting Mario Kart 64 now seems to be fixed. I'm not quite sure what was causing this, but I'm glad it's fixed

    Next, notice that the text is Quest 64 is now fixed. In R8 this was horribly corrupted. This is due to the fixing a few texture conversion bugs as I was introducing proper support for 16 bit textures.

    Finally, the texture on the floor in Quest 64 is now fixed. Again, I'm not totally sure what change is responsible for this, but it's nice to see it working correctly.

    One final thing to note is that these figures were obtained by running the emulator with 'optimal' settings. For the current build, this includes disabling audio output. I'll talk a bit about audio support soon, including a bit about its impact on performance.
