Can TPT run on the new RPi 4?

    I can't find any specifications for TPT when it comes to peformance. I am setting up a RPi 4 on my workdesk and I want to know if it'd be possible to run TPT on it, as it's going to be a development device.

    I once compiled TPT on raspberry pi 3 b+. It is quite lag for common saves tho, like around 20 FPS.
    I haven't bought model 4 so I can only make some prediction here.

     

    Here we look at the most significant difference.

    RPi 3b+ has

    • quad-core 1.4GHz CPU (affects simulation speed directly)
    • 1 GB RAM (size only matters if TPT is using all the memory, but it is not)
    • GPU Broadcom Videocore-IV (affects screen rendering)

    RPi 4 has

    • quad-core 1.5GHz CPU
    • 4 GB RAM maximum, and faster
    • GPU good enough to handle one screen output without performance loss

    There is slight upgrade from all aspect if you look at the numbers.
    Usually such all-rounded upgrades would solve a few system bottlenecks,
    the final effect depends a lot, you need to try yourself.
    You can expect up to around 30 FPS, I would say still quite lag for human users.

    The compilation guide is not updated as often as the repository,
    there might be problems but it should mostly works.

    It can be compiled on the RPi4 (use the linux compilation guide) with this flag when building: --no-sse.

    Like so:

    make -j4 --no-sse --release

    (The flag --release is inperitive for a higher framerate)

    expect between 20 FPS for large saves and 45 FPS for smaller saves

    You CAN change the resilution of TPT for higher performance (45-60 FPS), but don't expect any saves to load.
