VICE performance with CRT emulation on



  • Trying to get a decent performance out of VICE (non lr version) on Pi3 Retropie 4.2. The emu runs 100% @50FPS in FullHD native resolution if no filter is enabled. As CRT emulation is turned on, the performance drops to about 35FPS.

    I have tried overclocking but nor GPU and CPU overclock seem to bring benefits

    Highest overclock config I've tested as follows
    arm_freq=1300
    gpu_freq=500
    core_freq=500
    sdram_freq=500
    sdram_schmoo=0x02000020
    over_voltage=2
    sdram_over_voltage=2

    Any idea why overclock doesn't seem to affect performance?
    Also, one more question: anyone tried VICE+CRT emulation on Pi3+ and can report the results?

    Thanks in advance for any tip
