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

    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
