    NullDC Framerate Issues

    When I boot the game I'm currently trying to play (Shenmue 1 PAL) everything runs smoothly at almost full speed.
    After a few minutes the framerate drops heavily indipendently from where I am in the game (obviously the more stuff there's on screen, the more it drops). The only solution I found to make it go back to full speed has been to change the resolution from the NullDC menu: changing to any resolution briefly solved the problem, then I had to do this again. Problem is that after doing it multiple times times the emulator crashes.

    Laptop specs
    Windows 7 64bit SP1
    Intel Core i7-2630QM CPU 2.00Ghz (up to 2,9), 4,0GB RAM
    NVIDIA GeForce GT 540 M, up to 1760 MB RAM

    NullDC 1.0.4 Settings (I left the default options where not specified)
    Graphics, nullDC PowerVR -- Direct3D HAL
    GDRom, Image Reader plugin by drk
    Sound, nullDC AICA
    Sound CPU, VBA ARM Sound Cpu Core
    Input, PuruPuru (I'm playing with a PS3 controller tricking the computer into thinking it's a Xbox360 controller)
    Saves, nullDC VMU
    Ext Device, nullExtDev
    Enable Dynarec
    Enable CP Pass
    Cable, VGA (1) (I'm playing PAL)
    System Region & Broadcast Format, default
    Native resolution
    Palette Textures, versioned
    Sort, triangle
    Modifier volume, off
    Sync Audio
    Mute CDAA

    Thank you in advance!

    Here are the settings I use and it is mostly 60 FPS. If it goes lower it normally goes to 50 FPS or so.

    I thought NullDC is already dead. Demul is the only one that is actively right now.
