    I will look into it... I'm running it on a 600mhz computer right here with navigation and it runs fine...

    .NET uses the CPU and memory it has available, it will use less on your car-pc because there is less available...

    well, im happy as a clam just having it operational. any improvements you make to it are totally bonus.

    the scrolling text doesnt exactly go very fast... why does ti take so much power to operate it?

    I have made modifications that improve the CPU performance...

    I will either post it later or it will be in the next release...

    I updated centrafuse.exe again....

    http://www.fluxmedia.net/downloads/C...se_VFD_Fix.zip

    Replace the one file like before...

    This decreases CPU usage, it's still a little high, but only while it's scrolling...

    It also properly turns on/off from settings without restarting the application...

    Hopefully this pretty much does it for HD44780 support...

    Please make scrolling switchable. I'm now seeing a 41% jump between having the VFD off (3%) and on (44%).

    This is on my home machine, 2.8Ghz Hyperthreaded P4 with 2gb of RAM.

    It's bad enough that there's a 2 second pause between hitting any button in the UI and seeing it acted upon.

    The work machine (2.4Ghz P4, 1.5gig RAM) is now UNUSABLE with the VFD enabled.

    CF in playback without VFD: 2.3%, with VFD: 67%-79%. I have keypress delays of over 5 seconds.

    You must be spinning in a loop... This is not because of .NET.

    weird... Centrafuse runs great on with VFD enabled on my P3 600mhz with 256 megs of ram...

    That is the machine I do all my VFD testing on.... CPU around 12%-18% when title not scrolling, with scrolling around 33% or so... This is with music playing of course...

    not sure what issue you are having...

    Okay, but it's happening on two different machines. Completely different installs of XP, same version and configuration of CF.

    I'd invite everyone to look at their CPU usage when running CF and compare the numbers with/without VFD enabled.

    One clue may be that the CPU usage seems to skyrocket on titles that have 5 characters scrolling versus just one. There's still a lot of overhead on scrolling one character, but I'm seeing double that amount when it's working on scrolling 5.
    if you remove the title from your VFD output through settings, what performance do you see...

    is it what you would expect?

    What about when the title is not scrolling at all, is that normal?

    This is only scrolling titles you see this high CPU usage, and you claim one 2ghz machine becomes unusable, which is hard to believe because I just tested again on 1 M10000, 1M6000, and a 600mhz computer with 50 character titles and the application was completly usuable... the CPU was high, but no lag...

    I agree CPU is high when title is scrolling and I might make a little flag for in the vfd.xml to disable it if you want for your machines and others that for some reason have issues with making the main app not respond...
