Thread: set maximum frame rate

  1. #1

    Default set maximum frame rate

    G'day All, is there a way to set a maximum frame rate (say 30fps) so as to take some of the load of my PC it can get quite good rates but when the rate fluctuates is when the PC gets the jitters.
    Regards

    The only option that does anything like that is vertical sync.
    Cheers

    G'day Derek, I have vertical sync checked but it does not seem to do much.

    That will hold it to 60fps.

    Have you turned off all shadows,
    turn off distant mountains,
    Cheers

    G'day Derek, here are my PC specs -
    Processor = Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz (2 threads, 2 cores, 2.4 GHz) (Internal Cache 64 KB) (External Cache 3072 KB)
    Memory = 4.0 GB
    Video = NVIDIA GeForce GT 430 (1.0 GB RAM) (nvlddmkm 10.18.13.6472)
    Display = \\.\DISPLAY1 (1280 x 1024, 32-bit, primary, 0 x 0)
    Sound = NVIDIA High Definition Audio
    Disk = C: (Local Fixed Disk, NTFS, 200.0 GB, 147.7 GB free)
    Disk = D: (Local Fixed Disk, NTFS, 1663.0 GB, 991.7 GB free)
    Disk = E: (CD-ROM Disc, CDFS, 0.0 GB, 0.0 GB free)
    Disk = F: (Local Fixed Disk, NTFS, 931.4 GB, 108.1 GB free)
    OS = Microsoft Windows 7 Home Premium 64-bit

    I have all shadows turned off but as for distant mountains, if I turned them off I may as well go back to MSTS but I did trim them.
    The problem is that in places on routes there are areas where the frame rates drop and these are where you seem to get the jitter problem, if the frame rate could be capped at say 40fps then I feel that most if not all of the issues would go and anything that remained would be minimal. I know people will say to get a better PC but living on the pension I just cannot afford it.
    Regards

    Hi Barrie,

    You can't cap the frame rate at 40hz.
    With your system,you are always going to have trouble.

    G'day All, well with all the doom and gloom I decided that there is more than one way to achieve what you desire, so I started playing around with settings and seeing what results I could achieve. I will not bore you with the details of my testing but I have finished up with a pretty good result. Most routes are running at a fairly steady 60fps and very little stutter which for the most part are barely discernible.
    I will get back in a day or so with what the settings are as it may interest some who have similar issues, by the way I am using distant mountains still.
    Regards

    I suggest you also to check "Load day/night textures only when needed". It may speed up loading new tiles (world sections) and it also reduces memory used.
