    It was changed recently:

    [87645] Changed: Default memory allocator is now tbb4malloc_bi instead of tbb3malloc_bi

    Tried to run the PvP MemAlloc Suite with 89025, but with the default settings of that test it seems that Vsync is on...I was getting capped at 60 FPS for most of the tests. Is there a command to disable that? Also, is it possible to get more than just the average FPS, because that alone is not always the best indicator of performance. Be nice to have min and max as well.

    So now that tbb4malloc_bi is the default allocator, there is no more need to specify it into the shortcut target right? The allocator command should only be used if I want to use a different allocator than tbb4malloc_bi?

  5. #155
    Yes,but only with a beta patch (use latest one to be sure)

    tbb4malloc_bi is not the default allocator in 1.60 vanilla

  6. #156
    I had a crash while playing a long game on Warfare BE the other night on the latest beta. The .rpt indicates its something to do with tbb4malloc_bi:
    https://docs.google.com/open?id=0B4X...MyMDhjNDJkNDU2

    I am also trying to diagnose a separate issue which may be linked but need to test further. I think the client may be degrading over time performance wise in the latest betas, as I don't seem to get it on official 1.60 patch. It is time consuming to reproduce consistently though. I have reverted the beta to use tbb3malloc_bi, so will see how that goes.

    Specs are:

    Basically no change as far as I can tell.
    The latest beta has some better FPS with tbb4 and tc.

    Help: Got a crash? Report it! What is the RPT log file?

  8. #158
    Which memory allocator does last official patch use?

    Should I install latest beta with the tbb4 mem alloc?

    I think I am going to start tightening my ram timings.

  9. #159
    It uses tbb4. It will AUTOMATICALLY use tbb4 ... so not needed in commandline.
