    Hi,
    I am getting this apparently common error when loading up a game with a lot of AI, but none of the posts I found online offer a solution:
    "critical memory allocation error"
    Rfactor2 failed to allocate a section of memory

    I am running the 64bit binary and using DX11. My specs are:

    Intel i5 (haswell)
    8GB DDR3 RAM
    Radeon R270
    Windows 10

    I tried deleting the bin64 directory and having steam redownload the files, but it didn't help. It used to work flawlessly back on windows 8.1, but I believe I was using DX9 back then. Does DX11 have higher hardware requirements?

    Thanks in advance.

    What are your windows swapfile / virtual memory settings? If you've limited that it could cause issues with that many AI, because you are simply running out of available memory.

    I imagine recent builds do use more memory than the old dx9 ones, yes.

    8 GB Ram is not that much nowadays.
    Check how much gets used from all running programs, when you load the game with "a lot of AI".

    Try:
    - Lowering opponent detail in the graphics settings.
    - Lowering texture detail in the graphics setting.

    It also depends on what car/mod you're loading, more resource hungry mods mean more power is needed, which mod are you trying with and which track?

    I was trying to load Hockenheimring with a Tatuus open wheeler. But IIRC the same issue also appeared when I was trying to load a replay of an old race I did a year ago that worked perfectly back then, I just dismissed that as a random crash back then.

    I kept the task manager up while it loaded to see if it really ate up that much memory. The system didn't even pass the 70% of total memory used when rF2 crashed. I tried running it in admin mode as well, I thought maybe it didn't have some permission to allocate more memory or something, but no cigar.

    It's not a problem for me to buy more RAM, but I want to know if that is really the problem, so far it doesn't look like it. Are there any actual hw requirements specifically for DX11 rF2? Could it be my GPU?

    Radeon R270 only has 2gb of GDDR ram, either do as MarcG suggests, or get a modern graphics card with more GDDR ram.
