    Hi,

    I am stuck on a memory issue for my application, the log is telling me that there is a maximum of 465973852 Bytes (about 466 MB) of memory available (since it crashes after this amount and I had no other video-heavy applications running), although the application is running on a machine that has a 970 GTX which has at least 2GB of video-memory available.

    I tested it on another PC with a GfxDevice of 2GB and got like 800 MB.

    The PC version of the application works fine on both machines.

    Is there any reason why a windows 10 store application wouldn't have access to the entire available gfx memory?

    Thanks in advance!

    Hi,

    don't confuse ALLOC_GFX memory with GPU memory, in this context ALLOC_GFX memory uses memory from good old RAM, so it has nothing to do how much video memory you have. Nevertheless you're out of system memory. I am not aware of memory limits for Windows Store Apps on desktop, there are memory limits for Windows Store Apps running on Windows Phone though.

    Without a repro project it's hard to say... but try opening task manager and see how much memory your app uses.

    Right, that explains a lot, I am building the application as x86 so then the max is reached quite easily. I'll attempt a x64 build which will probably solve al my problems for now.

    Thanks!
