Hi,
I have a MFC application that runs the multithreads with DirectX. The
application need a lot of video memory to initialize/render image and
video
at the same time, which I found it needs at least 256MB of video memory to
work fine. When the application runs at 128MB video memory, the image
will
disappear due to Out Of Video Memory. Here is my question, the company
that
I am working have a lot of computers with 128MB video memory at customers
sites, and we can't just go out to each machine to change the video memory
at
the BIOS. I wonder if anyone know how to increase the video memory to its
MAX at the run time of an application? Or, is there any way that can
solve
this Out Of Video Memory problem?
Perhaps they can update the video drivers so that a portion of the system
RAM is used to supplement the video memory on the card. For example, the
stock Vista drivers for my nVIDIA 8400 did not use system RAM and thus I was
stuck with the 256 MB already on the video card and could not use the card
at my preferred resolution of 2560x1600x32-bit color. But when I updated
the nVidia drivers by going to the nVidia website, I was able to do so.
