Question Average size of video framebuffer on Windows?

for first question..it depends on how many textures/sprites and theirs size/compression used...so from almost zero to whatever u have available?

for second question.. up to 1.5GB vram for single 4k video, it doesnt have to be dedicated, for just video system ram is fast enough aswell (cpu ram will get used once your gpu ram runs low)

The amount of VRAM used by the buffer that goes to screen is simply resolution in pixels x bit depth. For 4k x 2k x 32bits, that would be 32MB.

The amount of additional memory beyond that for processing stuff varies with the type of content and how the application uses GPU acceleration.

What software do you guys use to determine how much VRAM the system is consuming?
Open Task Manager, go to the "Details" tab, right click on one of the headers for the columns and select "Select Columns", then check "Dedicated GPU memory" (should be towards the bottom).

Though considering I'm getting a reading that doesn't make sense compared to what the Performance tab -> GPU page reports, it's likely this is how much memory is reserved, not actually in use.
