I was just wondering how to calculate the VRAM bytes required when using multisampling (full screen anti-aliasing) and double buffers.
Anyone have the formula?
I’m mostly wanting to know what my VRAM requirements are given multiple sampling (4 samples), a resolution of 1920 x 1080, 32 bit colour (RGBA), 24 bit depth buffer and double buffering enabled.
Is it simply 4 * 1920 * 1080 * 4 * 3 * 2 / 1024 /1024 = ~190MB?
