Agera One :
I need to know in what ways (every single way) lesser VRAM will affect games in a 1080p single monitor? Should I reduce level of detail? reduce settings? lags? FPS drops?
Anti-Aliasing is one of the biggest hogs of video memory. Anisotropic filtering consumes a fair bit of memory as well,
but it has almost no performance impact while sufficient memory remains.
Draw distance and object density also consume memory, but the effects of these are more heavily felt on the shaders first, so memory may not be an issue.
