Render region memory improvement

[noldo]

I often work with stereoscopic images and render at fairly high resolutions; with complex scenes, I frequently run out of memory.
I tried splitting the render into four parts by setting a render region, but memory usage remains the same as for the full frame.
Is this an expected limitation?

Hi,
Render region can have an impact on rendering speed, but not on memory used for the big frame buffer.
Please have a look at the following lua script instead, it is reducing the frame buffer in smaller tiles to have an impact also on memory usage:
