make sure you enable this too, saves more resources when rendering:

you could use the simplify options to limit textgure size to something small and then run a quick test render with f12, then turn up the settings and re-render until your just within your systems memory capacity. Probably easier to just get more ram though if you can.


You can also use the simplify option to turn on camera culling, that'll ensure you're only using textures that are actually applied to materials that are currently in the camera's field of view. You have to enable this in the simplify settings but also on a per object basis in the culling section of the object properties. Easier to select everything and then hold alt whilst enabling, this way it enables the settings for all objects at once.
Any devs reading this, it would be a good idea to be able to exclude textures from simplification, such as the hdri or textures that will be viewed close up to the camera etc. It's either all or nothing at the moment.

@Jason Battersby (jbattersby) It looks like you're using a large HDRI which is too large to fit into memory when uncompressed. You can also see that you're getting a lot of disk activity on drive D as it has to use the page file instead of ram. I'd suggest getting a min of 32 gb ram, but you could try changing surface sampling to manual in the world properties tab, and reducing the value to something like 4096 or lower. It would be nice if there were two options here, one for viewport rendering and one for final rendering, or perhaps better still if the lighting only had to update when necessary, it seems to update even when changing material parameters at the moment, which results in a sloooooow experience.

We require a .blend file and exact steps to reproduce the problem using that .blend file.
