Yes. Several GB. I had to enable half resolution to play modded Space Age.

Hmmm... The Factorio team is famously performance oriented, and more scenes are often far less so. Are you sure the problem wasn't the mods? I have good memories of sending my Kerbal frame rates to hell with generous modding, both for graphics and the physics engine.

		I also struggled with performance in space age and mentioned it to a developer, but the solution was setting a setting which I had tested previously (no fog) and did nothing... on Nauvis. Turns out it's the difference between stuttering and smooth when in space platform view. They do still care but I guess there's only so much you can do if you also have other tasks to get to

		Reporting the issue with mods to the team will likely get them to fix something - they're that performance oriented.
