"optimisation is poor"
Good lord, which part of "early access" isn't clear?
I think you may have inferred something that doesn't exist - I wasn't complaining.
Its not helpful to assume that optimization is or isn't subpar on any given build, so it is worth stating in feedback reports. I provided my hardware configuration so that the devs were aware of the optimization issues with my specific setup, and I'll continue to do so with each major update, because, it's an important component of QC and play testing. It also gives them an opportunity to track configuration-specific issues as they polish and improve the game.
