Nice. Chain-building for almost all structures is awesome. Unfortunally, it doesn't work for modules. I tried factory upgrades (starting at T4 for immediate test) and dericks at some hi-oil maps, with continuous, gapless rows of oil resources. When drafting, there are no errors (as when crossed defense row crossed unusable terrain) and building is queued. But as soon as time to build comes, they disappear so immediately, that builders don't even jitter in build site direction.

Could be due to different handling for single objects and dragged chains.

How do the different graphics backends compare? Specifically on Windows?

As far as I understood the OpenGL delivers the best performance. :)
