I lost shadows with 2.7.4 and I don't see them again in 2.8. To be precise, I do see shadows, but they don't relate in any way I can see to the objects that might be shadowed. Not sure if this is my graphics card as they seem to work for others, details are:
Graphics Card Vendor: NVIDIA CorporationGraphics Card: GeForce GTS 250/PCI/SSE2
Windows Graphics Driver Version: 8.17.0011.9621OpenGL Version: 3.2.0
Otherwise 2.8 seems a considerable improvement over its immediate predecessors, though I find the user interface has become very sluggish, though rendering peformance is fine. I click on an inventory item and can count to 3 before it responds.
