Hey everyone, I think I've stumbled across a fix for the slowness with hardware rendering. Open "Graphics Rules.sgr" in your SimCity 4 directory and add the highlighted line, and remember to turn hardware rendering back on:      property useSecondStage       false  # Default, overridden below in most cases.    property texBindMaxFree       4   # To stop thrashing, plus a little pad.    property dirtyRectMergeFrames 6   # Default, for low-end card.    property TextureBits          32  # mostly just for preview -- everything else                                      # should be DXT    property usevertexbuffers false   My hardware specs: Intel Core 2 quad-core Q9300 @ 2.5 GHz 8 GB RAM NVidia GeForce 8800 GT with 512 MB RAM Running windowed at 1920x1080.   Before the fix, scrolling performance was about 1 FPS. After the fix it was significantly smoother, at least 20-30 FPS.   Can other people give this a try and see if it works? Hardware rendering looks slightly better since better texture filtering is used (whereas software rendering uses nearest filtering which gives noticeable aliasing artifacts).
