On my machine the log lives in C:\Program Files\Steam\steamapps\common\simcity 4 deluxe\apps. The setting isn't a miracle setting that makes SimCity perform perfectly, but it does significantly improve scrolling performance to where I can actually play the game. I still get slowdowns when zooming and scrolling, although I believe this is due to it having to reload resources at the new zoom levels.

Yes, it should go in the Standard Hardware section. I didn't notice anything about back buffers in that file. However, when you run SimCity it'll generate a log in the executable directory (at least with the Steam version), and in that log is a dump of all its options and properties. That's how I found usevertexbuffers, so you may give the log a try to see if there's anything else useful to you.

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).
