that indeed appears to have fixed the entire issue its about as smooth as SimCity 4 non deluxe now.. maybe it's handy to put this info somewhere incase anyone else wonders across this. quite a few retro discords have complained about the issue before without a fix

sorry for the delay once again. for some reason i cannot log into my discord account that i used to sign up here? anyways. i checked out your suggestions and applied the string of text in graphiles rules.sgr. but nothing changed, i checked the log and nothing changed aswel. i'll attach both the log and the graphics rules since i see some info talking about the mac port in graphics rules file. used notepad++ on windows to edit it and then put it back in the sim folder Documents.zip edit i tried to change everything in the file to use the sample value for example property dirtyRectMergeFrames 8 now the log shows that it is indeed at 8 instead of 4. but no difference in performance theres a note attached to property noPartialBackingStoreCopies true saying not to enable this on the mac port. so i tried to enable it anyway by removing the # but it didn't change in the log. i feel like that option is what should fix the issues? i have noticed the SimCity 4 audio skipping when scrolling so definitely something with scrolling. i think the rules are not applied to begin with hence me having to manually change the values.
