How can it be hardware when it worked fine a few weeks ago?
My point exactly. Let's say there are 2 know possibilities for lag. Tourism and GPU performance. ( the OP has a good network connectiion)
Since the tourism and GPU info weren't provided by the OP, we have to take a logical approach. If you start a new city, you eliminate tourism as a factor. You have to take up Gambling or add a Tourism module to City Hall to trigger the issue. That takes a while. Days, weeks.. ??
If it runs fine without those, then there's a good chance that Tourism is the issue, otherwise it's the GPU.
Just saying. IF..THEN..ELSE.
