Once it starts it never seems to go away. Also, it's a newish PC (March) so I don't know whether the drivers are an issue. Haven't had any weirdness with any other games, and I've played a bunch that are newer and much more demanding on the hardware than SH4. But, thank you for taking the time to reply!

Thank you. I saw a write-up about Large Address Aware and I have done that to SH4.exe. I'm on Windows 10.
