That horse of yours sounds strong enough to pull against a semi-tractor... You shouldn't have issues except around harbors or lots of planes. What mods are you running? How much do you have running in the background of Win10? Look in the SysTray (lower-right, by the clock), and see what-all is going there. If you are using a "Cloud" service, that might do the trick. Also, some AV scanners "live time" scanning might be hitting every file as the game opens them. Main thing though, is to open LAA again and select the SH4.exe file. Make certain that the LAA is set to "True". If you're in the "Basic" mode, it will have a tick mark in the check box when you select it. If you're using "Intermediate" or "Advanced" mode, it should say "LAA True". If not, then check the file in Windows Explorer, and make sure the Read-only attribute isn't set on its Properties page. Then use LAA and enable SH4.exe. Even still, in "high-traffic" areas of the game, the game's engine can't handle things smoothly, especially if you're using time compression...
