TSH v4 Functionality Improvements
Priority Control
Forcing F18.exe to run at Normal priority instead of the default of High can improve Jane’s F/A-18 compatibility with controllers (such as the Saitek X-45 HOTAS and the Logitech G15 Gaming Keyboard) and voice communication programs (such as Ventrilo). BelowNormal priority can be used in other situations. Select the desired executable priority in the drop down box.
If you run F18.exe in Win98 compatibility mode, it will run at Normal priority regardless of the TSH Manager setting.
