Small report:
1) your FPS is limited by VSync, so on mine system it's equal 60fps.
2) disabling VSync raises FPS to 100 - seems it's limited by timer/phisics when - NOT by 3D card. YEP: "DXTimer.Interval = 10" !!!
3) Cirillic text is rendered OK in mine Russian locale system.
4) Now text/graphics flickering awfully in "mission debrief" (first to display) screen in default mode. But when I disable VSync it's rendered correctly.
5) "destructor Destroy ; reintroduce;" --> should be "destructor Destroy; override;"
