1) First of all I use (managed) Microsoft.DirectX.Direct3D.Font.DrawText(....) for creating 2d text and change x-y parametrers for scrolling 2) I can calculate framerate as below : ++frames; int ticks = Environment.TickCount; int elapsed = ticks - lastTickCount; if (elapsed > 1000) { int framerate = frames; frames = 0; this.FPS = framerate ; lastTickCount = ticks; } But how can i use them together and get a SMOOTH scroll ? Or am i on the wrong way ???

Do not cross-post this again.
