im making a game that is using directX 9 C# and the sampleFramework that ships with DirectX. my problem is im using the first person camera and having a few problems 1st problem im just using normal CustomVertexto create my verts this code is placed in my onframemove function, then my DrawPrimitives call is placed in my rendering loop. my fps are way to low around and I cant seem to get the math right to put the particles in front of the camera, here is the code
//this is to create the verts
CustomVertex.PositionColored[] verts = (CustomVertex.PositionColored[])vb.Lock(0,0);
			for(int i = 0; i<number;i++)
			{
				float x = (start.camera2.LookAtPoint.X - start.camera2.EyeLocation.X) +- (Convert.ToSingle(random.NextDouble()));
				float y = (start.camera2.LookAtPoint.Y - start.camera2.EyeLocation.Y) +- (Convert.ToSingle(random.NextDouble()));
				float z = (start.camera2.LookAtPoint.X - start.camera2.EyeLocation.Z) +- (Convert.ToSingle(random.NextDouble()));
				verts[i].X = x;
				verts[i].Y = y;
				verts[i].Z = z;
				verts[i].Color = System.Drawing.Color.Red.ToArgb();
				}
			vb.Unlock();

//this is to draw
                        device.RenderState.PointSize = size;
			device.RenderState.ZBufferEnable = true;
			device.SetStreamSource(0, vb, 0);
			device.VertexFormat = CustomVertex.PositionColored.Format;
			device.DrawPrimitives(PrimitiveType.PointList, 0, number);

problem 2 when the player shoots a object(a mesh) by pressing the mouse key the particles dissapear and then follow the object until the object is removed from the screen any help would be great EDIT: changed 'code' tags to 'source' so they dont break the forum layout, and corrected typo in subject line...
