Hi Guys,
As we run really big screens here we need to wring every last bit of speed out of TG3 to get it anywhere near acceptable speed.
To help to do this we have the DrawingQuality of the form control set to HighSpeed. One draw back with this is that labels look lousy. it would appear from the help that you can control the DrawingQuality of individual layers, help has the following:-

The DrawingQuality enumeration allows you to control, in a macro sense, the drawing quality that will be used in the GeoCanvas. Each GeoCanvas, which is responsible for drawing of the features, may have its own specialized drawing quality properties. What the DrawingQuality enumeration does is define some general guidelines for each GeoCanvas. For example, if you set the DrawingQuality to HighSpeed, then inside of the GdiPlusGeoCanvas there is a profile for HighSpeed. This profile sets specific properties, such as the smoothing mode and composing drawing mode of the GdiPlusGeoCanvas. As each GeoCanvas may have different drawing quality properties, this offers a general way to control drawing quality and speed.
If you need complete control over how a specific GeoCanvas will draw, then you can set the DrawingQuality to Custom. This will tell the specific GeoCanvas to use the properties on its own object instead of one of the pre-defined profiles. If one of the profiles -- such as HighSpeed or HighQuality -- is set, then the specific GeoCanvas ignores its own properties for drawing quality.

The last paragraph looks like the solution we are looking for but how do you set the DrawingQuality to Custom when the enumeration does not have Custom in it?
To put it another way, what we are trying to do is to have only certain overlays draw at HighQuality, the rest at HighSpeed.
Any help would be appreciated.
