I get an Excecption from this action when I run my program:
rtGradient = new RenderTarget2D(graphics.GraphicsDevice, image.Width,
mage.Height, 1, SurfaceFormat.Rgba64);
But when I use:
rtGradient = new RenderTarget2D(graphics.GraphicsDevice, image.Width,
mage.Height, 1, SurfaceFormat.Color);
everything is allright. Is this because my graphic card is to old to support Rgba64 or can I fix it in some other way?
