I have managed to implement multisampling under windows in my project. It is pretty straightforward and the results are indeed spectacular.
But I would like to ask a question. I have some form of text rendered which I need to make as clear and sharp as possible. So the biggest the number of samples, the better it is. I tried with 4x and 16x and there is a big difference in sharpness. Of course 16 samples is quite heavy for everything else. But if it is only for text, no matter how much it is, even if there is whole pages of it, performance won't be hampered.
So the question is can I change the number of samples in real time somehow? Use 16x when rendering text and then use less samples for everything else? Or I would have to destroy the window and recreate it with a new pfd?
