Hi,

   I am a CAM developer working with C++ and C# for the past 5 years. I started working on DirectX from past 6 months. I developed a touch screen control viewer using Direct2D. I am working on 3D viewer currently. I am very slow with working on Direct3D. I want to be a gaming developer. As i am new to this i want to know what are the possibilities to explore in this area. How to start developing gaming engines? Is it through tutorials? I heard suggestions from my friends that going for an MS helps. I am not sure on which path to choose. Is it better to go for higher studies and start exploring? I am currently working in India. I want to go to Canada and settle there. Are there any good universities there to learn about graphics programming? Sorry if I am asking too many questions but i want to know the options to choose to get ahead.

Most game developers don't write game engines, it's a fairly specialised sub-domain. Are you interested specifically in writing game engines, or do you want to work on games themselves?

I want to work on games but my aim is to develop a gaming engine that can be outsourced.

Waterloo's computer graphics program was highly regarded when I was in university. There are a ton of great computer science programs in Canada.

Thanks for letting me know. I will research more on this. 

One more question, which is better to develop a 3D viewer , opengl or DirectX?

GL vs DX has no better nor worse choice, it is all about advantages/cons ( doc / tools / platform / knowledge / drivers / features ) of each to balance with your needs.

The only piece of advice, if you are not a triple A studio, do not use dx12, it is not for you, and use dx11. The later is not going to die, and the former is only when you need a breakthought in large application and you can pay the price of 10 times more complexity in development and pain to afford it for the gain it can theorically provide.
