Another thing I'm wondering, I've been thinking about experimenting with some rendering techniques like rasterization with gpgpu by using something like CUDA. However, I have no CUDA experience and wondering if it would be possible to do so? Could there be certain advantages over just using Dx / GL?

I've seen real-time raytracers done with GPGPU solutions, but no rasterizers as far as I can remember. There's a good reason for a lack of GPGPU rasterizers though, as DX and OGL would always outperform GPGPU solutions as they can use the actual rasterizer hardware, while a GPGPU solution would need to do rasterization completely in software.
Maybe there are some obscure use cases where a GPGPU rasterizer would be actually useful, but in general it'd be better to stick with libraries like DX and OGL.
Well, gonna have to try the gpgpu raytracing then
