This sounds really cool. Please bear with me - whether you believe it or not - 
I have little knowledge about OpenGL and rendering in general, let alone the 
theory behind ray-tracing. But from what I have gathered, resolution seems to 
be a heavy factor on framerate. What order of magnitude does the 
computational complexity rise with higher resolutions?

I have made a newer patch, that applies against the latest rev 1270.

It does not have any significant changes since ioEF 1.37, just fixed the

Thank you, I am really happy that you found and used my patch. That is what 
Open Source is all about.
My motivation behind the patch really was so I could play it natively without 
wine, and I still play it today from time to time even almost 8 years after 
the game was released.

By the way: as far as I gathered, most of the raytracing stuff is CPU based. 
Are there any plans to load tasks to the GPU?
