Well I am glad I didn't buy the game just yet, I will give it a few more months and see how it goes. Every major game usually has bugs that need to be ironed out once it's launched, but this one seems to be exceptionally bad across the board. I'm just speculating here, but I think they did a disservice by announcing it well before it was truly ready. Only to constantly have delays and as a result, the mounting pressure to release something. I feel like their goals were too ambitious, or potentially lacked focus. This seems to fall into the "I am focusing on too much and not sticking with the current plan." type scenario.
I do not remember everything from way back, but was ray tracing and such, always the focus from day one, or did they just decide to add it as they went. If so, it's decisions like this that can make, or break you. Personally I would rather not have them focus on things like ray tracing and just worry about making the game look good in general and most importantly work without too many issues.
